PURPOSE:To improve response performance and stability by carrying-out asynchronous injection by a prescribed number of times when the variation of throttle opening degree reaches a prescribed value or more and afterwards carrying-out asynchronous injection only in the case when the throttle opening degree varies by at least the max. amount of variation up to that time. CONSTITUTION:Acceleration is judged on the basis of one detection value among the throttle opening degree, intake pressure, and the amount of intake air. The variation of the detection value over LVI set in Step 42 is judged in Step 44. If acceleration is judged, asynchronous injection is carried-out in Step 46. Afterwards, increment is performed in a counter C in Step 47. In Step 48, the max. amount MXD of variation of the detection amount up to the previous time and the amount of variation of the detection amount at this time are compared, and if the amount of variation at this time is larger, asynchronous injection is carried- out. Thus, response performance and stability can be improved. |
