Abstract
A diesel fuel supply circuit comprises a diesel engine (100); a fuel cooler (104); a fuel tank (102), and a valve (114). The valve (114) is operable to move the fuel cooler (104) from (1) a position within the circuit in which it cools fuel leaving the diesel engine (100) and going to the fuel tank (102) to (2) a position in which it cools fuel leaving the fuel tank (102) and going to the diesel engine (100) and vice versa.
Claims16
A diesel fuel supply circuit comprising:
- an engine (100) having an engine fuel inlet and an engine fuel outlet;
- a fuel cooler (104) having a cooler fuel inlet and a cooler fuel outlet;
- a fuel tank (102) having a fuel tank inlet and a fuel tank outlet;
- and
- a valve (114) coupled to the engine (100), the fuel cooler (104) and the fuel tank (102), the valve (114) having at least two configurations, the at least two configurations comprising a first configuration in which the valve (114) couples the fuel cooler (104) between the engine (100) and the fuel tank (102) to receive fuel from the engine fuel outlet and provide the fuel to the fuel tank inlet, and a second configuration in which the valve (114) couples the fuel cooler (104) between the fuel tank (102) and the engine (100) to receive fuel from the fuel tank outlet and provide fuel to the engine fuel inlet.
