Abstract

PURPOSE:To enable a control device to correspond to a difference of fuel distribution between cylinders and to a cylinder quantity variably controlled engine or the like by providing a number of time counting counters corresponding to a number of cylinders and separately performing their time control in every cylinder. CONSTITUTION:A control IC4 provides in its inside counters CNT1-CNTn in quantity (n) corresponding to the cylinder quantity of an engine while comparators CMP1-CMPn similarly in quantity (n) respectively comparing a value of each counter with the value of a comparator register 5. While the control IC respectively inputs an engine crank angle signal POS and a cylinder discriminating signal REF, outputting a trigger signal T being based on these input signals. By an AND value obtained by the trigger signal and the cylinder discriminating signal, the control IC starts counting by any one of the counters while, during this time, sets an output from any one of the comparators to a value of 1, outputting an injection pulse to a number of injection valves #1-#n.
