Abstract (en)
[origin: US4840155A] A fuel injection pump, capable of providing a preliminary fuel injection and a main fuel injection, includes a pump piston movable in a housing to define a pump working chamber which is connected with a fuel injection valve during the pumping stroke of the piston. The working chamber is relieved by the valve-closing member of the pressure valve. A magnetic valve which controls the function of the pressure-closing member is provided in the pump. An opening pressure of the pressure valve is greater than that of the fuel injection valve so that the preliminary injection is obtained with the initially open magnetic valve whereas the duration of the main fuel injection is controlled by the closed magnetic valve.
