FIELD: engines and pumps.
SUBSTANCE: invention relates to engine building and can be used in gas distribution mechanism of internal combustion engine. Essence of the invention is in the fact that in exhaust gas tract exhaustion is created using energy of exhaust gases. Gas streams are separated at outlet in such a way that one stream passes through exhaust valve of increased diameter, and the second stream goes through exhaust valve for ventilation of combustion chamber. Next, the flows pass through the discharge manifold and the ventilation manifold to the ejection unit, where exhaust gases is ejector gas, and the ejected gas is the air from atmosphere entering through the intake and vent valves.
EFFECT: technical result is to increase in engine power and to reduce in fuel consumption while reducing harmful substances in exhaust gases.
