The engines collected after repair are running and tested on special stands. Purpose Obraktka - the advancement of rubbing surfaces and identifying defects resulting from the deviations allowed when repairing deviations from technical requirements. In the process of running, the final adjustments are performed and defects are eliminated. The purpose of the test is a comprehensive assessment of the quality of engine repair.
If the repair of a diesel engine was carried out without removing from the tractor and was replaced by one or two sets of the cylinder-portion group, in repairing the cylinder heads or replacing the liners of connecting rod bearings, then it is rolled out without a load of 5 minutes on each of the crankshaft rotation frequencies: 800-1000, 1400 - 1600, 1700-2100 min-1. Behind the rotation frequency of the crankshaft is monitored by a tachospideometer or measured by a tachometer.
When the diesel engine is opened, the oil pressure and coolant temperature is monitored. Check the air seats in the places of inlet pipes. At the end of the cycle, the run-in is checking the maximum rotation frequency of the crankshaft at full fuel supply.
After running, the nuts fastening the cylinder head fastening the dynamometric key and adjust the gaps in the valve mechanism. Check and, if necessary, adjust the fuel injection advance angle, tension of the drive belts.
The occasion of capital engines on the stands is carried out in several stages:
- cold running (from electric motor)
- hot without load (idling)
- with variable load
After running on the same stands, engines are carried out.
Cold running
At the cold run-in stage, a number of technologies use a number of technologies.
Mul-visual oils are used, such as industrial and-20a or and-zoa, a mixture of industrial oil and-20 and motor MG-10-B2. Additives to oil (colloidal sulfur 0.9-1.1%, Molybdenum disulfide, metallometallic additives based on copper glycerat OMP-2 - up to 15% by volume of oil, etc.); Om-2 special ripping oil is used, the additive of DK-8 and others is introduced into the oil. At the same time, the run-in time is reduced by 1.5-2 times, the metal from the surfaces of the parts decreases.
Run through and test motors depending on their power on the electrose stands of KI-5542 (37 kW), KI-5541 and KI-5543 (55 kW), KI-5540 (90 kW), KI-5274 (160 kW), Ki- 5527 (for starting engines). These stands allow you to scroll through the crankshaft of the engine with a variable frequency during a cold run, and when hot returned with electricity into the electrical network.
Cold running mode is installed by technical requirements for motors of each brand. For example, D-240 engines run on motor oil for 30 minutes - 10 minutes on each of the three steps with a crankshaft rotation frequency of 500-600, 700-800 and 900-950 min-1; The D-160 engine is running 55 minutes, of which 15 min at the rotational speed of 400- 450 min-1 and 40 min at a rotational speed of 900 min-1. Cold running of launchers and carburetor engines is carried out for 20 minutes.
In the process of cold rolling, they check the heating of rubber surfaces to the touch, listening to the engine inside the engine, determine the tightness of the compounds, control the pressure and temperature of the oil. In case of malfunctions, the running is stopped and eliminated. If necessary, the engine is sent to repaired.
Hot run without load
After the cold running of the electric machine, the engine is allowed and run through it according to the mode established by the technical requirements, first at the reduced rotation frequency of the crankshaft. For example, the D-240 engine is rolled over for 20 minutes, of which 5 at a speed of 1000 min-1, 10 minutes at a speed of 1400 min-1 with a smooth increase of up to 1800 min-1 and 5 minutes at a 100% nominal frequency Rotation. The engine D-160 - 10 min at the speed of 500 min-1 and 10 minutes at the rate of rotation 1300-1340 min-1. During this run, the same checks are carried out as when cold, and, moreover, check the action of all mechanisms, adjust the gaps in the valves, the ignition (for carburetor engines).
Hot running under load
With this run, the power machine operates in the AC generator mode and simultaneously serves as the engine loader. A working diesel is loaded with full fuel supply at the corresponding modes. Load modes are determined by the technical requirements for each Diesel brand. For example, diesel D-240 is running for 80 minutes on six stages of loading (kW): 10 min - 5.9; 10 min - 14.7; 15 min - 21.1; 20 min - 35.3; 20 min - 42.7; 5 min - 47.8. Diesel D-160 runs up 50 minutes on six steps with load (kW): 10 min - 22-44; 10 min - 14; 12 min-92.5; 5 min - 110; 3 min - 118; 10 min - smooth decrease to zero. In the process of running, the oil pressure is monitored, the engine is dried, and, if necessary, stop the running and eliminate the malfunction. Unlike diesel engines, carburetor engines begin to run under the load at the speed of rotation of the crankshaft 1200 min-1. With increasing load increase the frequency of the shaft rotation.
Accelerated engine running
At repair enterprises, an accelerated runoff of diesel engines on fuel with an Alp-4d additive, which is as follows. 1% (by weight) of the elementodorganic additive Alp-4d is added to the expenditure tank of the stand. Stirring the fuel additive provides a mixing and dosing device of the KI-11138A. When combustion, fuel additives in the cylinders are formed solid aluminum oxide particles with a size of 2-3 μm, which accelerate the acquisition of parts of the cylinder-piston group and reduce the time of the technological runoff by 30-35%.
Apply the technology of accelerated runoff using a constant electric current. The engine installed on the stand is subjected to a cold run for 10 minutes at a crankshaft rotation frequency of 500-600 min-1. Then the minus terminal of the source is attached through a special current collector of the KIu-11041m device to the crankshaft, and the plus to the cylinder block. At a current of 3-5 A and voltage of 0.8-1.2 V, the cold run is continued for another 25 minutes at a rotation frequency of 900-1000 min-1.
The hot engine run without load is carried out for 15 minutes at a rotational speed of 1300-1400 min-1. The load under load is carried out for 20 minutes: 10 min with a load of 20% and 10 minutes with a load of 50% of the nominal. As a result of the accelerated accuracy of rubbing surfaces when the DC pass through the friction pairs, the engine running time is reduced almost twice.
Engine test
Each capitally renovated engine is subjected to acceptance tests. At the end of the running, the engine operating at the maximum rotational speed of the crankshaft at idle is smoothly loaded to obtain the rated speed of rotation and write the testimony of the weight mechanism of the stand. The efficient engine power is determined by the formula:
NC \u003d 0.736 PN / 10000,
where NC is the efficient power of the engine, kW; P - indications of the weight mechanism of the stand, H; N - Engine crankshaft rotation frequency, min-1
When testing on a stand with a gearbox, the efficiency of the gearbox is taken into account, n \u003d 0.98. Full load is prohibited to load the engine for more than 5 minutes.
At the same time control the oil pressure in the engine highway and the fuel consumption is determined. An hourly fuel consumption is determined by the formula:
GT \u003d 3.6 Q / T,
where GT is an hour consumption of fuel, kg / h; Q - mass of fuel, and spent during the experience, g; t - the time of experience, with
The specific fuel consumption is determined by the formula:
gC \u003d 1000 GT / NE,
where GC is a specific fuel consumption, g / (kW * h)
The power and fuel consumption obtained as a result of the engine tests lead to the values \u200b\u200bof the standard test conditions:
- environmental ambient temperature 25 ° С
- air pressure 0.1 MPa (760 mm Hg)
- relative air humidity 50%
- fuel density 0.82 g / cm3
After testing, a partial or complete engine inspection is carried out. A partial inspection is subjected to each engine SDM-60, YAMZ-240B, YMZ-238NB, D-108 and D-160 and one of the ten engines D-240, D-65, D-21, complete inspection - every 50th engine. With a partial inspection, the pallet is removed, opened and inspect the lower liners of the native bearings and the shaft neck, inspect the cylinder sleeves mirror. With a full check inspection, the cylinder head is revealed to open the root and connecting rod bearings, take out pistons with rods and determine the quality of the running of the driving surfaces of the parts.
When buying a new machine, it is necessary to run it up to insert the details of the mechanism and prevent their premature wear and the occurrence of deformations. Every driver knows, although in recent times more and more automakers assure that the procedure is not needed.
There is another situation - running the engine after a side repair, in which the components and aggregates of the mechanism also need to be wrapped.
What is the engine running and why is it necessary?
Engine run-in is its operation in a gentle mode in "field" conditions or imitation of work on a special stand. The goal is one - complete trigger of all elements. The engine running after the overhaul makes it possible to fit the parts to each other, ensuring their operation.
Even a qualitatively performed replacement of spare parts does not give an accurate landing of details, as in the factory conditions when assembling. In addition, the replacement can be partial - at the same time old parts are worn or have changed parameters. The new element must be fitted under the old one.
Three main reasons for rolling the engine:
- Pistons in KBS have special recesses in which piston rings should "sit". This happens when the motor is working in sparing conditions. If you neglect the procedure, the rings can simply break down, which will output the engine. To the occurrence of breakage very often leads a sharp start.
- In the process of running the load, the friction of parts is constructed by each other, which leads to the formation of metal chips in oil. The latter must be changed, removing with it and foreign metallic impurities. The chips, affecting the details of the mechanism, very quickly leads the motor system into disrepair.
- No matter how well the piston has been processed, there are probably microscopic irregularities on it. With gentle operation, they are leveling.
Motor running varieties
There are several types of engine running.
Cold on stands
It is performed on special equipment in workshops using a cardan shaft, which connects the autonomous electric motor and the shaft of the car engine system. The electric motor drives the engine of the machine. The intensity of rotation The wizard is set using an encoder, and the process itself controls the computer by setting the pace of rotation according to the data obtained.
However, the stand is not in every workshop, so you have to resort to other ways.
Cold without stand
You can run a "easy" run. An oil is poured into the engine, the radiator is needed toosol or antifreeze. The bay of techity, the car is simply moving around 2 hours on the site, not including the motor.
When conducting a wipes, the temperature of the motor plays an important role. At the stations, the temperature control is monitored with oil and hot water.
Hot running
This method of running can be used at home. It will be necessary to start the car engine and bring the speed to the level of its work at idle. The motor should work for no more than three minutes. Then it is worth a break and wait until the motor cools. You need to repeat the procedure several times.
Motor must be started and left in a working condition for 50 minutes. It should be started with a 1200 rpm and slowly bring the value to the middle of the permissible. If the engine overheats, it should be drowning and cool.
By producing a hot run, it is worth checking the oil and the state of other technical fluids, to make sure the tightness of the compounds and control compression.
Running in vivo
The engine is simply operated in a gentle mode - no excessive loads, sharp starts, braking.
First launch after "Capitals"
The initial mileage of 3,000 kilometers is considered the most important - precisely at this time the motor is maximally exposed to adverse factors.
Filter must be carried out carefully. When the car passes the first thousand kilometers, you should replace the filter and engine oil. It is better not to use various additives and other additives. Prefer pure oil.
To run the engine after overhaul correctly, you should follow a few simple rules:
- not to abuse when driving too high or low turnover;
- do not ride a fixed speed and with the same number of revolutions - these indicators are better to vary;
- do not apply the engine braking - the run-in mode is not suitable for this;
- it is forbidden to tow trailers or transport in the luggage compartment of goods;
- you can not sharply accelerate or brake.
Before starting, getting ready for running
Before making the first start of the engine after repair, you must prepare a car to the running-in procedure. Otherwise, the power plant may not get proper wreck, which will reduce its service life.
First, you need to fully charge the battery. The initial launch is of paramount importance - the crankshaft turnover is too tight, the load on the battery is large. It is impossible to allow the battery to fail during the first launch.
Secondly, oil filter and oil itself are subject to mandatory replacement. It is important not to wet the filter element in the oil mixture before installing, otherwise an air stopper may form.
Many motorists are concerned about how to properly run the engine after overhaul. There are some features that often ignore drivers.
The first 3 thousand km should not exceed the speed of 50 km / h. During this time, the motor will host a primary wipe. Finally, everything will come back to the reach of 10,000 km. So long to drive at a speed of 50 km / h is unlikely to seem possible, but it is not recommended to even exceed the speed of 100 km / h and subject the car with excessive loads.
After that, the car will be ready for full operation even with large loads. After 5,000 km of run, we should change the oil and pour the recommended automaker.
Diesel running features
Obtaining a diesel engine after a overhaul does not have extinguishing differences from a gasoline engine running. The focus should be focused on the pressure of the oil in the system (the oil pump delivers lubricating fluid into the unit and creates the necessary pressure). Operate the vehicle is better at minimum loads.
If the car is planned, then you should not ride 4-5 transmissions. Punked the car follows the city, on a flat high-quality track. It is also not recommended to give a batter car - it does not affect the operation of the mechanism. The engine is desirable to warm up to the XX, and then bring to the working temperature mode.
What should not be done?
Overhaul of the motor - stress for the car. And pass the engine running by the rules:
- You can not ride a bumpy road, where many slopes.
- You should not overload the car by passengers.
- You can not operate the motor with the same load constantly - change it.
- It is not recommended to change the load sharply - all manipulations should be carried out smoothly and gradually.
- You can not accelerate when running the car over 60 km / h.
A properly run-in engine will serve his owner long. The main reasons for the rapid wear of the power unit are that some drivers do not know how to run the engine correctly. But spending time to study this procedure and performing it correctly, you can save the car in a proper working condition.
When buying a new car, the question arises, how to ride the engine correctly, so that it does not have any problems and is it necessary to run a contemporary engine? There are many myths and legends with which we will try to figure out.
Exposing myths
1. Turns. In no case should not spin the engine above 2500-3000 revolutions, since the engine is not yet rolling.
This legend has taken from the time of the Zhiguli, when the items were processed on not entirely accurate equipment, hence both the increased requirements for the latch of parts. Modern engines are treated on high-precision machining centers that create a microrelief on the surfaces of parts, allowing the engine to work almost without running. In addition, the "cold run" is made on the factory before installing the engine on the car. The turnover can be twisted and 4000-5000, the main thing is not to give large loads to the engine.
2- Many recommend not to ride in high gears. Again, many incorrectly interpret it. If you do not load the engine, then the motor without a difference, which gear is turned on at the same load. For example, go on the fifth gear from the slide and on the slide is completely different load, in the first case the machine will roll myself, and the engine will only slightly push, then in the second case, the load will be increased.
3- run the engine is recommended in the warm season. Larger nonsense is difficult to present, but heard repeatedly. What then to do those who buy a new car in winter? Wait thaw or still ride? Although in the frost -30, any engine starts problematic, and the run-in does not affect it.
4- Do not ride around the city. The first few hundred kilometers recommend to operate the car outside the city, so as not to twitch between traffic lights. Some believe in it.
The car is designed to ride it in the city, and the acceleration-braking does not create some critical loads to worry about it.
Reality
And now we turn to the algorithm for the correct engine running.
The main thing is that it is not necessary to do is load the engine. If you eat at a speed of 100 km / h at the 5th gear, and you suddenly have a cool slide, you do not need to immediately turn on the reduced one. But when the car stops "pulling out" - then it is necessary to include low. And revolutions, with 2500 revolutions, you will not leave the slide, too much load on the engine, the machine goes into the dash, since the torque on the data turns is not the highest. It is better to add gas and accelerate in advance or reduce the transfer, but add speeds. 2000-4000 revolutions per minute-normal operation of a new engine, as the highest torque develops in this range. Cars with an automatic transmission themselves regulate the load on the engine and maximum speed, so you can simply press the gas and especially not to think about what is happening.
Most manufacturers do not impose any requirements for the engine running, stating that the factory run-in is enough for subsequent normal operation. But at the same time, an increased oil consumption is possible when running, which after several thousand mileage is normalized.
The process of accuracy of parts
In any mechanism, drunk parts are wearing, and the wear process has three stages:
- Period of partings of parts
- Period of normal wear (all subsequent operation)
- The period of limit wear
Officon is the period of partings of details, it is during this period that the maximum wear of the parts occurs when the running parts acquire the relief of the response part. At this time, the maximum amount of wear products is falling into the oil, which clog oil. That is why it is not necessary to tighten with the first oil change.
Many motorists are familiar well with the fact that after purchasing a new car or overhaul, the engine must be rolled out properly. Immediately note, competently executed running time allows 15-20% by 15-20%, increase its pickup and efficiency.
There are several types of run-in, among which the most commonly found "cold" and "hot." In the first case, the electromotor is connected to the engine, which rotates the unit without starting it. This is a cold run. As for the second type, the engine runs right on the machine, that is, in motion.
As a rule, the overhaul of the motor in many services does not imply a cold run, as far from all the hundred have special stands for the specified procedure. This means that rushing the power unit will have to the most car owner. To do this, you need to know how to run the engine after the overhaul.
Read in this article
Features of the correct engine run
Let's start with the fact that you should not confuse the concepts of overhaul and engine bulkheads. The bulkhead involves only certain narrow operations (for example, valves, gaskets, etc.).
Overhaul means that a complete disassembly is performed, washing, defecting and replacing all worn items, as well as fit under the factory parameters. The list of operations is usually located, replacement of pistons and piston rings, installing new and more.
Such a repair is expensive and carried out exclusively by profile specialists. As a result, the owner receives a fully restored engine, which is approaching most of the characteristics to a new unit.
It becomes clear that both in the case of new and "chicken" DVS ruling rugs will be very similar. The fact is that the installation of new, as well as restored parts after grinding and surface treatment also requires mandatory tickling of all elements for normal and well-coordinated operation of the unit under loads.
How much to run the engine after overhame and how to do it
So, the most important can be considered the first 3 thousand km. During this period, especially in the first thousand, it is necessary to observe the optimal ride mode for the motor, that is, respect for gentle operations with gentle loads. General rules are as follows:
- it is forbidden to ride with high or too low turns;
- it is impossible to drive with constant speed and the same turnover;
- should be abandoned from the carriage of goods or towing trailer;
- you can not use the engine braking, practicing sharp accelerations and stops;
In other words, during running, it is necessary to eliminate the heavy modes of operation for the engine, the load on the unit must be moderate, grow gradually. Also during this period, it is very undesirable to give a motor for a long time to work at idle (except warming up), since the XX is considered a difficult mode of operation of the DVS.
Now let's consider the engine running process after overhaul. First of all, you need to understand that the motor after the overhaul needs all the details and nodes to get along well to each other.
If we talk about fully recovered internal engine, then work is usually affected by the complex. This means that it is necessary to run such an aggregate at least 3 thousand km. If the repair affected exclusively and the GDM (replacement, etc.), then there is enough 1 thousand km. Let us dwell on a more common first version.
- Before traveling, the engine needs to warm up a little on the XX, after which the unit is fitted to the operating temperature in motion.
- Optimally planning in advance the route so that the road is smooth (without frequent lifts and descents). It is also desirable that the car was only the driver.
- During ride, there must not be allowed sharp accelerations and braking, jerks, and also forbidden.
- It is recommended not to accelerate more than 60 km / h, switch to increased transfers and raise the crankshaft turnover above 2.5 thousand rpm.
- Also avoid riding in tension, continuous movement on low revs (1000-1500 rpm).
- You should not allow moving with the same load on the motor. If otherwise, you do not need to go with a constant speed on one transmission. Optimally smoothly dispensing the load, periodically slowing down and accelerating, but it is important to choose the gear correctly so that the aggregate worked within the framework of the average revolutions.
Simple words, this approach allows the piston rings to "stand out" in the piston grooves, gradually begins to "cut down" the mirror in the cylinders, etc. The fact is that even the most careful grinding does not allow you to perfectly smooth all the irregularities that are leveled by the running.
We also add that the generally accepted figure of 3 thousand km. It is minimal. It should be remembered that the complete trigger of all parts and nodes on many DVS occurs to 8-10 thousand km. Run. It turns out, this whole period is also desirable to adhere to the run mode, although not so strictly. Only at the end of the specified segment the engine can be loaded, gradually and smoothly lifting loads from medium to high and then maximum.
Replacing the oil after the motion overhaul
It should be understood that the obligatory result of the wipes of parts (especially in the first hundreds of kilometers) in the engine is a metal chips. The specified chips enters the engine oil and accumulates in the oil filter. It is quite obvious that this chips should be removed from the engine.
This means that it is necessary to use such a material recommended by the engine manufacturer. Lubrication must comply with all standards, requirements and admission of API and ACE, as well as approach SAE viscosity, taking into account seasonality and other regional features.
It is also necessary to separately take into account that after the boring of the cylinder block in the repair dimensions under repair pistons in some cases, experts recommend using more viscous oil compared to the one that is poured into a similar new motor.
The information that is shown below will be useful for those who make the motor overhaul with their own hands or is directly involved in this process.
- Before the first launch and during running, you need increased attention to the state. Consider, during the first launch, the crankshaft is most difficult, so the battery should be.
- Some precautions should be taken during the oil fill and install the oil filter before the first launch. The main task is to eliminate the formation of air traffic jams so that the unit does not experience the unit at the time of the start.
- Lubrication and other liquids need to be poured. The fact is that the excess of the recommended volume can lead to the emergence of currents and other faults.
- After the first launch, the oil pressure must come back in a few seconds during operation on the XX. It is forbidden to gas in the event that. If the oil pressure at idle is low, the power unit must be immediately jammed.
- Then re-launch. If the situation does not change, then the malfunction is obvious. Any problems with oil supply, air traffic jams, incorrect operation of the oil pump and other reasons can lead to the need to re-repair the engine.
- In the event that the pressure of idle is normal, you can warm the motor. With increasing temperature, lubricant is diluted ,. At the same time, it should not fall below 0.4-0.8 kg / cm2.
- While the engine warms up, you need to carefully examine the power unit for leakage of oil, and other technicians. If the leakage is noticeably, the engine is immediately jammed, after which the problem should immediately localize and eliminate.
- If the pressure in the lubricant system is normal, the unit is dry and operates smoothly, then it is also recommended attentively no extraneous noise and the knocks should not be.
Normal and steady work of the engine is suggested that it is possible to start a motor running under load. Take a trial short trip, while observing the oil pressure light in the lubrication system and the inlet temperature in the instrument panel. After 2-3 km. Ways stop the car and again inspect the engine for leaking technical fluids.
Then the power unit should be drowning, wait about 15 minutes and check the level of engine oil. The fact is that he may fall a little. This will require the lubricant topping. It is necessary to top up the oil so that the level is exactly in the middle between the MIN and Max marks.
The stable operation of the engine and all its systems will indicate that the motor after overhaul is ready for further running. For best results and extension of the service life, you need to adhere to the runningout modes and follow the recommendations indicated above.

Engine running - The period of using the car in gentle mode. Required when buying a new machine or after a motor overhaul.
The main task is the trigger of the new engine elements, at low load. This process is accompanied by an increase in the temperature of the motor.
Compliance with the rules of running will extend the life of the engine 3 times.
Types of engine running
Consider popular views.
1. Oclooked engine running with a stand - The most correct way. For it, specialized standing equipment is used, allowing you to quickly and effectively work. It is carried out under full control, which makes it possible to detect faults and inaccuracies at the earliest stage. The characteristics of the engine are controlled by electronics, the stand works on a specific algorithm.
2. Cold running Engine - Attempt to repeat the work of the stand. The car is pulling on a towing cable for several hours. It takes a little time, but without control of indicators, the effectiveness can be judged only in time until another repair.
Signs of efficient cold engine running:
- stable work at idle
- fast and easy launch;
- acquisition of additional power,
- improved car dynamics.
3. Hot running - The most popular way. It takes place at idle, but at different intervals of work. Between the stages of the engine must be completely cool. IMPORTANT! Monitor technical fluids. After this stage, it is recommended to carry out a natural run.
4. Natural running in - The easiest way. Lies in the careful use of the car on the first two thousand mileage.
Requires compliance with certain rules:
- comply with high-speed mode up to 70-80 km / h,
- do not overload the engine, stable operation no more than 2500 rpm,
- avoid sharp overclocking and braking,
- monitor the technical fluids and the temperature of the motor.
Signs of incorrect engine running:
- the oil falls the air cleaner,
- increased fuel consumption and oil
- power shortage
- problems of the first launch.
The first start of the engine
Running the motor is very responsible occupation. Compliance with not difficult rules will facilitate this task.
- The car battery must have a full charge, otherwise he will not be able to move the crankshaft.
- High-quality engine oil is filled to the maximum border. After the fill, it is necessary to wait at least 5 minutes, the oil should fill all empties. In no case, do not pour the oil filter, in order to avoid air traffic jam.
- In the absence of a fuel pump, produce a fuel swap manually.
- When the engine starts, control the oil pressure. If the indicator is on more than 3-4 seconds - urgently shuffled the car before troubleshooting. Deviations in oil pressure signals incorrect assembly (not loyal gaps, oil pump is faulty, low-quality oil).
- With an oil pressure of 0.4-0.8 kg / cm2, warm the engine to 85-93 s, tracking possible leaks of liquids. The smell of Gary and a slight smoke at this stage is the norm, assembly lubricants burn out.
- If necessary, spend a hot run.
Engine running mode after major repairs
At this point, the main thing to adhere to the rules of natural runoff:
- Do not exceed the speed of 60-70 km / h
- Do not include the fifth gear.
- Do not overload the engine.
The most responsible - the first 500 km. Size exhaust smoke - norm, especially when replacing piston rings. Idling regulates after a thousand kilometers of run.
After a run at 2500-3000, the car can be used in normal mode.
Strong engine running mode
- The first 0-50 km move on the third gear at a speed of 40-50 km / h.
- Further 50-150 - on the fourth gear at a speed of 60-70 km / h.
- 150-500 - Fourth Transfer Movement, adding speed by 10 every 100 km. Do not allow aggressive driving, when moving in a hill, include reduced gear in advance, and speed reduce up to 20 km / h to unload the engine.
- 500-1000 - start using the fifth gear at a speed of 100 km / h, not exceeding 120, but only on the smooth straight road. Turns should not exceed 3000 when overclocking and switching speeds.
- 1000-1500 - Turns are increased to 3500 during disks.
- 1500-2000 - the rules are not so tough, the engine can be loaded gradually. Small lifts pass on the fifth gear. When starting from the traffic light, you can increase the speed to 4000-4200, ride from the slide 145-155 km / h. It will be useful before passing.
- By 2000 - to pass. After running, be sure to rinse the engine, pour high-quality oil and replace the oil filter, because metal particles are accumulated in oil, which can cause internal damage. Now you can relax and enjoy driving a car.
