御燃料噴射装置。 Each cylinder is equipped with a fuel injection valve, and each fuel injection valve is configured to inject fuel in synchronization with the intake stroke of the corresponding cylinder, and also controls swirl by opening and closing a portion of the cross section of the intake passage. In an electronically controlled fuel injection device for an internal combustion engine having a swirl control mechanism, an injection end timing for increased swirl is set during swirl increase control by the swirl control mechanism, and the injection end timing for increased swirl is set in an operating state other than the setting operation state. Injection end time setting means for setting an injection end time for reducing swirl that is a predetermined earlier than the end time for injection for increasing swirl; engine operating state detecting means for detecting the operating state of the engine; and engine operating state detecting means for detecting the operating state of the engine. injection time calculation means for calculating the fuel injection time based on the engine operating state detected by the means; and injection time calculation means for terminating the injection at the injection end time set by the injection end time setting means. an injection start time setting means for setting an injection start time based on the calculated fuel injection time; and an injection start time setting means that starts outputting a drive pulse signal to the fuel injection valve at the set injection start time to inject the fuel for the injection time. An electronically controlled fuel injection device for an internal combustion engine, comprising injection control means.
