Abstract
An air cleaner for use in combination with a fuel system of an engine, includes an air cleaning element housed within a casing. Air introduced from an air inlet, defined in the casing, follows an air flow path from the air inlet passing through the air cleaning element. The air flow path includes a direction change of approximately ninety degrees. This direction change transpires over a curved guide surface formed in the casing to reduce the likelihood of vortexes which reduce the air ram pressure. The curved guide surface may include a detachable panel. Also, the panel may include an air path to an air branch chamber. When two air inlets are used, it is advantageous to include a partitioning wall separating the two air flow paths prior to the air cleaning element.
