<P>PROBLEM TO BE SOLVED: To improve the compliance of actual fuel pressure for a target fuel pressure at the time of fuel cut recovery in controlling the discharging amount of a high-pressure fuel pump 6 so as to obtain the target fuel pressure set up in accordance with an operating condition by detecting the fuel pressure inside the fuel accumulator 10, in a fuel control system provided with a fuel accumulator (high-pressure piping) 10 for storing high-pressure fuel from the high-pressure fuel pump 6 and a fuel injection valve 12 in which the high-pressure fuel in the fuel accumulator 10 is led. <P>SOLUTION: Part (10b) of the fuel accumulator 10 is blocked, and a solenoid valve 16 capable of reducing the volume of the fuel accumulator 10 (10a) is provided. At the time of the fuel cut recovery, the volume of the fuel accumulator room 10 (10a) is reduced by temporarily closing the electric valve 16. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
