Abstract

PURPOSE:To carry out the superior recirculation of exhaust gas by setting the value which is obtained by subtracting a prescribed correction quantity from a fuel injection quantity instruction value, as fuel injection quantity, when the cumulative value of the correction value on the basis of the difference between the actual revolution speed and an aimed revolution speed is larger than a prescribed value. CONSTITUTION:The fuel injection quantity instruction value is obtained on the basis of the cumulative value of the prescribed correction quantity by an idle revolution speed controller M2 when a Diesel engine M1 is idling. A fuel injection controller M3 controls fuel injection on the basis of the fuel injection instruction value. In this case, a means M4 judges if the cumulative value of the correction quantity is larger than a prescribed value or not, and when said value is larger, a means M5 calculates the value which is obtained by subtracting the correction in a prescribed quantity from the fuel injection quantity instruction value, as the fuel injection quantity. While, a means M6 sets an exhaust gas recirculation rate, and a means M7 adjusts a control valve M1b in an exhaust gas recirculation passage M1a for the suction side on the basis of the exhaust gas recirculation rate which is set in the above.
