Abstract:
Methods and systems are provided for cooling a high pressure fuel pump. One method includes, when a spill valve is in a pass-through state, circulating fuel from a compression chamber of the high pressure fuel pump to a step room of the high pressure fuel pump. The fuel circulation through the step room may provide for a reduction in fuel temperature in the step room, and thus, the high pressure fuel pump.
