Abstract
The process of removing embedded particulates from the pore surfaces of an ngine air cleaner (pleated paper type) is facilitated by blowing pulses (or jets) of compressed air through the filter media in the reverse flow direction. The invention relates to the employment of a fluidic oscillator for producing the air pulses. The oscillator is used in a switching mode such that alternate pulses are applied to different air cleaner sections. Overall objective is to achieve an effective cleaning action with a relatively small quantity of compressed air.
