Abstract
A fuel injection control for an internal combustion engine includes a coil, a first switch, a capacitor, a second switch, and a control circuit. The coil is to boost a voltage of a power supply source. The first switch is connected at one end to an output side of the coil and at the other end to a ground. The capacitor is connected to an electromagnetic fuel injection valve to store energy which has been stored in the coil. The second switch is connected at one end between the coil and the first switch and at the other end to an input side of the capacitor. The control circuit is connected to the first switch and the second switch. The control circuit is configured to perform synchronous rectifying control for switching the first switch and the second switch.
