ABSTRACT:
A pump system for preventing hot start knock in a diesel engine following engine shut down carried by fuel leakage into one or more of the combustion chambers of a multiple-cylinder internal combustion engine equipped with a fuel system including open nozzle injectors connected with a common rail. The system includes a transfer pump (46) in fluid communication with the common rail (50) and the fuel tank (48) for pumping fuel out of the common rail and into the fuel tank. A transfer pump control module (82) is provided for actuating the transfer pump (46) for a period of time following engine shut down to remove a sufficient amount of fuel from the common rail to prevent fuel from leakage through the open nozzles. The control system module may include a timer (96) and a voltage sensor (86) to sense condition of a fuel shut off valve (64). A retrofit kit (FIG. 5) is provided including a control module bracket (98) and a transfer module bracket (102).
