ABSTRACT:
A fuel delivery system for a diesel engine for controlling the propagation of unwanted pressure waves including a fuel pump for sequentially delivering fuel from a fuel tank to a plurality of fuel injectors through a plurality of injection lines. The system further includes a drain line, one associated with each fuel injector, that is connected a pressure source, wherein the impedance of each drain line is equal to the impedance of its corresponding injection line. Each drain line further includes a flow restriction having an impedance equal to the impedance of its corresponding drain line and a valve, connected across the flow restriction for diverting flow around the flow restriction during intervals of time when fuel is flowing from the pressure source towards a particular one of the fuel injectors.
