FIELD: internal combustion engines.
SUBSTANCE: invention can be used in the internal combustion engines. Supercharged engine control method includes the following stages. Throttle valve position adjustment of the air intake system when the oil dilution degree in the engine is higher than the first threshold value and the oil temperature in the engine is below the threshold temperature. Creation of rarefaction. Creation of rarefaction in casing for improvement of fuel evaporation from oil in engine. Disclosed are a supercharged engine system and a supercharged engine control method.
EFFECT: technical result consists in reduction of degree of dilution of engine oil with fuel without need to increase temperature of oil in engine.
