Abstract:
An internal combustion engine comprising:a fuel combustion chamber having an exhaust port at which heated fuel exhaust generated by combustion is released from said chamber;a heat regenerator comprising a heat conductive element configured to promote turbulent flow of said fuel exhaust therethrough in communication with said exhaust port for extraction of heat from the fuel exhaust;a fluid source for releasing a fluid into the heat regenerator, whereby the fluid absorbs said heat and forms a heated vapor;a heat transfer valve for controlling the release of said vapor into said chamber for powering the engine; andwherein the volume of the fuel combustion chamber is controllable such that a first volume of the chamber at the initiation of combustion is different than a second volume of the chamber at the initiation of the release of said vapor.
