Abstract

1408980 Reducing pollution from internal combustion engines F BECKER and H H JONES 19 Dec 1973 58817/73 Heading C1A [Also in Divisions B1 and A1] Air pollution from the exhaust of an internal combustion engine having an exhaust port for the products of combustion and an air intake, is reduced by: (a) separating the lighter fraction of the products of combustion from the heavier fraction thereof; (b) passing said lighter fraction of the products of combustion to said intake; (c) passing said heavier fraction of the products of combustion through perforated conduits located within and adjacent to the bottom of a closed chamber having a treating mixture therein comprising triethanolamine, fuller's earth, and ethylene glycol, with the level of said treating mixture being above said perforated conduits; (d) cooling said treating mixture; and (e) removing gases from an upper portion of said recepticle. A small amount of water soluble oil may be added to the treating mixture to prevent corrosion.
