Abstract

PURPOSE:To prevent the instantaneous over-learning of air-fuel ratio and to prevent drop of idling rotating speed by asynchronously injecting fuel when an air conditioner is operated during idling. CONSTITUTION:Detection values of an intake pipe pressure sensor 48, an intake air temperature sensor 50, a water temperature sensor 54, O2 sensor 56, an air conditioner switch 64, a throttle switch 66 and so on and an ignition from an ignition coil 68 are input to a control portion 60. The control portion 60 computes asynchronous injection pulse width when an engine is in the idling operating condition, the rotational frequency is less than idle-up rotational frequency (1,000rpm) and the air conditioner switch 64 is turned on. When synchronous injection is not conducted, asynchronous injection is performed with the operation of the second negative pressure switching valve 78 to idle up.
