Abstract

PURPOSE: To avoid instability of an engine by stopping or reducing the exhaust gas reflux when gentle acceleration is detected.
CONSTITUTION: In gentle acceleration operation, the output of a comparator 13 is at high level but the output of a comparator 14 is low level because it does not reach an upper limit. As a result, a change-over valve 5 is so operated that a control valve is fed with air or with VC negative-pressure diluted with air, and exhaust gas reflux is cut off or reduced.
