Abstract

PURPOSE: To obviate the detrimental influence upon an engine by detecting the idle condition through the control lever of a fuel pump to operate a throttle valve which is mounted in an exhaust passage.
CONSTITUTION: A throttle valve 10 is provided downstream of the open end 9a of the EGR passage 9 of an exhaust passage 8, and the idle condition of an engine is detected in terms of the operating position of the control lever 3 or the like of a fuel injection pump 2. In response to the detected signals, the throttle valve 10 is operated so that it is throttled only during the idling. The throttle valve 10 is used to reduce the throttled quantity of the exhaust gases during the operations other than the idling condition, and at the same time the effective open area of the EGR passage 9 is controlled. Thanks to such constrution, proper EGR can be obtained, and the detrimental influence upon the engine performance can be obviated.
