Abstract
PURPOSE:To improve the acceleration performance by estimating the fresh air intake quantity for each cylinder on the basis of the time from the detection of acceleration to the opening time of suction valve in each cylinder and the variation rate of the opening degree of a throttle valve and setting the intrerruption injection quantity for each cylinder on the basis of these values. CONSTITUTION:A detecting means A for detecting the opening degree variation rate of a throttle valve is installed, and the output signal is inputted into an acceleration judging means B, and when the opening degree variation rate over a prescribed value is detected, it is judged that the engine is in acceleration state. The crank angle in the first time in the acceleration judgement is set by an acceleration detection crank angle setting means D on the basis of the output of a crank angle detecting means C, and the interruption injection quantity for each cylinder is set by an interruption injection quantity setting means E from the relative time between the pertinent crank angle and the suction valve opening time for each cylinder and the above-described variation rate of the opening degree. In the engine acceleration state, an output means F outputs the interruption injection pulse signals corresponding to the interruption injection quantity into each fuel injection valve G within a prescribed crank angle of the corresponding cylinder.
