摘要：An air precleaner arrangement for an internal combustion engine comprises ascreen, a shroud, a fan, a first cyclone filter and a second cyclone filter. The screen has air
permeable openings sized to retain debris. A fan is cooperating with the screen toprovide an air stream from an upstream surface through the openings of the screen to adownstream surface. The shroud encloses the fan and the screen. The first cyclone filterhas an air inlet receiving air on the downstream surface of the screen, an air outlet and ascavenge port in communication with interior of the screen and thus with the air streamof the fan. The second cyclone filter has an air inlet connected to the air outlet of thefirst cyclone filter, an air outlet connected to the air inlet of the internal combustionengine and a scavenge port connected to an exhaust venturi in the exhaust stream of theengine.
