FIELD: engines and pumps.
SUBSTANCE: claimed system comprises gas pressure control valve, and intake-exhaust valve to allow intake at one position at opposite position. At intake, control system opens the gas pressure control valve while intake-exhaust valve is set to intake position. At exhaust, control system opens the gas pressure control valve while intake-exhaust valve is set to exhaust position. Control system traces the ICE pistons current position to define opening and closing moments for every valve in compliance with load at ICE. Said system sets the valve control slide valve to position whereat gas is fed from the drive system pneumatic accumulator into the valve drive piston chamber to be actuated. Used gas flows from opposite chamber of appropriate valve into compensating pneumatic accumulator, then, into pistons of the compressor driven by air or mix at compression stroke, or by combustion products at expansion stroke. Compressed gas charges the pneumatic accumulator.
EFFECT: higher efficiency of gas exchange.
