THERMAL MOTOR AND METHOD FOR CONTROLLING THE THERMAL CONDUCTIVE OF THE WALLS OF THE COMBUSTION CHAMBER

摘要

The general field of the invention is that of thermal engines. The device comprises at least one mechanical element and a control unit, the mechanical element comprising a wall forming part of the combustion chamber, characterized in that the wall of the mechanical element consists of a material whose thermal conductivity is cyclically controlled in phase with the phases of the engine cycles by application of an electric field, the electric field being controlled by the engine control unit.The invention proposes a heat engine whose performance and reliability can be improved by optimization of heat exchange taking place during the operating cycles.
