摘要： PROBLEM TO BE SOLVED: To improve the operability of an engine and suppress emission of noxious exhaust gas components by suppressing fuel injected from a fuel injection valve J from getting excessively dense in returning to the normal engine operation state by being released from the rapid deceleration engine operation. SOLUTION: The fuel discharged from a fuel pump P is controlled to a first prescribed pressure A (kgf/cm2) by a first pressure control valve R and fed to a demand type fuel pressure control valve DR via a first fuel channel F1. The fuel is then controlled to a second prescribed pressure B (kgf/cm2) reduced compared with the first prescribed pressure A (kgf/cm2) in the demand type fuel pressure control valve DR and fed to the fuel injection valve J via a second fuel channel F2. When the pressure in the second fuel channel F2 including a fuel distribution pipe D exceeds the second prescribed pressure B (kgf/cm2) and raised to the pressure not more than the first prescribed pressure A (kgf/cm2), the pressure in the second fuel channel F2 is released via a check valve V.

摘要： PROBLEM TO BE SOLVED: To improve the operability of an engine, and to restrict the discharge of the harmful exhaust gas component by restricting the over concentration of the fuel to be injected from a fuel injection valve J when canceling the quick decelerating operation of the engine for reset to the normal engine operation. SOLUTION: A second negative pressure passage 2 continued to a spring chamber 14 of a first fuel pressure control valve R is divided from one end of a first negative pressure passage 1 for communicating an intake tube K1 with the inside of a fuel tank K through a branch part S. A selector valve V for selectively communicating a first negative pressure passage IC closer to the end than the branch part S or the second negative pressure passage 2 is arranged in the branch part S. When cutting the fuel with the fuel injection valve J (quick decelerating operation time), the selector valve V communicates the first negative pressure passage 1 with the second negative pressure passage 2 so as to lower the pressure of the fuel flowing in a first fuel passage F1 in comparison with the first predetermined pressure A kgf/cm2.
