What does the engine of 1600 VAZ 2114 look like. Which VAZ engine is better. Disassembly and repair: Basic facts

If during the operation of the car engine, there are interruptions regularly, and the sound outgoing from exhaust pipe, it looks more like a tractor growl, this suggests that your motor troit. This problem needs to be solved, and promptly.

The main causes of trimming

If you say that you have a troit engine, many will answer - the cylinder does not work. But such an argument is not quite correct, since the cylinder ceases to work properly. However, there may be several reasons for any:

• Compression in the cylinders is too low;
• Ignition Candle faulty or partially does not fulfill its functions;
• The valves are poorly adjacent due to a long lack of adjustment;
• Nozzles contaminated or transfused, therefore need to be replaced;
• The oxygen sensor stopped functioning;
• Candle high-voltage wire received damage;
• The ignition coil is faulty;
• DPKV does not work (position sensor crankshaft);
• I broke the computer (electronic control unit);
• The timing belt flew or just jumped into several links;
• The air filter failed or contaminated.

Some problems literally immediately manifest itself in the form of a pretext of the cylinder, but others can show themselves only after a while. And this is the most unwanted event development scenario.

Primary signs of problems that can inform about the cylinder breakage, such:

1. Vibration rises, since the rhythm of the valves and the other rotating gearbox parts and power aggregate broken.
2. Fuel consumption increases significantly, because the injection system stopped working properly.
3. An unpleasant odor is coming from the exhaust pipe, which is explained by a high level of concentration of harmful impurities and unburned fuel.
4. The power of the power unit decreases noticeably, which negatively affects the dynamics and maneuverability of the car.

If you have noticed that the engine troit, but did not take any measures, it threatens you soon a full way out of the engine, to repair which may be impossible. When the injection of the injection 8 valve engine on the VAZ 2114, in a non-working cylinder constantly comes fuel. It does not burn, but mixed with butter, then turns into the crankcase. If the process continues for a long time, the oil loses viscosity, ceases to perform the role of lubricant, the parts operate on the limit loads, the metal turns into a chips. There is nothing good in this, let's say frankly.

What to do?

There are a number of events that are recommended when detected that the engine is troit. All will allow you to answer certain questions. Therefore, prepare to highlight a lot of time to your car.

The first thing you want to do is to determine the pretext of the cylinder. He is not alone there. For this you need:

1. Open the hood by running the engine at the same time;
2. Listen and remember the sound that now emits your motor;
3. In turn, remove the wires with the candles. If you remove the high-voltage wire, the sound must change. If, when removing the next high-voltage, the sound did not change, congratulations, you found a defective cylinder.

Now dismantle the problem candle and check it for functionality. To do this, you need a special key intended for removing the spark plugs:

1. Pay attention to the electrode. If it is clean, the whole, but on the head a lot of gary is most likely in the combustion chamber there are a large amount of dust. This speaks about the fault of the air filter in the air supply system;
2. If the GAR is present on the head and the electrode, which is noticeably burned, the mixture comes up poor, the combustion occurs with premature ignition;
3. If the head is in Gary, but the electrode is intact, the mixture was rich, and the ignition was submitted late;
4. Check the presence of spark. If it is, then the problem needs to look next. When there is no spark, it is recommended to replace it with a new one and check the engine performance with a new candle.

If your car with a fairly impressive mileage, to identify the causes of "Troji", it is recommended to perform the following operations:

1. Replace the ignition candles;
2. Remove old high-voltages and change them to new, high-quality. Sometimes banal microcracks on them lead to breakdowns and failure of the entire power unit;
3. Measure compression in a cylinder that does not work. When identifying violations, you may define that the valve or problem in the rings are burned;
4. Perform valve adjustment. In general, this procedure is carried out with a periodicity of 15-20 thousand kilometers in order to prevent;
5. Check if the ignition coil works. A common problem for VAZ 2114. Trying to repair it is not worth it, it is better to immediately change to a new one. It will not be worth a lot of money;
6. Replace Old air filter to a new similar aggregate;
7. Check if the timing belt is installed and functions.

If even these events did not give any result, we advise you to try out a few more effective methods Engine Recovery Recovery:

1. Check out electronic block Control. When problems are detected, immediately change the old electronic control unit to the new one;
2. Check the functionality of the system responsible for fuel supply. In some cases, you have to get to the nozzles;
3. Analyze the operation of the oxygen sensor. It is subject to repair, but it will be better to immediately replace the device;
4. Make sure the crankshaft position sensor is working. This is determined using the electronic control unit. It will give an error that indicates the presence of a malfunction. When problems with the sensor, there is nothing else, except to change it to a new one.

What to do if troit at idle

There is also a fairly common situation, the causes of which there is a total of three.

1. There were problems with fuel supply. Need to rinse fuel system And clean the nozzles ultrasound.
2. There was a malfunction in the ignition system. In such a situation, it is recommended to change the spark plugs, check the performance of the ignition coil, as well as install a new set of high-voltage wires.
3. Valves are not adjusted properly. You will need to adjust the valves. If the situation requires more cardinal measures, then the valves will have to change.

Situations when the engine troit is found in a huge amount of cars. The model of the domestic manufacturer AvtoVAZ in the face of the VAZ 2114 is no exception. This is not a sentence to your engine. Just need to quickly take appropriate measures.

If you intervene in the work of the unit at the very first signs of "Trojas", you will be able to avoid complex and expensive repairs. But when the situation is started on Samotek and check the node is postponed from day to day for later, get ready to spend huge money soon or look at all new engine To replace the old.

Each car detail It has its own stroke. The VAZ-2114 engine, unlike the other elements of the car, is subject to recovery, if it has not received hydrate, or damage to the case: both external and internal.

This article discusses the resource of the motor, as well as on some nuances of operation and increasing this indicator.

RESOURCE AND OPERATION OF THE ENGINE

VAZ-2114 engine in a context with the description of the internal elements

So as not to go around, yes, right, we will immediately move on to the issue of the motor resource .

So, according to technical documentation, the engine installed on the VAZ-2114 has a potential of 150,000 km.

With normal operation and careful terms, the life of this node can be extended to 200,000 km.

When to wait for overhaul?

Before considering what will be included in repair and restoration work on the engine, consider the factors that affect the increased wear of the main power unit:

• Mane ride . This factor affects the very first of all, since frequent engine overwhelms will lead to increased wear of the internal parts of the power unit. So, the measured ride can significantly extend the life of this constructive element. As practice shows, drivers that drive carefully and carefully, the repair of the vehicle nodes is less likely. Especially concerned with the engine than those who like to drive.
• Timely repair operations . Power repair is enough important factor In the resource of the power unit. So, in time not adjusted valve, or late can significantly reduce the resource.
• Maintenance . Timely maintenance, namely. This is due to lubricant Takes all the physical and chemical processes in the motor. The development of one of the details, namely, in the metal chips, everything will go.
• Quality used spare parts . From what part you want, it depends not only, but also the resource of the main power unit. Thus, the high-quality part has not only greater potential, but also less production, which in the form of residues can get into the oil.

16-valve engine VAZ-2114

Now that the main reasons that affect the potential of the engine work can also be considered the main concepts that will be included in the overhaul of the power unit, after the use of the use resource:

• Grinding the crankshaft to repair sizes under indigenous and connecting rod liners.
• Cylinder boring and choning board.
• Installing a new piston according to the size of the block boring.
• Replacing a set of motor pads.
• Repair or replacement of the oil pump.
• Replacing valves and guide sleeves.
• Replacing the camshaft.
• Replacing the water pump and other elements of the cooling system.
• Grinding the surface of the block and head of the cylinder block.
• and engine oil.
• Restoration work. For example, argon welding of the head of the block in the field of crack formation.
• Other works aimed at restoring the motor resource.

As practice shows, after overhaul Motor, the service life of the power unit is reduced. Usually, this figure is 120-130 thousand km of mileage.

Increase resource

Increasing the resource of the main power unit - this is the question of which many are struggling experienced motorists. This is due to the fact that foreign analogues of VAZ-2114 the real potential of the engine is 250,000 km and above. Therefore, every owner this car Will asked how to increase the motor resource.

Physically, it is practically impossible to do this, except for the option of replacing most parts, on sports type, which in quality exceed regular spare parts.

But, this option may not be suitable for all, since the price of such modernization is too high.

There is a second option that does not require attachments, and will also extend the resource not only to the engine, but also the rest of the car details. So, consider the conditions under which the engine resource can be increased to 250,000 km:

• Careful operation.
• Timely low repair.
• Regulatory maintenance According to all rules.
• Do not overload the engine. Rods and other loads negatively affect internal details.
• Do not allow catastrophic fault consequences, for example,.
• Installation of only high-quality spare parts.

conclusions

As can be seen from the article, the resource of the VAZ-2114 engine largely depends on the owner of the car. The manufacturer installed the average motor potential, which is designed for 150 thousand miles of run. But, every motorist, compliance with the rules of operation and carefully belonging to its transport facility can extend the resource of the main power unit to 250,000 km.

For a long period of production on the fourteenth model of AvtoVAZ, four modifications of the engine, differing in power, volume and other characteristics. Different modifications There were no privilege of more expensive complete sets, but were a consequence of improving the outdated engine.

Motor modifications VAZ 2114

For ten years of mass production VAZ 2114 installed on it:

1. 1.5i. Engine VAZ 2114 1.5 liters volume, with 8 valves. The maximum power was 78 liters. S. at 5800 rev / minute. Torque at 3800 revolutions / minute reaches 116 N.M. Per 100 km in the mixed cycle consumption of gasoline 7.3 liters. In this modifications of DVS Apply an injection inlet with control over EB, instead of outdated carburetor, installed a new camshaft with corrected phases. Thanks to the introduction of the injector VAZ 2114 into the engine, the engineers managed to increase the efficiency of the engine, increasing its power, and at the same time reducing fuel consumption. It became a big started step in the development of everything model Row FROF Volga auto plant.
2. 1.6I. In 2004, released a modification of an engine with an increased volume of 1.6 liters. He developed a power of 81 liters. from. At 5,200 revolutions / minutes and 125 N.M. With 3000 revolutions / minutes. In the mixed cycle, the engine consumes 7.6 liters of gasoline per 100 km. The VAZ 2114 engine with an injector and 8-valves received an increased volume due to a 2.3 mm cylinder height, which made it possible to make a larger piston stroke. The ignition module was changed by the coil. DVS turned out to be more powerful and environmentally friendly, but the fuel consumption increased compared to the previous model.
3. 16V 1.6I (124). Also in 2004, an engine with a volume of 1.6 liters was released, but already with 16 valves, that is, 4 for each cylinder. This motor has already had 89 horsepower on the flywheel at 5000 revolutions / minutes and 131 nm of torque on the engine speed 3700 per minute. The plant claims consumption in a mixed cycle of 7.5 liters per 100 km of mileage. Motor VAZ 2114 8 Valve with an injector received a refinement in the form of an increase in the number of valves up to 16 pieces. The remaining characteristics remained the same. The car began to meet the requirements of Euro-3 ecology, acquired an additional 8 horsepower and became a bit more economical.
4. 16V 1.6I (126). In 2007, this engine was strongly finalized, the volume remained the same 1.6 liters, but the capacity has already reached 98 liters. from. With revolutions of 5600 per minute, and the torque develops 145 N.M. For 4000 revolutions / minutes. Fuel consumption decreased to 7.2 liters per 100 km.

Above the old motor VAZ 2114 for 3 years worked well and made several changes:

• the connecting rod-piston group is facilitated by 39%;
• the timing of the timing was changed, it became automatically tensioning;
• the wells for valves decreased in size;
• the quality of the honing of cylinders has risen significantly.

All these and some less significant improvements have increased engine spininess and now he developed 98 liters. from. and had a peak of the moment 145 N.M. With all this, fuel consumption has significantly decreased.
It was the most successful of all and became a great dignity of cars that are completed.

Despite the differences in all VAZ 2114 engines almost the same device, they:

1. Row. Cylinders are located in the same plane for each other. The standard location for such a number of pistons, it provides a good heat sink and balancing when working, which eliminates the ingress of large vibration when working on a car body.
2. Cast iron block. The cast iron block is driving the engine, but opens the capabilities of tuning, such as the installation of a turbine with a large inflammation.
3. Four-cylinder. Four cylinders are considered optimal for budgetary, economical engines. When working, the pistons work in the order of 1-3-4-2, the engine is operating smoothly. For example, an additional balancing shaft is used on the Oka with a motor with two pistons, for quenching vibrations.
4. Injector inlet. The injector has become the main advantage of VAZ 2114 engines, the engine is controlled by a plurality of sensors that communicate with the ECU that controls all engine systems. This allows you to increase the efficiency of work, which has a positive effect on the power and consumption.
5. Distributed injection under the control of the ECU. The compilation of the correct mixture during the operation of the motor is fundamental to achieve good dVS characteristics. The electronic control unit allows multiple times to improve the accuracy of the formation of the mixture.
6. Piston diameter 82 mm. All blocks of engines VAZ 2114 coincides with the diameter piston group, what gives excellent indicators maintainability and tuning capabilities.
7. Recommended gasoline AI-95. Fuel with large octane number It has greater efficiency and stability of work. Also on it less freight valve and gasket.
   These are quite simple engines, it is easy to work with them, you can easily hold dIY repair or tuning to enhance power.

AvtoVAZ declares the engine resource in 150 thousand km of mileage, after that it will require major repairs. But with proper maintenance and regular oil replacement, every 8-12 thousand km, Motor VAZ 2114 can drive up to 250 thousand km without larger problems.

Bulk DVS requires a careful inspection of all nodes and aggregates. Mechanical damage indicate the need to replace the part. In addition, all gaskets and washers are changed in obligatory.

Different models of VAZ 2114 engines have their own, constructive disadvantages.

1.5i VAZ engine 2114 Injector 8 valves:

• early fuel injection systems were unreliable;
• the nuts fastening the exhaust manifold is better to replace the brass, since the factory execution is unreliable;
• flowing oil from under the fuel pump, the ignition distributor sensor and the valve cover;
• valve clearances require frequent adjustment;
• some cooling system nodes are rapidly wear out.

1.6i VAZ engine 2114 8 Valve injector:

• less rare, but also requires adjustment of valve gaps;
• big vibration and noise when working.

16V 1.6I L (124) VAZ engine 2114 Injector 16 valves:

The timing belt must be tightened by manually every 15 thousand km of mileage.

16V 1.6I L (126) VAZ engine 2114 Injector 16 valves:

• the TRP break leads to expensive repairs, because the valve is deformed. The belt state should be controlled much careful. The problem can be solved by installing a "bullshit" piston group;
• the main requirement is reliable the work of the DVS There are high-quality components and spare parts, so do not save on them.

Improving dynamic characteristics

For the budget improvement of the dynamic characteristics of the VAZ 2114 engine, you can take:

• to refine the inlet and the release, namely, to set the throttle of the larger size, the intake receiver and the release without a catalyst 4-2-1, called the "Spider" people;
• split gear for phase adjustment;
• non-standard camshafts;
• if you have 8 valve engine, the best solution will replace the GBC on the 16-valve;
• the refinement of the GBC of different complexity can increase the maximum power up to 120 liters. from. without loss of resource.

Tuning can reach up to the installation of turbocadduv, nitrogen pump injection and other means of significantly improving power, but all of them are quite expensive and reduce the engine resource.

When finalizing it is not necessary to forget that all procedures are required to complement the corresponding software for the control unit, otherwise your tuning can adversely affect the operation of the motor.

Useful video

Additional interesting information About DVS VAZ 2114 You can get, looking at the video below:

To repair the injection car itself, you need to know the principle of operation and the device, the injector is a car with fuel injection system. Only knowing the principle of the injector operation can be understood the cause of the malfunction and eliminate its homework itself.

On vehicles VAZ-21083, VAZ-21093 and VAZ-21099, a system of distributed fuel injection on engines with a working volume of 1, 5l is used in the variant design. The distributed injection is called because for each cylinder the fuel is injected with a separate nozzle. The fuel injection system reduces the toxicity of the exhaust gases while improving the driving quality of the car.

There are distributed injection systems: with feedback and without it. Moreover, both systems can be imported components or domestic. All these systems have their own characteristics in the device, diagnostics and repair, which are described in detail in the relevant individual guidelines for the repair of specific fuel injection systems.

This chapter is given only short description General principles of the device, work and diagnostics of fuel injection systems, the procedure for removing the components of the nodes, and also provide the features of the engine repair itself.

The feedback system is used mainly on export vehicles. In her release system, a neutralizer and an oxygen sensor is installed, which provides feedback. The sensor monitors the oxygen concentration in the exhaust gases, and the electronic control unit according to its signals supports the air / fuel ratio, which ensures the most efficient operation of the neutralizer.

In the injection system without feedback The neutralizer and oxygen sensor are not installed, and the co-potentiometer is served to adjust the CO concentration in the exhaust gases. This system also does not apply a gasoline vapor capture system.

Warnings

1. Before removing any injection control nodes, disconnect the wire from the "-" battery terminal.

2. Do not let the engine if the wire tips on the battery are poorly tightened.

3. Never disconnect the battery from on-board network Car with engine running.

4. When charging the battery, disconnect it from the on-board network, car.

5. Do not expose the electronic control unit (ECU) temperatures above 65 ° C in working condition and above 80 ° C in non-working (for example, in the drying chamber). It is necessary to remove the ECU from the car if this temperature is exceeded.

6. Do not disconnect from the computer and do not attach the connectors of the wiring harness when the ignition is turned on.

7. Before performing electric arc welding by car, disconnect the wires from the battery and the wire connectors from the ECU.

8. All voltage measurements perform a digital voltmeter with an internal resistance of at least 10 mΩ.

9. Electronic components used in the injection system are designed for very small voltage and therefore can easily be damaged by electrostatic discharge. To prevent damage to the ECU electrostatic discharge:

Do not touch your hands to the ECU plugs or to electronic components at its boards;

When working with the PPZ of the control unit, do not touch the chip conclusions.

Neutralizer

The toxic components of the exhaust gases are hydrocarbons (unburned fuel), carbon monoxide and nitrogen oxide. To convert these compounds to non-toxic, a three-component catalytic converter is used, installed in the release system immediately behind the fuel receiving tube. The neutralizer applies only in the fuel injection system with feedback.

In the neutralizer (Fig. 9-33) there are ceramic elements with microchannels, on the surface of which catalysts are applied: two oxidative and one recovery. Oxidative catalysts (platinum and palladium) contribute to the transformation of hydrocarbons in water vapor, and carbon oxide into harmless carbon dioxide. Recovery catalyst (Rhodium) speeds up chemical reaction restoration of nitrogen oxides and turn them into harmless nitrogen.

To effectively neutralize the toxic components and the most complete combustion of the air-fuel mixture, it is necessary that 1 part of the fuel accounted for 14, 6-14, 7 parts of the air.

Such a dosing accuracy is provided by an electronic fuel injection system, which continuously adjusts the fuel supply, depending on the operating conditions of the engine and the signal from the oxygen concentration sensor in the exhaust gases.

A WARNING.

The engine is not allowed with the engine with a neutralized gasoline. This will lead to a rapid failure of the neutralizer and oxygen concentration sensor.

Electronic control unit

Electronic control unit (ECU) 11 (Fig. 9-34), located under the instrument panel on the right side, is the control center of the fuel injection system. This unit is called another controller. He continuously processes information from different sensors and manages systems affecting the toxicity of exhaust gases and on performance indicators car.

The following information enters the control unit:

On the position and frequency of rotation of the crankshaft;

On the mass air flow engine;

On the temperature of the coolant;

On the position of the throttle;

On the presence of detonation in the engine;

About voltage in the onboard network of the car;

About car speed;

About request for switching on the air conditioner (if installed on the car).

Based on the information received, the block controls the following systems and instruments:

Fuel supplies (nozzles and electric vehicles);

Ignition system;

Regulator idle move;

The adsorber of the gasoline vapor capture system (if - this system is on the car);

Fan engine cooling system;

Air conditioning compressor coupling (if it is on the car);

Diagnostic system.

The control unit includes the output chains (nozzles, various relays, etc.) by closing them to mass through the output transistors of the control unit. The only exception is the fuel pump relay circuit. Only on the winding of this relay, the computer gives voltage +12 V.

The control unit has a built-in diagnostic system. It can recognize the problems of the system, warning about the driver through the check engine control lamp. In addition, it stores diagnostic codes indicating the fault areas to help repair specialists.

Memory

In the electronic control unit, there are three types of memory: an operational storage device (RAM), once a programmable constant storage device (FPZU), and an electrically programmable storage device (EPZU).

Operational storage device is a "notebook" of the electronic control unit. The microprocessor of the ECU uses it for temporary storage of measured parameters for calculations and for intermediate information. The microprocessor can make data into it or read them to it.

The RAM microcircuit is mounted on the ECU printed circuit board. This memory is highly dependent and requires uninterrupted power to save. With the termination of the supply of food, diagnostic fault codes contained in RAM and the calculated data is erased.

Programmable constant storage device. In PPZa is located general programwhich contains a sequence of working commands (control algorithms) and various calibration information. This information is an injection, ignition control, idle, etc. which depend on the mass of the car, type and power of the engine, from transmission ratios and other factors. PPZA is called a storage device of calibrations.

Fig. 9-35. Electronic control unit:

1 - Programmable Permanent Storage Device (PPZ)

The contents of the PPZ cannot be changed after programming. This memory does not need food to save the information recorded in it, which is not erased when the power is turned off, i.e. this memory is non-volatile. The PPZA is installed in the panel on the board of the ECU (Fig. 9-35) and can be removed from the computer and replaced.

PPZ is individually for each car picking, although on different models Car can be applied by the same unified ECU. Therefore, when replacing the PPZ, it is important to install correct number Models and configuration of the car. And when replacing a defective computer, it is necessary to leave the former PPZ (if it is regular).

The electrically programmable storage device is used to temporarily storing the password codes of the anti-theft system of the car (immobilizer). Password codes taken by the ECU from the control unit Immobili (if it is available on the car) is compared with storage in EPZU and it is allowed or prohibited to start the engine. This memory is non-volatile and can be stored without supplying power to the ECU.

Injector sensors

The coolant temperature sensor is a thermistor, (resistor, the resistance of which is changing from temperature). The sensor is wrapped in the outlet of the coolant on the cylinder head. At low temperature, the sensor has a high resistance (100 com at -40 ° C), and at high temperature - low (177 ohms at 100 ° C).

The coolant temperature of the ECU calculates the voltage drop on the sensor. The voltage drop is high on a cold engine and low on a heated. The temperature of the coolant affects most of the characteristics that the ECU controls.

The detonation sensor worst into the upper part of the cylinder block (Fig. 9-36) and captures abnormal vibrations (detonation strikes) in the engine.

Sensitive sensor element is a piezocrystalline plate. During detonation at the output of the sensor, voltage pulses are generated, which increase

with an increase in the intensity of detonation strikes. The control unit for the sensor signal adjusts the ignition to eliminate the detonation flashes of fuel.

Fig. 9-36. Location of the detonation sensor on the engine:

1 - detonation sensor

The oxygen concentration sensor is used in the feedback injection system and is installed on the muffler's receiving pipe. Oxygen contained in the exhaust gases reacts with an oxygen sensor, creating a potential difference at the output of the sensor. It changes from about 0, 1 V (high oxygen content - a poor mixture) to 0, 9 V (little oxygen is a rich mixture).

For normal work The sensor must have a temperature not lower than 360 ° C. Therefore for quick warm warming After starting the engine, the heating element is built into the sensor. "

Tracking the output voltage of the oxygen concentration sensor, the control unit determines which command to adjust the composition of the working mixture to feed on the nozzles. If the mixture is poor (low potential difference at the output of the sensor), then a command is given to enrich the mixture. If a mixture is rich (high potential difference) - a team is given for a depletion of the mixture.

The air consumption sensor is located between the air filter and the hose of the inlet tube. It is thermoanemometric type. The sensor uses three sensitive elements. One of the elements determines the ambient temperature, and the other two are heated to a predetermined temperature exceeding the ambient temperature.

During the engine operation, the overgoing air cools the heated elements. Mass air flow is determined by measuring the electrical power necessary to maintain the desired excess temperature of the heated elements above the ambient temperature. Sensor signal - frequency. Big flow The air causes the high frequency signal, and the low flow rate is low frequency.

The ECU uses information from the air consumption sensor to determine the duration of the opening of the nozzles.

Co-potentiometer (Fig. 9-37) installed in motor compartment On the wall of the air flow box and is a variable resistor. It gives a signal to the EBU, which is used to adjust the composition of the fuel-air mixture in order to obtain a normalized level of carbon monoxide concentration (CO) in. Exhaust gases at idle. The co-potentiometer is similar to the wint of the mixture in the carburetors. Adjusting the content of C using the co-potentiometer is performed only at the maintenance station using a gas analyzer.

Fig. 9-37. Co-potentiometer

The velocity sensor is installed on the gearbox between the speedometer drive and the speedometer flexible tip. The principle of the sensor is based on the Hall effect. The sensor issues rectangular voltage pulses to the ECU with a frequency proportional to the speed of rotation of the drive wheels.

The throttle position sensor is mounted on the side of the throttle and connected to the throttle axis.

The sensor is a potentiometer, one end of which is supplied plus supply voltages (5 V), and the other end is connected to the mass. From the third output of the potentiometer (from the slider) there is an output signal with an electronic control unit.

When the throttle turns, (from the impact on the control pedal), the voltage at the output of the sensor changes. With a closed throttle, it is lower than 0, 7 V. When the flap opens, the voltage at the output of the sensor grows and more than 4 V. should be with a fully open valve.

Tracking the output voltage of the sensor The control unit adjusts the fuel supply, depending on the opening angle of the throttle valve (i.e., at the request of the driver).

The throttle position sensor does not require any adjustment, since the control unit perceives idle (i.e., full closing of the throttle) as a zero mark.

The crankshaft position sensor is inductive type, designed to synchronize the operation of the control unit with an upper dead point of the pistons of the 1st and 4th cylinders and the corner positions of the crankshaft.

The sensor is mounted on the lid of the oil pump in front of the specifying disk on the generator drive pulley. A reference disk is a gear wheel with 58 equidistant (6 °) depressions. With this step, 60 teeth are placed on the disk, but two teeth are cut to create a "B" pulse (Fig. 9-38) synchronization ("support" pulse), which is necessary to coordinate the operation of the control unit with the VMT pistons in the 1st and 4 cylinders. The ECU on the sensor signals determines the rotational speed of the crankshaft and gives the pulses to the nozzles.

a - angular impulses; b - reference impulse

When rotating the crankshaft of the teeth, the magnetic field of the sensor is changed, putting the voltage pulses of the AC voltage. The installation gap between the sensor core and the disk tooth must be within (1 + 0.2) mm.

Request signal signal on air conditioning. If the car is installed on the car, the signal comes from the air conditioner switch on the instrument panel. IN this case ECU receives information that the driver wants to turn on the air conditioner.

Having received such an ECU signal first adjusts the idling regulator to compensate for the additional load on the engine from the air conditioner compressor, and then turns the relay controlling the operation of the air conditioner compressor.

Supply system

The air filter is installed in front of the engine compartment on rubber clamps. The filter element is paper, with a large filter surface area. When replacing the filter element, it must be installed so that the corrugations are parallel to the axial line of the car.

The throttle nozzle (Fig. 9-39) is fixed on the receiver. It doses the amount of air entering the inlet tube. Air intake in the engine manages the throttle, connected to the drive of the accelerator pedal.

The throttle pipe includes a throttle position sensor 4 and no idle regulator. In the running part of the throttle (before throttle and behind it), there are holes for the sifting of the vacuum necessary for the operation of the crankcase ventilation system and the adsorber of the gasoline vapor collection system. If a last system It does not apply, then the fitting for blowing the adsorber is muffled with a rubber plug 7.

The idling regulator 5 regulates the rotational speed of the crankshaft on idle mode, controlling the amount of air supplied bypassing the closed throttle. It consists of a two-pole step electric motor and connected to it cone valve. The valve is shifted or removed, according to the signals of the ECU. When the needle of the regulator is fully pulled out (which corresponds to 0 steps), the valve completely overlaps the air passage. When the needle is moving, then the air flow rate is ensured, proportional to the number of needle waste steps from the saddle.

Fuel supply system

The fuel supply system includes electrical displacement 5 (Fig. 9-40), fuel filter 6, fuel lines and ramp 2 injectors assembled with nozzles 9 and fuel pressure regulator 4.

Electrical junction-dwinked, rotary type, unsolved installed in the fuel tank. It provides fuel under pressure more than 284 kPa.

The electrical displacement is located directly in the fuel tank, which reduces the possibility of the formation of steam plugs, since the fuel is fed under pressure, and not under the action of the vacuum.

The fuel filter is built into the feeding line between the electrical space and the fuel frame, and is installed under the floor of the body behind the fuel tank. The filter is intimidate, has a steel housing with a paper filtering element.

Rampa 2 nozzles is a hollow bar with nozzles installed on it and fuel pressure regulator. The ramp of nozzles is fixed with two bolts on the inlet tube. On the left side (in the figure) at the ramp of the nozzles there is a fitting for controlling the fuel pressure, closed with a threaded plug 1.

The nozzles 9 are attached to the fuel rail, from which fuel is supplied to them, and their sprayers are included in the opening of the ink tube. In the holes of the fuel ramp and the inlet tube, the nozzles are sealed with rubber sealing rings.

The nozzle is solenoid valve. When the voltage pulse arrives on it, the valve opens and fuel through the sprayer of a thinly sprayed jet under pressure is injected into the inlet tube on inlet valve. Here the fuel evaporates, in contact with the heated parts, and in a vapor state falls into the combustion chamber. After stopping the supply of electrical im-

pulse The spring-loaded nozzle valve overlaps the fuel supply.

1 - body; 2 - cover; 3 - nozzle for vacuum hose; 4 - diaphragm; 5 - valve; A - fuel cavity; B - Vacuum cavity

The fuel pressure regulator 4 is mounted on the fuel rail and is designed to maintain a constant pressure drop between the air pressure in the inlet tube and the fuel pressure in the ramp.

The regulator consists of a valve 5 (Fig. 9-41) with a diaphragm 4, supproved by the spring to the saddle in the chassis of the regulator. On the engine running engine, the regulator supports the pressure in the nozzles ramp within 284-325 kPa.

On the diaphragm of the regulator, on one side, the fuel pressure is applied, and on the other - the pressure (vacuum) in the inlet tube. When the pressure decreases in the inlet tube (the throttle is closed) the valve of the regulator opens with a lower fuel pressure, the reassembly excess fuel on the drain highway is back to the tank. Fuel pressure in the ramp decreases. With an increase in the pressure in the inlet tube (when opening the throttle), the valve of the regulator opens up already with greater fuel pressure and the fuel pressure in the ramp rises.

Ignition system

The ignition system does not use the traditional distributor and the ignition coil. It uses a module 5 (Fig. 9-42) of ignition, consisting of two ignition coils and high-energy control electronics. The ignition system does not have mobile parts and therefore does not require maintenance. It also does not have adjustments (including the angle of the ignition advance), since the ignition management is carried out by the ECU.

1 - accumulator battery; 2 - ignition switch; 3 - ignition relay; 4 - spark plugs; 5 - ignition module; 6 electronic control unit; 7 - crankshaft position sensor; 8 - asking disk; A - approval devices

In the ignition system, the distribution method is used, called the "idle spark" method. The engine cylinders are combined into a pair of 1-4 and 2-3 and sparking occurs simultaneously in two cylinders: in the cylinder in which the compression tact (working spark) ends and in the cylinder in which the release tact is occurring (ISRA). Due to the constant direction of the current in the windings of the ignition coils, the sparking current in one candle always flows from the central electrode on the side, and the second - from the side to the central one. Candles apply type A17DVRM or AC. P43xls with a gap between the electrodes 1, 0-1, 13mm.

Ignition control in the system is carried out using the ECU. The crankshaft position sensor feeds the support signal to the computer, on the basis of which the computer makes the calculation of the sequence of the coils in the ignition module. For accurate ignition control, the ECU uses the following information:

Crankshaft rotation frequency;

Engine load (mass air flow);

Coolant temperature;

Crankshaft position;

The presence of detonation.

Gasoline Casting Sailing System

This system is used in feedback injection system. The system uses a method for capturing vapors with coal adsorber. It is installed in the engine compartment and is connected by pipelines with fuel tank and throttle. On the adsorber cap is an electromagnetic valve, which is switched to the control unit, the system operation modes are switched.

When the engine does not work, the solenoid valve is closed and a pair of gasoline from fuel tank In the pipeline go to the adsorber, where they are absorbed by granulated activated carbon. With the engine running, the adsorber is blocked by air and the pair is sucked up to the throttle nozzle, and then into the inlet tube for burning during the workflow.

ECU controls the purge of the adsorber including the electromagnetic valve located on the adsorber lid. When feeding on the voltage valve, it opens, releasing pairs into the inlet tube. The valve control is carried out by the method of pulse modulation. The valve turns on and off with a frequency of 16 times per second (16 Hz). The higher the air flow, the greater the duration of the valve inclusion pulses.

The computer includes an adsorber purge valve when performing all the following conditions:

The temperature of the coolant is higher than 75 ° C;

The fuel management system runs in. closed cycle mode (with feedback);

Car speed exceeds 10 km / h. After switching on the valve, the speed criterion changes. The valve will turn off only when the speed is reduced to 7 km / h;

The opening of the throttle exceeds 4%. This factor in the future does not play if it does not exceed 99%. With the full opening of the throttle, the ECU disables the adsorber purge valve.

Operation of the injection system

The amount of fuel supplied by nozzles is regulated by an electrical pulse signal from the electronic control unit (ECU). The computer monitors the data on the state of the engine, calculates the need for fuel and determines the necessary duration of fuel supply by nozzles (pulse duration). To increase the amount of fuel supplied, the pulse duration increases, and to reduce the fuel supply - is reduced.

ECU has the ability to evaluate the results of its calculations and teams, as well as memorize the experience of recent work and act in accordance with it. The "self-study" of the ECU is a continuous process that continues throughout the life of the car.

Fuel is fed by one of two different methods: synchronous, i.e. with a certain position of the crankshaft, or asynchronous, i.e., independently or without synchronization with the rotation of the crankshaft. Synchronous fuel injection - predominantly used method. Asynchronous fuel injection is used mainly on engine start mode. Forships are turned on in pairs and alternately: first the nozzles 1 and 4 cylinders, and after 180 ° the rotation of the crankshaft - nozzles 2 and 3 cylinders, etc. Thus, each nozzle turns on Once for the turnover of the crankshaft, i.e. twice for the full engine cycle.

Regardless of the injection method, the fuel supply is determined by the state of the engine, i.e. the mode of its operation. These modes are provided by the ECU and are described below.

Initial fuel injection

When the engine crankshaft begins to scroll by the starter, the first pulse from the crankshaft position sensor causes a pulse from the ECU to turn on immediately all the nozzles. It serves to speed up the engine start.

The initial fuel injection occurs every time when started. The duration of the injection pulse depends on temperature. In the cold engine, the injection pulse increases, to increase the amount of fuel, and on a heated - the pulse duration decreases. After the initial injection, the ECU switches to the appropriate nozzle control mode.

Engine start mode

When the ignition is turned on, the ECU includes the power transmission relay, and it creates pressure in the fuel supply line to the fuel ramp. The computer checks the signal from the cooling fluid temperature sensor and determines the correct air / fuel ratio for starting.

After the start of rotation of the crankshaft, the ECU operates in start-up until the turnover does not exceed 400 rpm or the mode of purging the "filled" engine will not come.

Engine purge mode

If the engine is "filled with fuel" (i.e., the fuel wet the spark plug) ", it can be cleaned by the full opening of the throttle while turning the crankshaft. At the same time, the ECU does not supply injection pulses on the nozzles and the engine must" Clean ". ECU Supports this mode until the engine turns below 400 rpm, and the throttle position sensor shows that it is almost completely open (more than 75%).

If the throttle is held almost entirely open when the engine is started, it will not start, since, with a fully open throttle, the injection pulses are not served.

Operating Fuel Management Mode

After starting the engine (when the revolutions of more than 400 rpm), the ECU controls the fuel supply system in operating mode. On this mode, the ECU calculates the pulse duration on the nozzles by signals from the crankshaft position sensor (information about the rotational speed), the mass flow sensor, the coolant temperature sensor and the throttle position sensor.

The calculated duration of the injection pulse can give the air / fuel ratio, differing from 14, 7: 1. An example of an engine can serve as an example, since the enriched mixture is required to ensure good riding qualities.

Operating mode for feedback injection system

In this system, the ECU first calculates the pulse duration on the nozzles based on signals from the same sensors as in the injection system without feedback. The difference is that in the system with feedback, the ECU also uses the signal from the oxygen sensor to adjust and fine adjustment of the calculated pulse to accurately maintain the air / fuel ratio at 14, 6-14, 7: 1. This allows the catalytic neutralizer to work With maximum efficiency.

Acceleration mode

The computer monitors sharp changes in the position of the throttle valve (on the throttle position sensor) and the signal of the air flow sensor and provides the supply of an additional amount of fuel due to an increase in the duration of the injection pulse. The enrichment mode during acceleration is used only to control the fuel feeds in transition conditions (when the throttle is moved).

Power enrichment mode

The computer monitors the throttle position sensor signal and the crankshaft rotation frequency to determine the moments in which the driver needs the maximum engine power. To achieve maximum power required enriched fuel mixture, and the ECU changes the air / fuel ratio approximately 12: 1. In the feedback system with feedback on this mode, the signal of the oxygen concentration sensor is ignored, since he. will indicate the enrichment of the mixture.

Definition mode when braking

When braking a car with a closed throttle, emissions can increase emissions

toxic components. To prevent this, the electronic control unit monitors the reduction of the throttle opening angle and beyond the signal of the air flow sensor and in a timely manner reduces the amount of fuel supplied by reducing the injection pulse.

Turning off the fuel supply when engine braking

When braking the engine with the transmission enabled and adhesion, the ECU may completely turn off the fuel injection pulses for short periods. Turning off and turning on the fuel supply in this mode occurs when certain conditions are performed on the temperature of the coolant, the rotational speed of the crankshaft, the velocity of the car and the angle of opening the throttle.

Nutrition compensation

If the supply voltage falls, the ignition system can give a weak spark, and the mechanical movement of the "opening" of the nozzle can occupy longer. The ECU compensates for this by increasing the energy of energy accumulation in the ignition coils and the duration of the injection pulse.

Accordingly, with an increase in the battery voltage (or voltage in the on-board network of a car), the ECU reduces energy accumulation time in the ignition coils and the duration of the injection.

Fuel failure mode.

When the ignition is turned off, the fuel is not supplied than the self-ignition of the mixture is eliminated with an overheated engine. In addition, fuel injection pulses are not served if the ECU does not receive support pulses from the crankshaft position sensor, i.e. it means that the engine does not work.

Turning off the fuel supply also occurs when the maximum permissible speed of rotation of the engine crankshaft is 6510 rpm, for the engine sewn from the twist.

Controlling the cooling system electric fan.

The electric fan turns on and off the ECU depending on the temperature of the engine, the rotational speed of the crankshaft, the operation of the air conditioner (if it is on the car) and other factors. The electric fan is included with the K9 auxiliary relay located in the mounting unit.

When the engine is running, the electric fan turns on if the coolant temperature exceeds 104 ° C or a request to turn on the air conditioner. The electric fan turns off after the temperature drop in the coolant temperature below 101 ° C, after turning off the air conditioner or stop the engine.

Car VAZ 2114 The people are just four, is a popular front-wheel-water five-door hatchback, published to replace the VAZ 2109. The car saw the light in 2001. He is a representative of the Samara series 2, simultaneously with a three-door VAZ 2113 and a sedan VAZ 2115. In essence, VAZ 2114 is a restyling of the old nine. The appearance became more modern, also updated the salon. VAZ 2114 can be called a kind of "folk" car, as its popularity has a huge population. In the article, we will look at the engines that put on the VAZ 2114, we will touch their characteristics and disadvantages.

Engine 2114/2111

The VAZ 2111 engine which is popular with 2114, in general is eighty-third engine. However, in contrast to 21083, an injector is used to 2114, and not a carburetor. In addition, for 2114, the presence of a floating rod and another camshaft. Finally, 2114 has a greater power. VAZ engine 2114 1.5 liters. In line, injector, with four cylinders, has the upper arrangement of the camshaft, the timing belt is used in the TRG drive. At the same time, when the belt is cut, the valve engine does not oppress.

Disadvantages of the engine

In terms of flaws, the following are noted. It is necessary to adjust the valve, the parts of the cooling system quickly wear out, a frequent replacement is required. oil filter, problems with the valve cover seal, fuel pump and the distributor sensor. Can break the fastening of the exhaust pipe, as steel, not brass nuts are used.

In addition, often starting to float. The engine can told. Often the engine does not heat up to the desired operating temperature. The problem is most likely in the thermostat. In addition, the engine can knock and noise, usually due to non-regulated valves.

Engine VAZ 11183/21114.

Engine 21114, having a second index 11183, is the development of ideas laid down by a power unit 2111 1.5 l. And directly, 083 engine. The engine has a higher cylinder block, increased piston stroke, and 1.6 liters volume. The engine has elevated ecological indicators, and greater reliability.

Compared to VAZ 2111 engines of VAZ 11183, it is less capricient, more elastic and tracked. If you compare these two engines, it should be noted that they are going to although at one plant, but on different lines. This is an inline engine of injector type, with four cylinders having the top arrangement of the camshaft. The timing belt is used in the timing drive. With its cliff, the valve engine does not oppress, however, in the presence of a sports evil camshaft, the risk of problem outcome is possible.

Disadvantages of the engine

The engine has the following weak sides. The need to adjust valves in a timely manner. The engine can make noise and die, generally it should be noted that the engine is quite noisy, a variety of extraneous sounds and knocks for it, this is the norm. Finally, the engine is characterized by trimming, overheating or opposite the problem with warming up to the working condition.

Engine VAZ 21124.

AvtoVAZ within the framework of development 16 valve engines In 2004, he replaced the VAZ 2112 engine at 124 power units. It applied a higher block from viburnum on it, the piston stroke also increased by obtaining a working volume of 1.6 liters. Adapting 124 Engine to Norm Euro-3 increased its environmental performance. In addition, now there is a traction on the Nizakh, and there is a calmer operation of the engine.

Engine 21124 1.6 l., It is a row engine, an injector type with four cylinders and has the upper arrangement of the camshaft. The timing belt is used in the timing drive. With its cliff, the engine does not oppress the valve, thanks to the special wells. According to official data, the engine 21124 has a resource of 150 thousand km, whereas practically it reaches 200-250 thousand km.

Disadvantages of the engine

First of all, it is necessary to note the requirement to regularly tighten the belt of the gas distribution mechanism. In addition, the engine is characterized by trimming, knocks and noises during operation. Also, the engine is susceptible to overheating. Despite these shortcomings, according to the reviews of the owners, the VAZ 21124 engine can be called one of the best power units from the VAZ.

Engine VAZ21126.

The engine 21126 is a continuation of the VAZ 21124 power unit, which has a lightweight 39% SPG from Federal Mogul. This is an engine with reduced holes under the valve, and the timing belt, which has an automatic tensioner. Due to this, the problem of the timely belt tension disappeared.

In part of the block, we have better surface treatment, high requirements for honing cylinders under Federal Mogul. VAZ 21126 1.6 liters. It is an inline engine of injector type, it has four cylinders and the upper arrangement of the camshaft. In general, the engine is considered to be not bad, especially for the city.

Disadvantages of the engine

Owners note uneven operation, the loss of engine power. In addition, the timing belt is not particularly reliable. Overlooking the engine can be due to problems with fuel pressure, violation of the operation of the timing, a malfunction of the sensors, air seats through the hoses, throttle fault. In the case of power loss, the reason should be sought in low compression of cylinders, wear of cylinders, piston rings, triurand the pistons. When the timing belt is closed, the valves can bend valves. The problem is solved by the replacement of regular pistons with darkness.
