PURPOSE:To improve operation characteristic of an engine with simple, high accuracy sequential control by controlling both start and finish timings independently by means of two series of timer functions. CONSTITUTION:Measuring elapsed time, every time a basic signal is inputted from a crank angle sensor C, by means of an injection start timing detection means E, the injection start timing calculated with an injection start finish timing operation means D is detected. Also, outputting an injection start signal from an injection start signal output means G to an injection pulse outputting means B for a cylinder discriminated with a cylinder discriminating means F, injection is started. Then, measuring an elapsed time from the injection start time with an injection finish timing detection means H, the injection finish timing calculated with the injection start finish timing operation means D is detected. Also at the same time, outputting an injection finish signal from an injection finish signal detection means I to the injection pulse outputting means B for a cylinder discriminated with the cylinder discriminating means F, injection is finished.
