Abstract
A drive control circuitry and an electronic control circuitry for controlling energization of a plurality of fuel injection valves. The plurality of fuel injection valves including a second fuel injection valve currently injecting fuel and a first fuel injection valve which, of the plurality of fuel injection valves, was last energized before the second fuel injection valve. When an energization start interval between a start of energization of the first fuel injection valve and a start of energization of the second fuel injection valve is longer than or equal to a peak reaching time of the first fuel injection valve, an energization time of the second fuel injection valve is extended as the energization start interval reduces. When the energization start interval is shorter than the peak reaching time, the energization time of the second fuel injection valve is reduced as the energization start interval reduces.
