Abstract: A fuel system for a diesel engine is provided that includes a fuel supply tank module for storing fuel. The fuel supply tank module includes a fuel pump module reservoir which has an in-tank low pressure lift pump and a bimetallic thermostatic flow valve. The fuel system also includes a fuel filter module for filtering fuel pumped from the fuel supply tank module, a high pressure pump for pumping fuel from the fuel filter module, a diesel engine for receiving fuel from the high pressure pump, and a fuel return line for returning fuel to the bimetallic thermostatic flow valve. The bimetallic thermostatic flow valve includes a bimetallic element in thermal communication with the returning fuel. The bimetallic element deflects in response to the thermal communication so that returning fuel flows to at least one of the fuel pump module reservoir and the in-tank low pressure lift pump.

Abstract: A thermostatic valve for a diesel fuel system includes a valve housing and a valve element movable within the housing between a position directing heated diesel fuel returning from an engine to the inlet of a fuel pump and a position dumping the fuel into a reservoir where the fuel mixes with lower temperature fuel. A temperature responsive thermostatic element moves the valve element in response to the temperature of the diesel fuel. A temperature relief valve is provided in the housing to dump the returning fuel into the reservoir if the temperature reaches a temperature indicating overheating of the fuel. The temperature relief valve is a bi-metal valve mounted in an end wall of the valve housing.

Abstract: The present invention refers to a fuel pressure regulator assembly and method for regulating the pressure of the fuel supplied to the fuel rail at a predetermined pressure. The fuel pressure regulator includes a housing and fuel cover for containing the fuel pressure regulator and submersing the fuel pressure regulator in fuel at all times. A valve element allows excess fuel to exit the fuel pressure regulator and return to the fuel tank for reuse. The fuel component assembly also allows for a method of reducing turbulent fuel flow and for controlling noise and hydrocarbon emissions. The method is achieved by providing a containment assembly that submerges the pressure regulator in fuel for containing and directing fuel flow path.
