Abstract

A low fuel shut-off system for a Diesel engine which includes a fuel supply circuit comprising a main fuel tank, a transfer pump, a filter array, an injection pump, injection nozzles, and an auxiliary fuel tank in the fuel circuit between the transfer pump and the injection pump. A level sensor in the auxiliary fuel tank provides a signal when the fuel level drops below a predetermined point, with the signal being used by associated electrical control to shut down the engine while a supply of fuel still remains in the fuel supply circuit between the auxiliary tank and the injection pump, and in the auxiliary tank, which is sufficient to start the engine without priming.
