FIELD: mechanical engineering.
SUBSTANCE: according to invention, proposed engine operates on two cycle principle. Engine contains at least one cylinder, at least one exhaust valve and at least one scavenging valve, and compression part which can be made in form of separate compressor, for instance, screw compressor. According to invention, scavenging valve opens after turning of crankshaft through 120° after BDC and closes 30° before TDC. Scavenging air pressure is 3-15 bars. Exhaust valve opens 60° before BDC.
EFFECT: increased effective efficiency.
