摘要： In an engine such as an engine for driving a pump or dynamo, in which a load increasing state does not appear as an accelerating state of rotation speed, it is intended to prevent the smoke emission in an abruptly load-increasing state, which might otherwise be caused by the suppression or interruption of an EGR quantity. The engine 10 comprises a supercharger 11 and an exhaust gas recirculation (EGR) device 12. The engine 10 makes an isochronous control or a droop control, when its rotation speed N is shifted from a no-load (idle) or light-load run to a high-load (load-increasing) state. In case it is detected, when the state of the engine 10 shifts to a load state, that the actual rotation speed N becomes lower by a predetermined rotation speed ΔN than a target rotation speed Nm, an EGR valve 13 of the exhaust gas recirculation (EGR) device 12 is either throttled to an opening smaller by a predetermined opening ΔF than the ordinary set opening F corresponding to the load state or fully closed.

摘要： In an electronic control governor that adjusts the amount of fuel supplied to an engine so as to coincide an engine rotation speed with a target rotation speed, by driving an actuator for actuating a fuel adjusting mean due to an actuator driving current overlapped with a dither current, an amplitude or frequency of the dither current is changed, corresponding to a change in the supply quantity of the actuator driving current. Or, the amplitude and frequency of the dither current are changed corresponding to a change in the engine rotation speed. Alternatively, a ratio between turn-on time and turn-off time during one period of the dither current is changed, depending on the velocity ratio between the increased velocity and the decreased velocity of the actuator driving current. Preferably, the ratio of the turn-on time to one period of the dither current is set at 20 to 40%.

Of these actuators (88, 89), one (88) is stopped and the operation for providing a pressurized supply of fuel is performed from only the other actuator (89), so that the timing at which the load torque that acts on the crankshaft of the engine becomes a local maximum and the timing at which the load torque that acts on the driveshaft of the high-pressure pump (8) becomes a local minimum are made to coincide with one another.
