Abstract

PURPOSE: To purify exhaust gas by the constitution that each of main suction passage and a sub suction passage including a main suction valve or a sub suction valve is communicated into a combustion chamber and the sub suction valve smaller in diameter than the main suction valve is opened or closed earlier than the main valve near an ignition plug provided.
CONSTITUTION: One end of an exhaust gas recirculation passage 20 is opened to an exhaust pipe 19 connected to an exhaust passage 16 and the other end of the passage 20 is connected with a sub suction passage 6, that constitutes an exhaust gas recirculation system a. The passage 20 includes an exhaust gas recirculation control valve 21 which is parted into a negative pressure chamber 22 and an atmosphere chamber 23 by a diaphragm 24 held by a spring 26, and is assembled with a valve body 25. The negative pressure chamber 22 is connected with a suction pipe 14. As the sub suction valve is opened earlier, so much more secondary air is supplied for the exhaust passage. Exhaust gas can be exactly reburnt or oxidized and the formation of HC, CO may be reduced.
