This disclosure relates to an air cleaner for use in an air-cooled engine including a cooling fan within a fan housing. The cleaner is connected to draw air from the housing, and includes a casing having a side wall, an air inlet opening in the fan housing, an air passage formed within the casing and extending from the inlet along the wall, the passage including a curved portion, and a narrow opening formed in the wall adjacent the curved portion. The curved passage causes dust particles to move by reason of inertia to the radially outer side of the passage and the particles are removed through the narrow opening.
