摘要： 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.

摘要： A fuel injection control apparatus includes a first injection controller, a second injection controller, and a selector. The first injection controller is configured to perform a first injection operation in an intake stroke and is configured to perform a second injection operation in a compression stroke. The second injection controller is configured to perform both the first injection operation and the second injection operation in the intake stroke. The selector is configured to select fuel injection performed by the first injection controller when an internal combustion engine is in a warm-up operating state and is configured to select fuel injection performed by the second injection controller when the internal combustion engine is not in the warm-up operating state.
