Break-in engine

Many motorists, due to their inexperience or impatience after major repairs, immediately strive to check how much their car has become more powerful. This is the greatest mistake that a car enthusiast can tolerate in relation to his "iron horse". Even the smallest repair takes most of the power of the car engine, and to return it, will have to wait.

What is engine break-in? Engine rolling is necessary in several cases - if the car is new, if it is only from overhaul, if it has been idle for a long time. And remember that the car that just left the assembly line, run faster and easier than repaired.

The purpose of the article is to give an answer to the question of how the engine breaks in after repair. Let us consider this in more detail. To do this, you first need to find out why the engine is running at all. When the internal combustion engine is overhauled , the parts that have failed are replaced. Right? The surface of new parts always has unevenness at the microscopic level, which are beyond the human eye. This is where the engine breaks in. It is designed to make the new details "friends" with the available workable ones.

Unlike the car, which left the conveyor, the process of running in a repaired engine is of a different nature. The basis for a successful passage of the procedure is the engine running for many hours idle to pass the first stage of running in. After the initial stage, the internal combustion engine needs 2-4 thousand kilometers to operate in a scrupulous mode. Do not allow heavy loads, drive at low or medium revs.

Run-in engine after major overhaul should pass evenly. On the first few thousand kilometers in any case, you should not allow sharp jumps in turns. Nevertheless, sudden acceleration and braking are simply unacceptable for a new engine. Conclusion: it is better to carry out these procedures on a free route than in a city where sharpness and attention often become a departure from an accident. Also, avoid running the engine in difficult road conditions (dirt, snow, etc.).

Engine break-in in each situation on the time frame occurs in different ways. Usually it is 5-10 thousand kilometers. Many motorists try to pass this period as quickly as possible. And many of the same motorists simply do not know that the new parts overheat faster, and with a long engine running, the quality of the running-in is significantly reduced.

Beginners and motorists with experience, remember that the proper running-in of the internal combustion engine will significantly prolong the period of effective use of the car, without losing valuable minutes for unscheduled simple and repair. And the further power that will return during the break-in will depend on how carefully the new parts "rubbed" against each other.
