とする内燃機関の燃料噴射量制御装置。The basic injection amount of fuel is set based on the intake pressure and engine rotation speed detected at regular intervals, and the acceleration of the engine is determined based on the amount of change in the intake pressure per unit time.
In a fuel injection amount control device for an internal combustion engine that performs increase correction control on the fuel injection amount when acceleration is detected, each time the intake pressure is detected, the difference between the latest detected value and the detected value several times before is determined. Fuel injection amount for an internal combustion engine, characterized in that an acceleration detection means is provided for determining acceleration by comparing a value obtained by dividing the obtained amount of change in intake pressure by the plurality of detection intervals as a unit time with a reference value. Control device.
