ABSTRACT:
To inhibit an air pulsating sound resulting from the opening and closing of the air control valve in a cold engine and to improve controllability of ISC functions in an assist air supply apparatus. When an engine is cold based on a cooling water temperature sensor, opening control is performed so as to control the amount of supplied assist air by controlling the opening degree of an air control valve. When the engine is warming-up, injection synchronization control is performed, in which opening and closing of the air control valve are controlled in synchronization with fuel injection from the fuel injection valves. Therefore, it is possible to suppress air pulsating noise resulting from the opening and closing the air control valve when the engine is warming up and to improve controllability of ISC functions in an assist air supply apparatus.
