FIELD: internal combustion engines.
SUBSTANCE: invention can be used in the internal combustion engines. Engine system comprises first group of outlet valves (8), second group of outlet valves (6) and first and second devices (70) and (72) for reducing toxicity of emissions. First group of outlet valves (8) is connected by fluid medium with outlet channel (74) upstream of turbine (164) of turbosupercharger. First device (70) for reduction of toxicity of emissions and second device (72) for reduction of toxicity of emissions are located in outlet channel (74). Second emission toxicity device (72) is located downstream of the first emission reduction device (70). Second group of outlet valves (6) is fluidly connected to intake channel (28) and outlet channel (74) between first and second emission reduction devices (70) and (72). Invention discloses versions of described method for engine.
EFFECT: technical result consists in reduction of flow of hot exhaust gases to turbosupercharger compressor with simultaneous preservation of possibility of blowing.
