Periodically, motorists have the need to repair the engine of the car. But it rarely comes to the overhaul of this mechanism. Most often everything is limited to preventive work and elimination of minor defects. The preventive work with the engine also includes its flushing. This procedure will be discussed in the article. They also periodically have the need to

The causes of deposits on the surface of the engine are:

products of oil decomposition under the influence of high temperatures;
Wear of the surfaces of parts during operation;
chemical insoluble compounds produced by hard operation of the vehicle engine.
Such deposits gradually accumulate under the hood of each car. The task of the motorist is to neutralize their negative influence on quality of work and service life of the car. The engine oil, which includes additives that clean the inner surface of this mechanism, comes to the rescue. True, it is necessary to remember that the oils of dubious quality or unsuitable for the given type of an engine will not fulfill the tasks of engine cleaning entrusted to them. And in the worst case, they even increase the thickness of the plaque.

The degree of engine contamination is judged by the waste oil.

To minimize the rate at which deposits appear, follow these rules:

Use a modern machine oil of the proper brand, preferably of the SH or SJ grades. Thanks to the latest generation of alloying agents, increased thermal stability and high quality in the raw materials these oils are highly effective in protecting the engine of the machine.
Do not neglect the frequency of engine oil changes. The more often this process is performed, the cleaner the engine walls become, and the less wear and tear occurs. But it is important not to go broke, as oil is expensive. Car-care center workers recommend carrying out such procedure at least once in 10-12 thousand km. run.
Competent adjustment of fuel supply (read more about washing of diesel engine fuel system). Otherwise the enriched fuel mixture will cause rapid growth of sludge thickness in the combustion chamber and blackening of machine oil itself. Pistons, oil caps and other engine elements will be covered with deposits, which will lead to accelerated wear of the whole mechanism, increase of oil consumption and other troubles.

If you realize that you already need to flush your engine, you will need flushing oil or detergent additives. Washing oil contains an increased number of detergent agents. It is only poured into the engine after the used engine oil has been completely removed. To start the engine cleaning process, idle the engine for 5-10 minutes. After that the flushing oil is removed and fresh engine oil is poured into the engine (the oil filter is changed).

In the case of a detergent additive, it is added to the old oil before changing it. After 10 minutes of idling the engine, the used mixture is drained and new oil is added to the engine.
