METHOD OF CLEANING OF INTERNAL COMBUSTION ENGINE WITHOUT DISASSEMBLING, CLEANING AGENT FOR CLEANING ENGINE FROM SIDE OF FUEL SYSTEM AND CLEANING AGENT FOR CLEANING ENGINE FROM SIDE OF OIL SYSTEM

FIELD: transport engineering; internal combustion engines of automobiles of different application. ^ SUBSTANCE: invention relates to servicing of internal combustion engines, particularly, cleaning the engines from carbon caused by incomplete combustion of fuel, and it can be used for restoring operating parameters of engine. Proposed engine cleaning method includes its cleaning from side of fuel system by additional of cleaning agent containing neutral ethers of o-phosphoric acid and neutral ethers of boric acid to fuel and delivering said mixture into operating engine, and also cleaning of engine from side of oil system carried out simultaneously with cleaning of engine from side of fuel system or direct before or after cleaning of fuel system by additional of other cleaning agent including mixture of mono-and triamines in equal amounts and butanol and gasoline, preferably, low octane number, to oil and provision of operation of engine for time sufficient for complete cleaning of cylinder-piston group and with subsequent replacement of oil. ^ EFFECT: restoration of operating characteristics of engine owing to complex cleaning of engine at possibility of reliable checking of results of cleaning. ^ 4 cl, 4 ex
