PURPOSE:To prevent variation of fuel injection by correcting the fuel injection completing timing on the basis of voltage applied onto a solenoid valve while controlling the fuel injection completing timing on the basis of a rotary timing signal. CONSTITUTION:In step 100, fuel injection Q is calculated from the engine rotation NE and accelerator opening ACCP. In step 105, correction level TB for the battery voltage VB is calculated. While in step 114, the time TQO required for engine to rotate by 1 deg. CA and the correction level TB are added to produce the time TQ. In step 117, the off-time of solenoid valve is obtained and set in conveyor register A. Consequently, variation of fuel injection caused through variation of engine rotation and battery voltage can be prevented. |
