Fuel injection control apparatus and fuel injection control method for internal combustion engine
Abstract:
A fuel injection valve coupled to a common rail is provided. When fuel injection is carried out, the fuel pressure in the fuel injection valve pulsates. An interval between a pilot injection and a main injection is set so that the main injection is carried out at a zero gradient timing as a timing when the gradient of the fuel pressure in the fuel injection valve after the pilot injection is approximately equal to zero. Owing to a fuel injection control apparatus and a fuel injection control method for an internal combustion engine that perform the above-mentioned control, the fuel injection amount for the subsequent fuel injection following the preceding fuel injection can be reliably held equal to a normal amount.
