If you compare the ignition systems of all vaza models from rear wheel drive And priors, then immediately becomes noticeable by their great differences. On the "Classic" installed one, and the high-voltage voltage on the candle gives the ignition distributor. The coil is available on each cylinder, the electronic control unit is engaged in the distribution of voltage according to candles.
Device and principle of operation
Probably, all drivers are clear that the main purpose of the high-voltage coil was and remains one, it is a pathery of the fuel-air mixture. For this, it produces high voltage, the magnitude of which is about 40 thousand volts.
It is a transformer that increases low voltage rechargeable battery in high. The transformer consists of two windings, one of them is primary, and the other will be secondary, wounded with copper wire on the iron core.
The primary winding is wound on the core, and the "secondary" is wound on top of it. The whole design is closed by a casing. If the low-voltage winding has only about 150 turns, the "secondary" already has several thousand.
High-voltage wires are absent, as it dresses directly on the candle. When a pulse on the "primary" of the coil is received at the right moment from the engine control unit, the magnetic field is excited around the core, which contributes to the emergence of high voltage in the "secondary". In this case, the candle performs the role of the arrester, which sets places the working mixture in the engine cylinders. The coil has a protective shell, and the spring and diode is additionally installed inside it, which is designed for rapidly cutting high voltage pulses.
About signs of fault coils
The ignition coil on the prior, upon failure, immediately gives to know the driver about his "illness". This will be evidenced by such manifestations:
- Broken, it has vibration, the thrust is reduced, the drivers say that the motor "Troit";
- Machine jamming during acceleration or when moving on low gears;
- There are cracks or gaps in isolation.
The first item may also testify about non-working ignition candles.
How can you check the coils
In any case, checking the ignition coil on the prior always begins with its external inspection. Even very small cracks or ruptures on its rubber bands are not allowed. Their presence indicates the replacement of the device. Cracks, chips and other damage to plastic parts, suggest that the coil was overheating, and she could simply "overdo it." The following is an inspection of internal parts, especially the helix, its location. If the inspection did not find visible defects, proceed to further verification.
Check the ignition coil can be in several ways that will be discussed below. In the process of operation, the car is infrequent, but there is a need to check it. Do it when there are no obvious signs of failure, not so simple without special equipment, such as a spark discharge or oscilloscope. Let's look at the ignition coil without instruments. For a start, you can place and see how the motor will behave after that. If the interruptions moved to the coil, it means that there is a malfunction, it needs to be replaced.
Check the high-voltage ignition coil can be directly by car. To do this, it should be removed from the motor, in the high-voltage output to insert a good candle, with the ignition on ,. A good coil will be sparking on the candle . It is necessary to beware of high voltage and use protective agents.
In cars, which are installed, the system will report problems in the cylinder signals in the form of numbers from 0301 to 0304, where the last digit indicates the number of "problem" cylinder. It remains only to figure out who is to blame, a coil or a candle.
Tool check coil
After visual inspection and control, you can proceed to check with measuring instruments. It is best to use digital multimeters for these purposes, or instruments such as MD-1 or AZ-1. They can be free to buy, they are low. Now let's talk about how to check the ignition coil on the prior using instruments.
Before checking the device needs to be removed from the engine. This can be done in this way:
- Turn off the battery terminals;
- Remove the protective plastic casing with the engine;
- Press the retainer with your fingers and disconnect the connector with the wires;
- The key to "10" swell the fastener bolt and take out the coil from the installation socket.
We unscrew the coil with the key - everything is simple! (Naturally ICT 16 valves, coil with candles in the well) Now you can proceed to check appliances. First you need to check and calibrate the measuring instrument. To do this, the measurement switch is set to a position for measuring the resistance to the "200 Ohm", and the probes are closed with each other. Indications must be close to "0". These readings need to be remembered or recorded. They can later come in handy. The device is calibrated, you can start checking. Checking the multimeter is carried out in this order:
- Both appliances probe are connected to the coil connector (polarity not necessarily) and measured the resistance of the primary (low-voltage) winding. Pinout contacts for measurement 1 and 3, measurement limit of the device "200 ohms". It should show approximately 0.8 ohms. From this value, the indicator obtained during calibration is taken and obtain the true value of the winding resistance. If there is no reading, you need to check the reliability of the contact of the probe and the conclusions of the coil. If, after several attempts, the testimony will not appear, it means, in the primary winding, the opening, and it is subject to replacement;
- The next action will be directed to check the high voltage winding. Install the measurement limit in 2 MΩ. In this case, the polarity must be observed, since the high-voltage winding. Therefore, the red probe is inserted into the output of the coil, and the black is connected to the output of the connector at number 2, it is medium in the block. The device must show approximately 342 com. It should be considered the fact that the testing of the device is highly dependent on the heating of the coil. It is best to check on a cold coil. In this case, it is also necessary to achieve a good contact of the probe to the device with high-voltage conclusion. If the readings are close to infinity, it is necessary to replace the part.
A little about whether the repair of the ignition coil is possible. It is not possible to restore the primary or secondary winding, but to replace the tip on it completely under the power even novice drivers. To do this, stock:
- New tip:
- New sealing ring;
- Means for degreasing;
- High-temperature silicone sealant.
The place of installation of the tip is cleaned and carefully degreased. A new tip skirt should be turned inside out and put a small layer of sealant on it. While he dries a little, make the installation of a new sealing ring. Next you need to install a rubber tip on your place. This will repair will be completed.
A few words about choosing coils
According to experts and owners, the ignition coil on the prior is best suited by Bosch. Its cost is about 1,500 rubles, but it is worth it. Such products are sold necessarily in the individual packaging of yellow color. Original coils of this company are able to serve more than 100 thousand km of run.
74 75 76 77 78 79 ..Check the ignition coil and its Lada Priora chains (VAZ-2170)
To check the performance of the ignition coil, we reset the pressure in the engine power system and do not install the fuse fuel pump (cm. "Replacing the fuel filter"). Remove the ignition coil (see "Checking the state and replacement of spark plugs"). We insert into the rubber tip of the coil is a deliberately good ignition candle and connect to the coil a block of wiring engine control systems.
We have a candle on the cover of the cylinder head ...
... so that there is a contact between the side electrode of the candle and the "mass" of the engine.
To avoid damage to the current when turning the crankshaft, the starter does not touch the spark plug and the coil tip, and hold the coil for its plastic case. ... There should be a spark regularly between the candle electrodes.
Assistant, translating the key in the ignition lock to the "Starter" position, turns the crankshaft.
With good ignition coil and its chains ... 
If this is not the case - it is necessary to check the power chains and the coil control. To check the power supply chain, the coil disconnect from it a shoe of the engine of the engine control system ...
In the ignition system, the traditional distributor is not used ...
In the Ignition system of the car VAZ 2170 2171 2172 Lada Priora (Lada Priora), the distribution and moment of the appearance of the spark in the cylinders is monitored by the ECU. Sparking occurs consistently in those cylinders in which compression tact and, accordingly, the order of 1-3-4-2 is observed. The position sensors of the crankshaft and distribution shafts are fed to the ECU pulse "reference" signals, on the basis of which the ECU calculates the sequence of activation of the ignition coils. For accurate ignition control, the ECU uses the following information:
- rotation frequency crankshaft;
- engine load ( mass flow air);
- temperature of the coolant;
- the position of the crankshaft;
- position of the camshaft;
- The presence of detonation.
2. Removing and installing ignition coils on VAZ 2170 2171 2172 Lada Priora.
You will need an end head "on 10".
1. Disconnect the wire from the minus terminal of the battery.
2. Remove the decorative casing from the engine (see "Removing and installing decorative engine casing").
3. Squeeze the plastic lock of the electrical wiring pad
4. ... and disconnect from the output of the coil the block of wiring harness.
5. Remove the fastening bolt the ignition coil to the block head cover ...
6. ... and remove the coil from the candlestone.
P rimezhany looks like a sparkling coil of Lada Priora (Lada Priora).
Pay attention to its marking to replace a similar coil to replace.
Ignition coils are interchangeable and can be installed in any sequence.
7. Install the ignition coil in the reverse order.
The ignition system is a vulnerable place of priors, and not only it. The ignition coils in the car prior is individual, one on the cylinder, that is, only 4. It happens that one of them ceases to work, and together with it, one of the cylinders fall out of the working rhythm.
This is accompanied by vibration and incomprehensible sounds under the hood. Experienced motorists in such situations understand that the car Troit.
What is the coil for? To set fire to the fuel-air mixture in the cylinder, you need a high voltage current, and in car battery It is low-voltage. Thus, the ignition coil is something like a transformer, generating a current with a large voltage. Its primary winding consists of only 150 turns, and in the secondary their number is much more, which allows you to generate pulses using a spark plug as a discharger.
In order for the magnetic field to be as strong as possible, an iron core is located inside the coil. The main characteristic of the coil is the value of the resistance of its windings, which is accounted for in the diagnosis of ignition. The case of such an important node faces the full stop of the motor, not to mention the interruptions in the work.
Checking the health of the coil
The multitetester is a device that combines a voltmeter, an ammeter and an ohmmeter. Before connecting the device to the coil, it is necessary to check its internal resistance to take into account the possible error. After connecting the tester to the primary winding. If the device shows no more than 0.5 ohms, taking into account the measurement error, it means that everything is fine with this coil. In a sense, with its primary winding. But there is still secondary. How to check it?
It is necessary to remove the coil from its place by turning off the terminal minus the prior battery. Decorative plastic with motor is removed. Then it is necessary to squeeze the plastic lock and disconnect the coil from the wiring, after which the mounting bolt and the device is removed from the candle well to the key to 10.
Problems with coils threaten with sharp jerks in the operation of the motor, jumps of revolutions, cylinder failures. Therefore, in the presence of similar symptoms, it is better to take advantage of the above information and replace the suspicious item before it leaves finally. It happens that so that the coil has not yet broken, but already gives failures. It does not necessarily mean that it is necessary to replace, and some repairs will be used, more precisely cleaning from water condensate and dirt.
Sometimes coils fail with an improper gap in the ignition candlelight. Checking the performance of the coil on the vehicle car can be easily carried out by turning the crankshaft. To do this, you need to lose pressure in fuel system, Remove the fuse fuel pump. Then remove the coil, insert the spark plug into its rubber tip, connect the wires to the coil itself.
You can check the power supply chain. It is necessary to take the multi-seater mentioned above and connect it to the probes to its conclusions. If Ignition is at this moment, the tester should show the voltage equal to that on the outputs of the battery. Otherwise, it is necessary to check the chains on the break and closure. If the power chains and control are working, but when checking on a working candle inserted into the tip, there is no spark, then the coil is faulty, and it will have to be changed.
Repair tip
A cracked ignition coil tip is a common nuisance. However, it is possible to return the coil to the working condition by making the repair on its own, provided that the coil itself is not burned. This requires a degreasing napkin, silicone ignition coal ring (new), a new tip and silicone sealant. The whole procedure takes a couple of minutes.
We will wait for a while that the sealant fixed the item. The degreasing napkin wipe the whole coil, which is now returned to life. Pay attention to the contact spring, it should freely walk in the tip cavity. Required parts for work can be purchased on car markets and online stores. Good luck!
With numerous, and sometimes even in the case of minor ignition passes, the engine can work unstable, floating turnover will appear, the machine can twitch on the go, etc. To determine which one of the cylinders is faulty, it is necessary to remove the coil power plug alternately from each of them, more precisely - to disconnect it for a while.
If, in the case of disconnection of one of the cylinders, interruptions in the work are still present, it means that it lies the reason. Often, it is the ignition coil of one of the cylinders leads to the consequences described above. And to replace it, you will need the following tool:
- Head for 10 mm
- Extension
- Rattle or small knob
The order of removal and installation of the ignition coil by car Lada Priora with a 16-valve engine
Since the overwhelming majority of cars are equipped with 16-valve motors, then the whole process will be shown precisely on this force unit.
So, the first thing we open the hood of the car and disconnect the terminal "-" from the battery. Then we unscrew the plug of the fuel throat.
Also, disconnect the valve of the addition of the adsorber, moving a little to the side of the retainer lock. This valve is located with the right back of the lid (along the movement of the car).
Now you can remove the decorative engine cover, as it does not hold anything else.
With the help of the head with a rattle, we turn over the coil of the fastening bolt, as shown in the photo below.
And take it out after that this detail from the candlestone.
Since the coil sits quite tightly, you will have to attach at least a middle force to remove it from there. And in order to end it, it is enough to disconnect the plug with the wires, after pressing the latch retainer.
And disconnect it to the end, as clearly seen below in the photo.
Now you can take a new obviously good ignition coil and install in the reverse order. The price of the coil for priors is from 900 to 2000 rubles, depending on the manufacturer.
The Lada Priora has everything you need for the convenience of using the car:
The ignition coil is the most important node of the machine, and his breakdown will cause a huge number of trouble. Basically they will be associated with stopping and violations in the operation of the motor. The ignition coil is directly related to the node called "Draver". This is a distributor receiving on-board network Transport low-voltage food. The process of converting low-voltage in high-voltage power occurs. From the contacts of the distributor voltage using the "Runner" goes to the high-voltage wire for the candle. The split candle of each cylinder supplies a spark into the combustion chamber of the fuel mixture, there is ignition. For ignition, it is necessary to supply current to all candles, only then the motor will start and the machine will start moving. If not, vehicle It does not move from place.
Sometimes the car Lada Priora starts the engine, in other words, the motor performs its functions not full power. The reason for this behavior lies in the coil of electrode. The ignition system for this machine is unusual. Each candle has its coil, therefore, they are 4. So, the ignition can slow down four times more often than on other cars. As soon as one coil failed, the cylinder associated with it stops working. In individual ignition coils of any cylinder, adjustment is not required, since they do not have mobile parts. In the auto prior, the ECU reports the driver of a malfunction, monitors the distribution and moment of the formation of sparks. In the cylinders in which compression tacts end, sparking occurs. Exact pulses in the ECU are served from the position sensors of the crankshaft and distributional shaftsAfter that, the control unit reveals the sequential response of the ignition coils. Information transmitted to the system allows you to manage the entire process:
When problems with coils, you need to seek help from a specialist. To check the ignition coil, a special tool is needed - a multimeter.
Checking the ignition coil
Next, the secondary wiring is checked. The coil is located inside the coil, it is necessary to attach a red probe to it, and black to the second contact. You can measure resistance and on other coils, their prior machine has more 3. The device must show 340 ohms.
If there is no spark on the prior, the check is carried out using special devices that are installed at the location of the battery and show where the repair is needed. These devices are called MD-1, AZ-1. In this case, you should not seek help to mechanics, the device is quite inexpensive. You can do everything with him.
Removing and installing coil on the prior
All actions are carried out using the end head to "10". The "minus" of the battery is disconnected, squeeze the lock from the plastic, the wiring harness block disconnect from the output of the coil, turn the fastening bolt to the block cover, remove the coil from the candle block. When conducting repair work It should be remembered that a microprocessor high energy ignition coil is installed on the prior (MPSZ). High-voltage ignition wires produce a voltage of 40 thousand volts. Each who checks the coil must be extremely careful: there is a probability of lesion to the current. When performing an inspection, risky gloves will be saved from possible negative consequences. You can use PASSATISIA with pricked handles.
Types of coils
What spark plugs are suitable for a prior machine? It is worth remembering the quality of details and their condition. Sometimes candles have the wrong gap, it should not be less than 1 mm. To be confident in the performance of your car, it is better to change the candles and the ignition coil at the same time. This is important because the mechanism of contacts gradually wear out, it becomes unreasonable, resulting in sparking, fuel consumption increases.
Replacing the candles occurs as follows:
Spark plugs are screwed using a special key so that the sealing ring is in its place. After that, you need to pull the key with a key of 90 degrees. In the case of the installation of old candles, they are tightened only by 15 degrees.
An elegant "prior" is a car with a gasoline engine. And this means that the mixture in the cylinders is spawned. Well, this, in turn, requires the presence of a ignition coil (bobbins). Or sparking. How does this system work on the "Prior"? How it works, in general, the ignition system "Priors"? That's about it and it will be speech.
General principle of operation of the ignition coil, history
Like most active electrical devices, bobbin works on the induction effect. The essence is. A 12 volt voltage is constantly resolved onto the coil. There are two windings inside the device. High I. low voltage. The trick is that at the time of the circuit in the low voltage winding - 12 volts. In the second, internal, the short high voltage pulse is induced. Up to 24 chat. That is, 24 thousand. This pulse is supplied to the ignition candle, and high-temperature spark flames between its electrodes, ignites fuel mixture. There are three types of ignition system:
- Contact - 14-18 chat.
- Electronic - 19-22 chat.
- Electronic system Engine control (ECD) - 22-26 chat.
On the "Prior" it costs the ECM system. What is the difference from the rest, the usual installations.
Attention! The tension on the coils is really very high. Therefore, when working with them on the "Prior", it is necessary to comply with the safety technique.
Features Esud.
Cars equipped with these systems, in everyday life of drivers, are simply "Injectors". Here manages everything or correct the electronic unit Control. His drivers and locksmith is called even easier - brains. All the work of this enclave is a chain:
- "Brain".
- Sensors.
- Again the ECU.
- Executive mechanisms.
That is, there is a request for sensors, which, figuratively speaking, report on the "brains" on the state of the motor. In what position the pistons of the crank-connecting mechanism (CSM), in which position of the valve and so on. Checking, with the laid tables, the ECU gives the signals to the executing devices - nozzles, ignition coils and the idle system.
The main difference between Esud "Priors"
The fact is that For the "Priors" motor implemented the idea of \u200b\u200ban individual ignition coil for each candle. Since the engine has a 16-valve gas distribution mechanism, with deep wells to install candles, it allows you to perfectly implement this idea. So, on the "Priors" motor installed 4 sparking. On earlier models of cars with Esud, a module was installed from two paired coils. The inconvenience is that when you fail one of the windings, two cylinder is stopped at once. Either 1 and 4, or 2 and 3.
On the "Priory" with separate sparkors, on each candle its coil. That is, when breakdown, only one cylinder ceases to work. This allows you to get, with sin in half to the place of repair.
Caution! Some drivers may not even notice, or not to pay attention to the failure of one coil, and continue to exploit the "prior" in the usual mode. Do not do this. Such carelessness threatens the complete outlet of the motor, from the redistribution of the load in CSM.
The main signs of malfunction
Careful driver, professional, immediately pay attention to the atypical behavior of "priors". That's what will be noticeable:
- Increased vibration idling.
- Difficult running motor.
- Rod and "twist" when setting speed.
- Total power loss.
- The signal "Check Andger" is lit on the instrument combination.
With any of these signs, and also if they are present, it is necessary to find out the reason for the motor disorders.
Determination of faulty ignition coil
The indisputable advantage of cars with Esud is the ability computer diagnostics. But here there are some tricks. The ignition coil of the "Priors" can be three types of malfunction.
- Open chain winding.
- Short winding closure.
- Mechanical damage to the tip.
And diagnostics, clearly positions only the first fault. In other cases, the computer indifferently reports that skipping in the cylinder number is found. And here it is necessary to know the knowledge of the characteristics of the ignition system "Priors" to determine the malfunction. The fact is that other breakdowns can also give skipping. Such:
- Fuel nozzle failure.
- Non-working spark plug.
- Loss of compression in the cylinder.
How to determine that the ignition coil does not work
The method is not new, but very effective, and very simple. So, an alarming light of "Check" caught fire. And at hand there is no diagnosis. What to do? The procedure for such:
- Open the hood "Priors".
- Remove the decorative, plastic motor lid.
- Start the engine at idle.
- Remove the connector from the coil of the first cylinder. If this "boiler" is working, then his forced shutdown Let the motor work quite inadequately. Vibration will increase at times, tangible interruptions will appear.
- If everything is in order in this cylinder, then the chip dresses in place, and you need to move to the next one. So, in turn, all "boilers".
- But if the cylinder does not work, then when removing the connector, nothing will change. The level of work will remain the same, it means that the whole thing is here. But now clarify the degree of guilt of the ignition coil "Priors".
This is done as follows. Motor must be drowning. The head is taken at 10 and the knob. The bolt of fastening the sparking with a suspicious cylinder is removed. Just with the neighboring. Then they just change places. Fixed, and the motor will start again.
Attention! If signs of malfunction, that is, the lack of changing the cleanliness of the motor operation when disabled, moved along with the ignition coil to another cylinder, then everything is exactly the sparking module. So, it needs to be changed, and the case with the end.
But if all the signs remained in place, the coil is proper, and other nodes must be checked. But this is a completely different story.
Important! Trying to repair a faulty module, you should not try. It is impossible in conditions of even the most secure service. It can only be replaced. The network has many videos and articles about a certain possibility of repairing ignition coils for Esud. In fact, it is not worth risking. As a result, you can burn brains.
Who produces ignition coils for "priors", what better to take
The main manufacturer of these parts is the German brand firm "Bosch". Although the Russian and Chinese counterparts are already in full volume in the market. We must admit that quality from Germany, of course, is difficult to win. But russian manufacturers, try to approach him as close as possible. Well, about Chinese goods are told too much to repeat it here. In general, if you succeed, it is better to take the "Germans". Well, domestic in second place.
Replacing sparking "Priors"
In essence, this operation is described in the Diagnostic section. So it is necessary to just unscrew the fastener, a bolt for 10. Disconnect the connector. Extract the old, and insert a new module. And that's it. You can go. Just do not forget to call for diagnostics to clean the memory of the ECU from the accumulated errors. That's all.
