Air precleaner arrangement for an internal combustion engine comprising two cyclone filters
Abstract:
An air precleaner arrangement for an internal combustion engine comprises a screen, 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 to provide an air stream from an upstream surface through the openings of the screen to a downstream surface. The shroud encloses the fan and the screen. The first cyclone filter has an air inlet receiving air on the downstream surface of the screen, an air outlet and a scavenge port in communication with interior of the screen and thus with the air stream of the fan. The second cyclone filter has an air inlet connected to the air outlet of the first cyclone filter, an air outlet connected to the air inlet of the internal combustion engine and a scavenge port connected to an exhaust venturi in the exhaust stream of the engine.
