PURPOSE:To prevent a drop in the output torque due to delay of the response of an air intake sensor when auxiliary machines are inputted into action, by attenuating a fuel injection signal after adding a quantity increase signal to a fuel injection signal, as well as by opening a throttle valve correspondent to the action of the auxiliary machines. CONSTITUTION:An air flow meter 6, an O2 sensor 9 and an engine speed sensor 12 are connected to a control device 14 to control the valve opening time of a fuel injection valve 2. An air control valve 8 installed on an auxiliary passage 7, that bypasses the throttle, makes an opening movement by linking with an auxiliary machine switch 16 for an air conditioner, etc., when the switch is 'ON'. In response to the opening movement, a quantity increase device 15 adds a quantity increase signal to the fuel injection valve 2 and then attenuates this quantity increase signal.
