How to ride the engine after overhaul

First of all, it is worth considering one nuance, the power unit, which has been overhauled, acquires the properties of the new engine. Namely, all the details that are involved in mechanical work are not fitted with each other. What causes elevated wear and complex conditions for the operation of the motor. This is due to the fact that each detail, although it is manufactured on high-precision equipment, but still has its own surface structure, thereby causes greater friction resistance. This effect is corrected within some time of work, but to keep the maximum resource of the repaired unit, it is necessary to perform all the rules and requirements of the rope of a new or repaired engine.

Therefore, this article will describe all methods and detailed recommendations for the operation of the engine and the car itself during the first kilometers after major repairs. Following these advice will help maintain the engine performance even more.

Also, it is worth considering the quality of component parts. Naturally, in such a responsible element of the car as a motor, it is worth installing only original spare parts, or knowingly better quality. Otherwise, even competent runoff will not prevent one more repairs in the near future.

This article is designed for newcomers in the maintenance of cars, because, experienced masters are well aware in all nuances of the run-in, and they can advise themselves how to spend it, or hold it on their own on the stands in the workshop.

Motor running varieties

Most often, four types of engine running are applied. At the same time, some methods are available only by specialized maintenance stations, others are used by the car owner.

Cold engine running on the stands;

Cold engine running on their own;

Hot running (used and masters for a hundred, and car owners in the garage conditions);

Natural runoff.

And so, we turn to the description of these methods:

Cold running in stands

This is the most correct and accurate way to last all the new parts in the renovated engine. For this purpose, a special stand is used, which unfortunately has not every maintenance station. But it allows you to quickly and efficiently carry out all the work on the engine run. At the same time, complete control over the operation of the engine and all possible malfunctions or inaccuracies in the operation of the power unit are found and corrected at an early stage.


Cold tick, this method is called due to the principle of work of the stand. By installing the motor into a special place, its crankshaft is connected to an electric motor, which will be involved as an element transmitting torque to the crankshaft. Next, the engine is flooded with a good quality automotive oil and the cooling system is connected. Turns and characteristics of the motor operation are controlled by electronics, which eliminates most random errors in the wipe, since the entire stand works on a predetermined algorithm.

Cool runout without stand

This method is most likely an attempt to repeat the principle of work of the stand device. Based on the fact that the motor is faster, if it does not heat up from using gasoline or other fuel, and rotation is attached by external devices.

The whole principle of this method is very simple. The car is cling to towing cable for another and pull it on the third transmission included within a few hours. It helps to run the engine running faster, but excludes any control over the process and compliance with various algorithms. And the success of the procedure can be judged after some time, on the running range until the next repair.

But there are several ways to determine the success of the car running, and when using a cold way, these features are especially noticeable:

The engine begins well and stably keep speeds at idle. And their number per minute does not exceed the standard for your motor;

The engine begins to start much easier;

The car received an additional increase in power and dynamic characteristics.

Hot engine running

This is one of the common ways used in engine repair workshops and experienced car owners. Sometimes, it is applied paired with a natural run. The process itself is performed at idle, but with a different number of engine speed per minute and with different intervals of its work.

To begin with, the engine starts at a short period of time (up to three minutes), but this procedure is repeated several times. At the same time, between the stages, the motor should cool, otherwise, you can get point overheating of parts in friction places.

After the short launch cycle, which allow you to carry out a quick or primary feeding of parts, the engine starts for one hour. During this hour, the motor turnover gradually increases, at the end of the procedure, the rotation of the motor should not exceed half of the maximum permissible for this unit. For the entire procedure, it is necessary to monitor the motor temperature, and if it is increased above the norm, it is immediately drowning out the engine, and after cooling, repeat the process from the beginning. Also, it is necessary to monitor the level of oil and coolant, and carefully check all the connections and gaskets on the possibility of leakage of technical fluids.

Now we can assume that the engine running after major repairs - ended. But it is worth noting that it is recommended to go through a natural run-in - this will give a guaranteed result of a full-fledged wipging of all elements of the engine.

Natural engine running

This method is the simplest, it consists in the neat operation of the car for the first 2,000 mileage kilometers. At the same time, the car owner requires only an excerpt and compliance with the elementary rules.

During the natural run, which is recommended not only for cars with an engine after a major overhaul, but also for new cars from the conveyor. For the first 2,000 km of run, you should not overclock the car above 70-80 km / h, and the number of crankshaft revolutions per minute is not desirable to exceed the level of 2,500. This will allow the engine in a gentle mode to invert all the details, and the driver will not "mess around »With a car in the garage.

Also, you should not sharply overclock the car to the recommended speed, carry out braking by the engine and overload the car. And also, it is necessary to constantly monitor the level of automotive oil, the temperature of the motor and the amount of coolant. After this procedure, the car can be fully used.

It is worth remembering that at the time of the engine running after major repairs, a new engine oil and an oil filter are used. After all necessary procedures, it is necessary to rinse the engine, pour new quality oil and put a new oil filter. This is done because, after ticking all the details. In oil, small particles of metal appear in oil, which for long-term operation can score thin oil channels and work as an abrasive material.

Even after the end of the engine running, it is necessary to carry out a technical inspection concerning all important engine nodes, which include checking the gas distribution belt, the generator belt and other elements.

Output

After studying information, one can make the only correct output, engine running in the engine is an integral part of the engine overhaul, which is required. This stage will allow you to save the engine resource and increase the technical specifications of the car.
