Abstract:
An apparatus for cooling fuel and fuel delivery components in an internal combustion engine, comprising:at least one fuel-cooling block, having at least one fuel entry port for receiving fuel from a fuel tank and having at least one fuel exit port coupled to said fuel delivery components for supplying cooled fuel thereto; a system for circulating cooling fluid, comprising: at least one cooling fluid block having at least one cooling fluid entry port coupled to a cooling fluid pump, and having at least one cooling fluid exit port coupled to a cooling fluid radiator in which heat is exchanged, said cooling fluid block, said cooling fluid pump and said cooling fluid radiator being coupled to allow cooling fluid to circulate through said system; and A thermoelectric unit, having electrical terminals for receiving power from a power supply, having a cold side thermally coupled with said fuel-cooling block for heat exchange, and having a hot side thermally coupled with said cooling fluid block for heat exchange; such that the fuel is cooled by exchanging heat from said fuel to said cold side of said thermoelectric unit, and such that said cooled fuel also cools the fuel delivery components.
