FIELD: engines and pumps.
SUBSTANCE: piston engine comprises engine control system and valve timing phase variation system. Intake pipe houses blow valve while cylinder accommodates intake and discharge valves driven by camshaft. Blow receiver is arranged between blow valve and intake valve. In compliance with this invention, blow valve is opened by partial or complete displacement of throttle driven by common armature of several electromagnets in response to engine control system and valve timing variation system instructions, while intake and discharge valves are driven with no part of valve timing system. Note here that intake valve opens before blow valve to communicate combustion chamber with blow receiver but closes after, before or at a time with blow valve after BDC of intake stroke.
EFFECT: improved operating performances.
