FIELD: internal combustion engines.
SUBSTANCE: invention can be used in the internal combustion engines. Method for a supercharged engine comprises the following steps. Direction of part of compressed air from compressor through throttle valve to engine. Discharge of compressed air from the throttle valve through the recirculation valve to prevent reverse flow of this part of compressed air back into the compressor. Reverse flow of compressed air part into compressor causes surge of compressor. Discharge of the compressed air additional part in response to the throttle valve position change is greater than the threshold change. Part of compressed air is discharged relative to design value of air flow through throttle valve. Disclosed are a method for a supercharged engine and a system for a vehicle.
EFFECT: technical result consists in reduction of noise, vibration and non-smooth operation of compressor due to increased margin by surging at all operating conditions of engine.
