Abstract
A cooling system for the fuel used in a diesel engine includes a closed fuel injection circuit and a fuel cooling circuit. The fuel injection circuit receives fuel through a suction pipe from a fuel tank and provides a continuously circulating flow of fuel. The fuel cooling circuit flows fuel from and back into the fuel tank. A heat exchanger is connected to both of the circuits and flows the fuel from the fuel injection circuit in indirect heat transfer relation with the fuel in the cooling circuit for removing heat from the fuel in the injection circuit.
Claims8
A cooling system for the fuel used in a diesel engine comprises a fuel tank, a suction pipe connected at one end to said fuel tank, a closed fuel injection circuit connected to the other end of said suction pipe for receiving fuel from said fuel tank, a fuel cooling circuit having an inlet end and an outlet end each opening into said fuel tank, a fuel pump for circulating fuel through said fuel cooling circuit, a heat exchanger connected to said fuel cooling circuit and to said closed fuel injection circuit for circulating the fuel flowing in said closed circuit in indirect heat transfer relation with the fuel circulating in said fuel cooling circuit.
