ABSTRACT:
A smog control device for use particularly on automobiles and comprising an enclosure connectable to the automotive exhaust system and having a passageway therein defined principally by baffles, and a pair of different sized vaned rotors coaxially mounted on a single shaft are disposed in the passageway such that the first smaller rotor is upstream from the second, larger rotor, whereby the first rotor is driven by the automotive exhaust flow and the second rotor is driven by the first rotor to create a partial vacuum in the passageway between the rotors, the partial vacuum being instrumental in causing the precipitation and caking of exhaust pollutants on downstream baffles which are removable for cleaning. A small motor could also be used to drive the rotors.
