ABSTRACT:
An internal thermal exchanger engine which, in one embodiment, includes a cylinder having side walls and an enclosed lower end, with a piston mounted for reciprocal movement within the cylinder, and with a heat exchanger reciprocally mounted within the cylinder between the piston and the lower end of the cylinder. A gas phase fluid is enclosed between the piston and the lower end of the cylinder. The heat exchanger, which has perforated end portions, contains a foraminous heat conductive material distributed throughout the entire volume of the heat exchanger, thus allowing the gas phase fluid to pass freely through the heat exchanger as the heat exchanger moves between the piston and the lower end of the cylinder. A solenoid mounted on the piston operates an exchanger rod secured to the heat exchanger so as to cause the heat exchanger to move reciprocally within the cylinder. A combustion chamber is provided at the lower end of the cylinder to provide a source of heat.
