Abstract: The “Internal Combustion Engine Energy Extractor” is a device that is extracts otherwise wasted heat from both the engine exhaust system and it's cooling system. This heat is converted into mechanical energy, which is 1) used to power the “Extractor” and 2) may be used for auxiliary engine devices, such as an intake air supercharger or an electrical generator. The Energy Extractor by itself 1) increases engine efficiency and power by decreasing exhaust back pressure and 2) decreases engine wear by decreasing the cylinder and engine temperature.
