FIELD: engines.
SUBSTANCE: invention can be used in control systems of internal combustion engines (ICE). Disclosed is a method of operating a drive unit with petrol engine (1) and an exhaust gas cooling system. According to method of combustion air is supplied to cylinder (3) of petrol engine (1) through inlet valve is compressed with by turbo-compressor (12), which has turbine (13) with variable geometry of vanes. Inlet valve closes before piston reaches cylinder (3) of lower dead point. Exhaust gas supplied to turbine is cooled in portion of exhaust pipe, in particular in exhaust manifold. Also provided is a drive unit for carrying out disclosed method and a vehicle.
EFFECT: technical result is high engine efficiency.
