ABSTRACT:
In the control unit of internal combustion engine, in which the exhaust gas recirculation (EGR) quantity to an intake pipe is adjusted by the EGR valve, an EGR regulator controls an opening degree of the EGR valve according to the fuel injection value. And the EGR regulator decreases the opening degree of the EGR valve quickly to the minimum when the increase of the fuel injection valve in a unit time exceeds a criterial value. Further, an EGR buffer prevents the EGR regulator from quick-decreasing the opening degree of the EGR valve when the fuel injection value is wiggling by the operation of the cruise controller.
