ンプ。A pressurizing chamber is formed on the end face of the plunger, and while the plunger is moving in the direction of increasing the volume of the pressurizing chamber, fuel is introduced into the pressurizing chamber from the fuel filler port, and the plunger is moving in the direction of decreasing the volume of the pressurizing chamber. During movement, fuel is pumped from the pressurized chamber to the engine side,
In a diesel engine fuel injection pump that forms a control group that communicates the pressurizing chamber with the oil supply side at the end of the plunger's pumping stroke, a preliminary injection control group that communicates with the oil suction side is provided between the plunger end face and the control group. Fuel injection pump for diesel engines.
