PURPOSE:To make the generation of particulate and black smoke at highland reducible, by compensating for decrement of a fuel injection quantity control command value according atmospheric pressure, in case of accelerating compensation to be done in time of sudden acceleration. CONSTITUTION:A compensation operational device 108 of an arithmetic unit 105 discriminates to be in time of sudden acceleration when an actual variation speed is larger than the preset variation speed, by means of each output out of a device 109 calculating a load compensation range on the basis of an engine speed sensor 101, a device 110 calculating the preset load variation speed and a device 107 calculating the actual load variation speed from a signal out of a load detecting device 103, and if it is the compensation range, a control command value to a fuel injection quantity adjusting mechanism 104 is compensated. Here, according to atmospheric pressure by an atmospheric sensor 102, a compensation operational device 112 makes the preset variation speed smaller, while a compensation operational device 111 compensates it so as to cause the compensation range to be enlarged, decreasing the fuel injection quantity according to a pressure drop. |
