Abstract:
A fuel module for pumping and filtration of a fuel in a fuel system includes a flow housing, and each of an electrically powered pump, a first cartridge filter, and a second cartridge filter in sealed, direct engagement with the flow housing. The fuel module is applied in a low pressure fuel circuit feeding fuel to a high pressure fuel circuit for pressurization to an injection pressure. Electronic closed loop control techniques for the pump are also disclosed.
