    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.

    摘要： There is provided a high-pressure fuel pump drive circuit for manipulating the electric current to be passed to a solenoid coil for controlling a high-pressure pump. This circuit is characterized in that a first switching element, the solenoid coil and a second switching element are connected in series with each other in a rout from a source voltage side to the ground side, that a flywheel diode for passing electric current to a power source is disposed parallel with the solenoid and with the first switching element, and that a Zener diode connected with the power source is disposed parallel with the second switching element, wherein a counter electromotive force to be developed at the opposite ends of solenoid coil on the occasion when the second switching element is changed from ON to OFF is consumed by the flywheel diode provided that the first switching element is in a state of ON, and the counter electromotive force is more rapidly consumed by the Zener diode provided that the first switching element is turned OFF.
