Abstract
A fuel injection controller for an internal combustion engine includes first and second calculation sections. The first calculation section acquires a fuel pressure at a predetermined point of time before an injection starting point of time and calculates an injection time using the acquired fuel pressure. The second calculation section acquires a fuel pressure when the injection starting point of time arrives and calculates the injection time by using the acquired fuel pressure. The controller is configured to, before starting the energization to the injector, set a point of time to stop energization to an injector based on a calculation result of the injection time by the first calculation section. The controller is also configured to, after starting the energization to the injector, reset the point of time to stop the energization to the injector based on a calculation result of the injection time by the second calculation section.
