内燃機関の割込噴射制御装置。 An engine operating condition detecting means including an engine rotating speed detecting means for detecting the engine rotating speed, a fuel injection amount setting means for setting the fuel injection amount based on the detected engine operating condition, and interposed in the engine intake passage. Throttle valve opening detection means detects the opening of the throttle valve; acceleration determination means determines the acceleration operation state based on the rate of change in the throttle valve opening; and In an interrupt injection control device for an electronically controlled fuel injection internal combustion engine, the interrupt injection control device includes an interrupt injection amount setting means for setting an injection amount, and a fuel injection means for injecting and supplying the set fuel injection amount to the engine. an interrupt injection cancel means for canceling the interrupt injection when the throttle valve opening exceeds a predetermined value; and a predetermined value of the throttle valve opening for canceling the interrupt injection, which is detected by the engine rotation speed detecting means. 1. An interrupt injection control device for an electronically controlled fuel injection type internal combustion engine, characterized in that the interrupt injection control device is configured to include a cancel opening setting means for setting the cancel opening according to the engine rotation speed.
