Abstract
PURPOSE: To prevent frequent occurrence of unpleasant shocks due to the shutdown of fuel by making the shutdown of fuel only when the integrated value since the beginning of fuel supply is larger than a given value during the deceleration period when a throttle valve is at idling position.
CONSTITUTION: The arithmetic unit 7 receives output signals from each of the throttle switch 4, the intake air temperature sensor 5, and the revolution sensor 6, and then calculates a basic injection amount TP=KQ/N (K is constant) based on both the intake air amount Q from the intake air temperature sensor 5 and the revolution number N from the revolution sensor 6. And, a correction is made for TP according to the operational parameter of the engine temperature, etc., to calculate the actual fuel injection amount Ti, and the fuel injection valve 8 is opened for a period corresponding to Ti every one revolution of the engine. Furthermore, the value of TP is integrated and when the switch is ON and during the deceleration period when the revolution number is less than a given value NC, fuel supply is shutdown when the integrated value of TP is more than the standard value SL to save the consumption of fuel.
