FIELD: engines and pumps.
SUBSTANCE: proposed system comprises turbine 2, compressor 1, gas feed channels 3, inlet manifold 10, off-gas bypass valve 3 with pneumatic element 6, supercharging air bypass channel 9 with bypass valve 8, supercharging air cooler 4 and control unit 15. Temperature and pressure gages 11, 12 are connected to 1st, 2nd, 3rd, and 4th inputs of control unit 15 and arranged in inlet manifold 10 as well as fuel feed member position indicator 13 and crankshaft rpm transducer 14 mounted on engine. Supercharging cir bypass valve 8 and solenoid valve 7 are connected to control unit outputs. Said solenoid valve 7 controls the feed of supercharging air in above-membrane chamber of off-gas bypass valve pneumatic element 6.
EFFECT: perfected operating performances.
