FIELD: internal combustion engines.
SUBSTANCE: group of inventions relates to the field of internal combustion engines with supercharging. Essence of inventions consists in the following: optimized angular speeds of the engine gas distribution, namely: inlet valves - opening 0–1° after TDC, closing 20–30° after BDC, high pressure release valves - opening 20–30° to BDC, closing 10–20° after BDC, low pressure outlet valves - opening 0–10° to BDC, closing 1–2° after TDC. Design of the turbine allows excluding backpressure to exhaust gases arising from centrifugal force in the turbine. Device for pumping exhaust gases from engine exhaust path is compactly interlocked from turbine housings, compressor and vacuum pump.
EFFECT: technical result is to increase the power of internal combustion engines.
