PURPOSE:To improve the acceleration performance in all the range including the intermediate load range corresponding to the intermediate speed by determining the increased-amount correction coefficient according to the engine load when the fuel injection amount is increased for acceleration. CONSTITUTION:A control unit 12 which controls the valve-opening time of a fuel injection valve 4 on the basis of an air flow sensor 2, engine temperature sensor 10, revolution-number sensor 11, etc. calculates the fuel injection pulse width Ti on stationary traveling from the intake air amount Q and the number of revolution (n) in the first step. When acceleration is judged from the variation of the intake air amount Q in the next step, the interruption pulse width Tai and the constant-rate correction coefficient Kac are determined on the basis of the pulse width Ti, engine condition, and engine temperature, and the load correction coefficient Kti is determined on the basis of the fundamental injection pulse width Tp. Then, the load correction pulse width TiXKacXKti is calculated, and output into the fuel injection valve 4. |
