車両用デイーゼルエンジンの燃料噴射ポンプ。 In a fuel injection pump for a diesel engine for a vehicle, the fuel introduced from the low pressure chamber into the plunger pressurizing chamber is distributed and pressure-fed to each cylinder by a plunger that rotates and reciprocates in synchronization with engine rotation, and the plunger pressurizing chamber and the low pressure chamber A solenoid valve is provided to close this return passage at a predetermined injection start time, and a spill passage is formed in the plunger to communicate the plunger pressurizing chamber and the low pressure chamber. A control sleeve is provided to open the spill passage at a predetermined injection end timing in conjunction with an accelerator pedal, and means for detecting the operating state of an air conditioner for cooling the passenger compartment;
The vehicle is characterized in that it is provided with a fuel increase device that displaces the control sleeve in a direction to retard the injection end timing or advances the closing timing of the solenoid valve when the accelerator pedal is closed according to the detected value. Diesel engine fuel injection pump.
