<P>PROBLEM TO BE SOLVED: To provide an accumulator fuel injection control device for preventing the fluctuation of actual pressure in an accumulator to keep it as approximate target pressure, while avoiding the shortage of a discharge amount due to a fuel supply pump. <P>SOLUTION: The accumulator fuel injection control device comprises a target pressure setting means for setting target pressure P<SB>0</SB>of fuel in the accumulator 1, and a viscosity detecting means for detecting the viscosity of the fuel. When in the conditions that the discharge amount of the fuel from the fuel supply pump 3 to the accumulator is kept constant and the supply amount of the fuel from the accumulator to a fuel injection valve 2 is kept constant, the current target pressure set by the target pressure setting means is corrected to be lower depending on the detected viscosity of the fuel so as to keep the actual pressure of the fuel in the accumulator almost stable as constant target pressure. <P>COPYRIGHT: (C)2007,JPO&INPIT |
