PURPOSE:To reduce the dispersion of the ingition timing between cylinders by installing an ignition detector for each cylinder and controlling the injection timing so that each ignition timing of all cylinders accords with an aimed ignition timing in idling. CONSTITUTION:An ignition detector 1b equipped with a phototransistor for detecting the light which is generated on combustion is installed onto each cylinder. The time when an accelerator zeroposition sensor 1g is turned ON and the engine revolution number is less than 1,000rpm and a transmission position neutral sensor 1h is turned ON is judged as idling timing, and at this time, the injection timing is controlled so that each ignition timing of the all cylinders accords with an aimed ignition timing. Thus, the dispersion of the ignition timing between cylinders is reduced. |
