Background

The lubricating oil is subjected to high-temperature and catalytic action of various media and metals through high-speed running in the running process of a vehicle, and gradually deteriorates and ages to generate carbon deposit, a paint film, oil sludge and the like, and is specifically embodied as follows: metal shaving generated by metal friction in the running process of the engine; water stains and dust intruding from the air; water and carbon slag generated by gasoline combustion enter the engine oil disc along the cylinder wall; colloid generated by polymerization of engine oil at high temperature; sulfur, nitrogen and other elements in the engine oil, and oxides generated after combustion become acidic substances and the like when meeting water.

The existence of oil sludge and carbon deposition causes the great weakening of the fluidity of engine oil, and leads the abrasion of an engine during cold start to be more serious, and the cold start abrasion is one of the major abrasion sources of an automobile. In addition, the poor heat dissipation enables the engine to be continuously high in temperature, oxidation and deterioration of engine oil are accelerated, and oil sludge and carbon deposit attached to an oil duct pollute new engine oil.

Therefore, the regular cleaning of the sludge in the engine is one of the indispensable projects for the conventional maintenance of the automobile.
