<p>To secure an appropriate fuel injection even when an environmental temperature is in a low temperature region, with a simple configuration, thus enabling a realization of a high stability and reliability fuel injection. With a common rail fuel injection control apparatus configured capable of a multi injection, a temperature correction factor which suppresses a deterioration in a fuel injection amount correction when an environmental temperature is in a low temperature region is used when calculating a correction amount in the fuel injection amount correction executed in order to reduce a fuel injection amount pulsation occurring between a preceding fuel injection and a fuel injection succeeding a finishing of the preceding fuel injection in one engine cycle, and an appropriate fuel injection is secured by obtaining an appropriate correction amount even when the environmental temperature is in the low temperature region, thus enabling a realization of a high stability and reliability fuel injection.</p> |
