PURPOSE:To prevent a spark plug from smoldering as well as to keep off an output drop and a worsening of emission control, by making reduction speed of accelerating increment quick in time of low temperature but slow in time of high temperature, respectively. CONSTITUTION:When an accelerating state of an engine (a) is detected by a detecting device (b), a fuel injection quantity is increased by an increasing device (d) according to engine temperature (c) at that time, and in this case, it is increased much in time of low temperature but less in time of high temperature. At the time of reducing an accelerating increment value by a reduction device (e), this reduction speed is controlled according to the engine temperature (c). That is to say, in time of low temperature, it is reduced quickly but in time of high temperature slowly. With this constitution, smoldering in a spark plug due to excess fuel injection is preventable from occurring and, what is more, a tendency of making an air-fuel ratio, in time of acceleration, into being lean is also preventable. |
