FIELD: engine building.
SUBSTANCE: invention can be used in control systems of supercharging devices for internal combustion engines. Disclosed is a method for a supercharged engine, which includes the following stages: the second compressor is bypassed by air and a compressed air flow is fed into the piston engine through the first compressor. In case of reduction of required engine torque, second compressor rpm is increased and the amount of compressed air fed into engine is decreased.
EFFECT: technical result consists in reduction of surging probability without reduction of engine with supercharging efficiency.
