Abstract
A fuel injection controller is applied to a fuel injector injecting fuel to be combusted in an internal combustion engine by an open-valve operation of the valve body according to an electromagnetic suction force generated by an energization of a coil. The fuel injection controller controls an injection state of the fuel injector by controlling a coil current flowing through the coil. The fuel injection controller includes an increasing control portion which increases the coil current to a first target value, a holding control portion which holds the coil current increased by the increasing control portion to the first target value, and a changing portion which changes the first target value according to the operation state of the internal combustion engine.
