ABSTRACT:
An electromagnetic fuel injection valve for injecting fuel by opening/closing a fuel flow path, includes a valve seat, a valve element for opening/closing the fuel flow path formed between the valve seat and the valve element, and a drive unit having at least one coil for driving the valve element. The drive unit includes a first magnetomotive force generating device using the at least one coil and a second magnetomotive force generating device, the first magnetomotive force generating device and the second magnetomotive force generating device being composed so that the first magnetomotive force generating device generates and raises its magnetomotive force at a larger rate of change in time in comparison with the second magnetomotive force generating device. A valve open state is held by the second magnetomotive force generating device which uses a smaller current flow in comparison with the first magnetomotive force generating device.
