FIELD: engines and pumps.
SUBSTANCE: proposed aspiration system is intended for ICE including air intake and combustion products discharge at increased temperatures. Engine comprises air pre-cleaner communicated with engine air intake and arranged upstream thereof. Said air pre-cleaner prevents an ingress of coarse contaminants in engine air intake and their accumulation. Said air pre-cleaner has outlet for contaminants. Aspiration system comprises the element that makes a primary engine exhaust gas primary flow channel. Said element has section of Venturi pipe and pipe with outlet nearby Venturi pipe section. The latter is communicated with pre-cleaner contaminants outlet to allows their injection in and through said pipe. Said element has at least one ambient air inlet into primary flow channel for exhaust gas cooling nearby said element.
EFFECT: better removal of contaminants.
