FIELD: engines and pumps.
SUBSTANCE: invention relates to control recirculation of internal combustion engines (ICE). Invention consists in that the device comprises a control system, a gas distributor composed Two valve timing and valve stem connection inlet and outlet valves. Control system in accordance with the defined current capacity of the engine determines the mass of the exhaust gas for combustion. When the piston engine from the bottom dead center on the exhaust stroke in the vicinity of the upper dead point in time when the in-cylinder engine will have some system of control mass of the exhaust gases, the system sets the linked rods inlet and outlet valves to the position at which the inlet valve is open, and the exhaust valve is closed. As a result, part of the exhaust gas remains in the cylinder, and at a subsequent suction stroke, or the air fuel mixture remaining in the cylinder exhaust gases are mixed with incoming air to the cylinder or the fuel mixture. Valves are actuated by pneumatic system with pneumatic accumulator charging gas from the engine combustion chamber and the compensation pressure reservoir.
EFFECT: technical result is to increase the efficiency of the ICE.
