    摘要: In a voltage boost circuit for driving a fuel injector of an internal combustion engine, a high voltage developed in the voltage boost coil will be discharged into the battery power supply through the boost coil by electrically energizing a discharge switching element provided in parallel to the charging diode. If the overboost compensation overlaps a boost execution period, the end of the boost execution period will await starting of the overboost compensation.

    摘要: In a drive unit of a fuel injection device, an electric current is supplied to the fuel injection device by applying a high voltage to the fuel injection device from a high voltage source whose voltage is boosted to a voltage higher than a battery voltage at the time of opening a valve of the fuel injection device. Thereafter, the electric current supplied to the fuel injection device is lowered to a current value at which a valve element cannot be held in a valve open state by stopping the applying of the high voltage from the high voltage source. Thereafter, in a stage where a supply current is switched to a hold current, another high voltage is applied to the fuel injection device from the high voltage source.

    摘要: A control apparatus for a direct injection type engine is provided for reducing an amount of fuel that adheres to and that remains on a crown surface of a piston so as to suppress the increase of Number of particles as well as advancing the first injection as much as possible when plural fuel injections are carried out in one cycle in the direct injection type engine. The first injection timing is set based on a pulse width of at least the first injection among each of injections split plural times, and when the pulse width of the split first injection is short, the injection timing of the first injection is more advanced as compared with a case of a longer pulse width of the split first injection.

    摘要: The drive device is configured to, during a time interval between an earlier fuel injection (first fuel injection) and a later fuel injection (second fuel injection), supply an electromagnetic coil with an intermediate current at a voltage with a level of not opening the valve. Further, the drive device sets a voltage application for supplying the intermediate current to initiate before a valve closing in the earlier fuel injection and terminate before half a period of time between a first instant when the valve is closed in the earlier fuel injection and a second instant when a supply of a drive current for opening the valve is initiated in the later fuel injection.
