Abstract

PURPOSE:To restrain effectively and pertinently the occurrence of an injurious ingredient in exhaust gas, by sending back a part of burned exhaust gas to the inlet side of an engine and regulating the quantity of recirculated exhaust gas according to the quantity of fuel injected. CONSTITUTION:A valve mechanism 5 regulating the quantity of the reflux of a part of the exhaust gas of a Diesel engine 1 flowing back from an exhaust passage 3 to an inlet passage 2 through a reflux passage 4 is operated by a negative pressure actuator 7 through a link mechanism 6. On this actuator 7 is impressed through a pipe 40, a negative pressure generated in a negative pressure source 8 and regulated by a pressure regulating device 9. On the other hand, valve units 17, 20 operated respectively by electromagnetic coils 21, 22 controlling the introduction of the atmosphere and the negative pressure are arranged in the pressure regulating device 9, and each electromagnetic coil 21, 22 controls the opening of the valve mechanism 5 by a control unit 24 as the opening becomes optimum value determined according to the quantity of fuel injected to the engine.
