Abstract:

A fuel delivery system for delivering fuel from a fuel tank to an internal combustion engine includes a fuel pump disposed within the tank and an accumulator communicating between the fuel pump and the engine for storing a volume of fuel under pressure. The system also includes a fuel pump control means for controlling the output of fuel flow from the fuel pump. The control means selectively causes the fuel pump output flow to either supply fuel to both the engine and the accumulator or bypass fuel at a lower pressure while fuel is supplied by the accumulator alone, thereby reducing the average power demand of the pump.
