A controller operates the fluid circuit to collect heat from the power electronics system and to selectively deliver the heat to the intake air heat exchanger.

A system and method to improve the efficiency of an internal combustion engine by delivering an air/fuel mixture to the combustion chamber in a pure gaseous state. The system accepts an air/fuel mixture from a carburetor or injector which is placed into a vaporized state before entering the combustion chamber of the engine. An intake track capable of withstanding exhaust gas temperatures of an internal combustion engine is constructed and arranged to cause vaporization of fuel and inhibit the vaporization from condensing.
