Abstract
PURPOSE:To improve the acceleration performance by varying the standard quantity of the fuel feed quantity for the switching to the open-loop-control from the air-fuel ratio feedback according to the engine load and speedily increasing the acceleration increasing quantity due to the open-loop-control. CONSTITUTION:In a control circuit 20, during the engine operation, the fuel injection time is calculated on the basis of each output signal of an O2 sensor 1, throttle opening degree sensor 10, absolute pressure sensor 11, crank angle sensor 12, and a water temperature sensor 13, and an injector 5 is drive- controlled according to the result of the calculation. In this case, if the calculated fuel feed quantity is less than a standard quantity, the injector 5 is feedback-controlled on the basis of the output of the O2 sensor, while if the fuel feed quantity is larger than a standard quantity, the injector 5 is open-loop controlled independently of the output of the O2 sensor. In this case, the above described standard quantity is controlled according to the engine load.
