FIELD: chemistry.
SUBSTANCE: antiadhesion coating is deposited through a working medium - petrol fuel for 1-3 hours with composition consumption to 1-5% of the weight of fuel. The antifriction composition contains the following, wt %: esters of perfluoropolyester acid with molecular weight 1200-1400 75…85 and a dispersing agent - non-ionic surfactant 15…25.
EFFECT: method enables to obtain antiadhesion coating on components of the exhaust system of a spark-ignited internal combustion engine with dismantling, reduces the amount of deposits in the exhaust channel and increases reliability of the engine.
