INTERNAL-COMBUSTION-ENGINE FUEL INJECTION CONTROL DEVICE |
摘要 |
An internal-combustion-engine fuel injection control device which can accurately control a boosted voltage applied to a fuel injection valve during fuel injection and can control a variation in a fuel injection amount without increasing a size or a cost of the fuel injection control device even when a width of a fuel injection driving pulse to drive the fuel injection valve is small is provided. A fuel injection control device 127 includes a boosting operation control unit 15 configured to start a boosting operation at predetermined timing regardless of an amount of a detected voltage when the detected voltage is higher than a threshold voltage for starting boosting and is lower than a threshold voltage for stopping boosting. |
