摘要： A plunger of a fuel pump is disclosed. The plunger may have a cylindrical base configured for axial movement and rotation within a pump barrel. The plunger may also have a fuel amount controlling end. The fuel amount controlling end may have a recessed surface region. The fuel amount controlling end may also have a sealing surface region. Further, the fuel amount controlling end may have a control interface connecting the recessed surface region with the sealing surface section in a radial direction. The transition from the recessed surface region to the control interface may be curved.

摘要： An injection nozzle is disclosed. The injection nozzle may have a sealing face providing a sealed connection to the nozzle holder. The injection nozzle may also have a needle guiding bore. The needle guiding bore may have a nozzle holder section extending through the sealing face. The needle guiding bore may further have an injection side section fluidly connected to an outside of the injection nozzle via a plurality of nozzle spray holes. The needle guiding bore may also have a high pressure fuel chamber disposed between the nozzle holder section and the injection side section. The injection nozzle may also have a high pressure supply bore extending through the sealing face and fluidly and connect an opening in the sealing face with the high pressure fuel chamber via an extension.

摘要： A fuel supply system for an internal combustion engine may include a plurality of fuel injection pumps, each fuel injection pump being configured to pressurize fuel and provide the pressurized fuel to an associated fuel injector. The fuel supply system may further include a low-pressure fuel supply line fluidly connected to the plurality of fuel injection pumps and configured to provide fuel from a fuel supply tank to the plurality of fuel injection pumps. The fuel supply system may still further include a low-pressure fuel return line fluidly connected to the plurality of fuel injection pumps and configured to return remaining fuel from the plurality of fuel injection pumps to the fuel supply tank. The fuel supply system may include a first fuel cut-off valve disposed in the low-pressure fuel supply line and configured to stop a flow of fuel from the fuel supply tank to the plurality of fuel injection pumps.
