速時割込み増量制御装置。 An intake air flow rate detection means for detecting the intake air flow rate of the engine, a fuel injection amount setting means for setting the fuel injection amount based on the detected intake air flow rate, and a drive pulse signal corresponding to the set fuel injection amount. In an electronically controlled fuel injection internal combustion engine, the electronically controlled fuel injection internal combustion engine includes: drive pulse signal output means for intermittently outputting a drive pulse signal to a fuel injection valve; an interrupt increase setting means for setting an interrupt increase fuel amount based on the acceleration state detected by the acceleration state detection means; and an interrupt drive pulse signal corresponding to the set interrupt increase fuel amount to inject the fuel at the same time as acceleration detection. An interrupt drive pulse signal output means for outputting to the valve, an engine load detection means for detecting the engine load, and an interrupt for determining whether or not the engine operating region is a prohibition region for interrupt increase based on the detected engine load. An electronically controlled fuel comprising: an increase prohibition determination means; and an interrupt prohibition means for prohibiting the interrupt drive pulse signal output means from outputting an interrupt drive pulse signal when the interrupt increase prohibition determination means determines a prohibited area. Interrupt amount increase control device during acceleration of injection type internal combustion engine.
