Abstract
A diesel fuel feed system comprises a diesel engine (100); a fuel cooler (102); a fuel tank (106); and a makeup valve (104).
Claims18
A diesel fuel feed system comprising:
- a diesel engine (100) having a fuel inlet and a fuel outlet, the fuel inlet of the diesel engine (100) being configured to receive diesel fuel for combustion in the diesel engine (100), and the fuel outlet of the diesel engine (100) being configured to convey fuel in excess of fuel combusted in the engine (100) away from the engine (100) for reuse;
- a fuel cooler (102) having a fuel inlet and a fuel outlet, the fuel inlet of the fuel cooler (102) being coupled to the fuel outlet of the diesel engine (100) to receive the excess fuel from the engine (100), to cool the excess fuel, and to convey the cooled fuel to the fuel outlet of the fuel cooler (102);
- a fuel tank (106) having a fuel inlet and a fuel outlet, the fuel outlet of the tank (106) being configured to supply fuel from the tank (106) to the diesel engine (100);
- and
- a makeup valve (104) having a first fuel inlet, a second fuel inlet and a fuel outlet, wherein the first fuel inlet of the makeup valve (104) is coupled to the fuel outlet of the fuel cooler (102) to receive substantially all of fuel therefrom, wherein the second fuel inlet of the makeup valve (104) is coupled to the fuel outlet of the fuel tank (106) to receive substantially all fuel therefrom, and wherein the fuel outlet of the makeup valve (104) is coupled to the fuel inlet of the engine (100) to provide the engine (100) with substantially all fuel thereto.
