Title: Exhaust gas recirculation system of engine
Inventor: ISAKA YOSHIHARU
IPC: F02B17/00
Filed: 1993-01-14
Abstract: PURPOSE:To reduce the NOx in realizing the stratified combustion of both mixed and unmixed flows of exhaust gas by forming an exhaust gas supply port in a partial intake passage alone, and connecting this supply port to an exhaust through a course followed, in an exhaust gas recirculation system which recirculates the exhaust gas to a combustion chamber of an engine equipped with plural lines of an intake passage. CONSTITUTION:In a driving area where an intake air quantity is little, an intake control valve 18 is turned to the full-close position by a control unit 27, and a bottom wall side of each branch passage 7b is throttled down. In succession, intake air partially flows to a top wall side, producing a tumble, and combustion is stabilized. At this time, an exhaust gas feed pipe 25 is opened by the control unit 27 via an EGR control valve 26, while the exhaust gas is drawn into the branch passage 7b from the feed pipe 25 and a supply passage 23 with the open of an intake valve 9, making this exhaust gas mix the intake air flowing into the top wall side. With this constitution, a flow velocity of the intake air is heightened, thereby producing the tumble with certainty. In addition, a mixed flow of the exhaust gas is fed to the vicinity of a spark plug, and an initial combustion temperature is lowered to some extent and thereby a harmful ingredient in the exhaust gas is reduced.
