ABSTRACT:
An air cleaner apparatus for an internal combustion engine having a filter element with a generally planar face disposed in a direction parallel to the flow of air, the apparatus includes a central portion and an air guide disposed adjacent the central portion. The central portion communicates with the air guide through the filter element. The central portion has at least one air inlet in operative communication with the engine for permitting the flow of air from the air guide through the filter element and into the engine. The air guide includes an air scoop and an air exhaust, each disposed in a plane generally perpendicular to the direction of the flow of air relative to the housing. The air scoop and the air exhaust are disposed at opposite ends of the filter element such that a portion of the flow of air entering the air guide through the air scoop enters the central portion through the face of the filter element. The remainder of the flow of air exits the air guide through the air exhaust. A fan operatively coupled to the air guide is configured to increase the velocity of the portion of the flow of air moving in the air guide between the air scoop and the air exhaust.
