Patent ID: 6945235

Claim:
A method for increasing the amount of EGR flow and enhancing exhaust gas recirculation efficiency on a combustion engine, comprising: providing a combustion engine having an exhaust system including a manifold configured to receive exhaust gases from a plurality of engine cylinders and to convey at least a portion of the exhaust gases downstream to an exhaust outlet; providing at least one juncture off of the manifold that conveys at least a portion of the exhaust gases to an exhaust gas recirculation system; locating a reflector at the manifold in association with the exhaust outlet, the reflector adapted to reflect at least a portion of exhaust gas pressure pulses emitting from the combustion engine thereby causing a reflected pressure pulse to occur in the manifold and configuring the reflector as a gasket secured between a first and a second flange; and deflecting at least a portion of the reflected pressure pulse into the exhaust gas recirculation system thereby enhancing the efficiency of the exhaust gas recirculation system.
