Cooling System for Cryogenic Fuel Delivery Components
A method for precooling fuel delivery components of a machine having an engine fueled by a cryogenically-stored fuel is described. The fuel delivery components may be configured to operate at an operating temperature at or below a boiling point of the cryogenically-stored fuel. The method may comprise, in a vapor precooling mode, cooling the fuel delivery components to a temperature approaching the operating temperature with a vapor of the fuel taken from a reservoir cryogenically storing the fuel. The method may further comprise, in a liquid precooling mode, further cooling the fuel delivery components to the operating temperature with a liquid of the fuel taken from the reservoir.
