Abstract

PURPOSE:In an exhaust recirculation system of an internal combustion engine, the mixing of recirculation exhaust and mixed gas is accelerated and the formation of NOx in exhaust gas is decreased by introducing recirculation exhaust to the place at which the flow velocity of mixed gas is maximum, namely between the suction valve and the valve seat in each cylinder.
