Dual function fuel supply module |
摘要 |
A dual function fuel delivery system is provided including a mechanical gear-driven pump and an electric pump. The electric pump is selectively energized to deliver fuel to the mechanical gear-driven pump. The electric pump is energized when an RPM level in the engine is less than a first threshold value or when a fuel rail pressure in a fuel rail of the system is less than a second threshold value. The electric pump is de-energized when the RPM level is greater than or equal to the first threshold value and the fuel rail pressure is greater than or equal to the second threshold value.
