PURPOSE:To simultaneously further easily perform altitude compensation and supercharged pressure correction of a supercharger, by providing a negative pressure control valve, which generates negative pressure in accordance with an intake air quantity, and negative pressure controller operating an injection quantity regulating member in accordance with said negative pressure. CONSTITUTION:A driving shaft 2 of a fuel injection pump 1 is driven by a Diesel engine 3. An injection quantity regulating lever 41 is operated by a negative presure responsive controller 55, and a level of negative pressure is controlled by a solenoid opening and closing valve 61 and arithmetic device 63. The arithmetic device 63 receives output signals of an intake air quantity 64, temperature detector 65 and speed detector 67. In this way, altitude compensation and correction of supercharged pressure of a supercharger can be simultaneously further easily performed. |
