Abstract
An air-fuel supply system for an internal combustion engine in which fuel, such as natural gas, is stored in a fuel tank as a cryogenic liquid, and in which supply air is compressed. The charge air is intercooled to increase its density and, therefore, engine performance. Heat from the intercooling process is utilized to vaporize the liquid natural gas fuel. Heat exchange from the charge air to the liquid natural gas is accomplished with a phase changing heat transfer fluid. The heat transfer fluid boils at the intercooler and condenses at the fuel vaporizer to give precise temperature control at the intercooler surfaces without frost build-up.
