Abstract:
A fuel injection apparatus comprising:a fuel injection pump connected with a plurality of fuel injection nozzles by way of a plurality of fuel passages;first decision means for determining a desired fuel injection amount;second decision means for determining a final injection control amount in consideration of a property of the fuel, the second decision means comprising:detecting means for detecting the fuel pressure in each fuel passage;computing means for computing a parameter representing the property of the fuel in accordance with the detected fuel pressure;correction means for correcting an injection control amount in accordance with the computed parameter to obtain the final injection control amount, wherein the injection control amount is determined by the operating status of an engine to accomplish the desired fuel injection amount; andcontrol means for controlling the injection pump in accordance with the final injection control amount so that the injection pump is pumping out the desired fuel injection amount under high pressure at a required timing; wherein the parameter represents the bulk modulus of the fuel.
