Description

The invention relates to the field of industry, namely, to the operation and maintenance of equipment and can be used to extract mechanical wear products from internal combustion engines.

Engine wear products significantly affect its performance, the state of friction pairs, the purity of oil channels and, finally, its service life.

The prior art such a method of cleaning engines from wear products patent RU 2127816 C1. Cork of the car’s oil sump “When the device is in operation, metal parts and particles that are in the oil adhere to the cylinder of the magnetic separator and the oil is cleaned of these harmful impurities, thereby extending the service life of parts and components of the car.”

The disadvantage of this method is the partial removal of wear products from the engine, since the magnet attracts only iron wear products, while others remain in the engine.

Known another method of cleaning the engine from wear products "Device and operation of internal combustion engines." A.V. Kuznetsov. Moscow. High school. 1984. p. 151-152: for flushing the lubricating system, special flushing devices and apparatuses are used, which repeatedly flush the fluid through the crankcase and oil cooler over a period of 15-20 minutes.

The disadvantage of this method is the increased consumption of materials and complexity. The basis of the invention is the task of creating such a method of extracting wear products from the engine, which would remove all mechanical particles that threaten the health of the engine, prevent its breakdown, increase engine reliability.

This problem is solved as follows: a method for extracting wear products from an internal combustion engine, comprising removing the filter after its operation from the engine, which is characterized in that the extraction of wear particles is carried out in an oil filter capsule formed by the surfaces of the main filter element, the filter element of the bypass valve and the shell oil filter.

If a conventional filter without filter element of the bypass valve is installed along the oil flow path, the mechanical wear products pass through the bypass valve and are distributed throughout the engine oil system (in the oil pan crankcase, oil channels, etc.), which makes their collection very difficult . To extract these wear products, it is necessary to disassemble the engine and flush out the places of their possible accumulation.

In the capsule of the oil filter formed by the surfaces of the main filter element, the filter element of the bypass valve and the shell of the oil filter, when removing the oil filter, all hazardous mechanical particles are removed from the engine.

Such an oil filter during operation does not release a particle that enters it.

The technical result consists in the ability to remove all mechanical wear particles that threaten the performance of the engine when removing the oil filter.

A causal relationship between the essential features of the invention allows to obtain a technical result, indicated in the statement of the problem.

According to the applicant, a combination of features characterizing the essence of the invention of the unknown from the prior art is proposed, that is, the invention meets the criterion of "novelty."

The invention is illustrated by an example of its implementation. An oil filter is installed on the engine, comprising a main filter element and a filter element of the bypass valve. When the engine is running, the oil filtration process begins. During engine operation, the filter accumulates mechanical particles without releasing them from itself. When the filter is removed, all mechanical particles are removed from the engine that pose a threat to the engine’s performance - these particles are much larger than the gaps of the friction pairs (three or more times) that were sent to the engine through the oil pump.

The essence of the invention does not follow explicitly for a specialist from the prior art, therefore, the proposed method meets the criterion of "inventive step".

To date, this method has not been removed mechanical wear products (particles) from an internal combustion engine.

This invention can be carried out in an industrial environment.

Using the proposed method allows timely removal of all mechanical particles that pose a threat to the health of the engine.

Thus, the proposed technical solution meets the criterion of "industrial applicability".
