Abstract:
1. An engine assembly comprising: an air generating component that includes a radiator fan; an air cleaner positioned to filter out debris carried by ambient incoming air prior to entry into an engine; a scavenging conduit attached to the air cleaner and including a first end positioned to receive the debris from the air cleaner, and an exhaust end opening to an environment outside the engine for discharging the debris to the environment; a duct extending between the air generating component and the scavenging conduit, and a second end of the duct opening into the scavenging conduit in a direction and at a location between the first end and the exhaust end to blow air from the air generating component toward the exhaust end of the scavenging conduit; and wherein the blow air generates suction pressure at the first end of the scavenging conduit to pull the debris out of the air cleaner and push the debris out of the exhaust end into the environment.
