Abstract: Apparatus for removing particulate from gases. The apparatus includes an inlet conduit, an outlet conduit, and a cylindrical gas processing chamber positioned between and interconnecting the inlet conduit and outlet conduit. The processing chamber is also connected to a particulate collection chamber by a channel. The gas processing chamber includes a cylindrical wall. A hollow cone-shaped deflector member is positioned in and spaced away from the walls of the processing chamber and is positioned between the inlet and outlet conduits. Gases entering the apparatus flow through the inlet conduit and contact the deflector member. The deflector member directs the major portion of gases from the inlet conduit radially outwardly toward the wall of the gas processing chamber. The gases deflected radially outwardly travel around the deflector member and along the wall of the processing chamber.

Abstract: An exhaust gas recirculation system for an internal combustion engine. The internal combustion engine including at least one combustion chamber; an intake mechanism for delivering a combustible fluid mixture to the combustion chamber; an ignition system for igniting the combustible mixture; and an exhaust system for carrying exhaust fluid produced by the combustion of the combustible fluid mixture away from the combustion chamber. The exhaust gas recirculation system includes a mechanism for diverting a portion of the exhaust fluid passing through the exhaust system; a conduit attached to the diverting mechanism for carrying the diverted fluid to the intake mechanism of the internal combustion engine; a heat sink connected to the conduit for removing heat from the diverted portion of the exhaust fluid; and a filter integrated along the conduit to remove particulate from the diverted exhaust fluid.
