Abstract

Official abstract text for this publication.

A fuel injection control apparatus includes a first injection timing setting device, a target second injection timing setting device, a reference injection timing calculator, and a second injection timing setting device. The reference injection timing calculator is configured to calculate, as a reference injection timing, a timing at which a second-injection boosting operation is to be completed. The second-injection boosting operation is to re-boost a reduced voltage which has been reduced because of an execution of a first injection operation by using a booster circuit. The second injection timing setting device is configured to set, as a second injection timing at which a second injection operation is to be started, a later one of a target second injection timing set by the target second injection timing setting device and the reference injection timing calculated by the reference injection timing calculator.

First claim

Opening claim text (preview).

What is claimed is: 1. A fuel injection control apparatus for an internal combustion engine in which a voltage boosted in a booster circuit is supplied to a fuel injection valve so that fuel is injected from the fuel injection valve separately a plurality of times by a first injection operation and a second injection operation, the fuel injection control apparatus comprising: a first injection timing setting device configured to set, as a first injection timing, a crank angle at w…
