ABSTRACT:
The heart of a heat engine is a reciprocating expansion chamber, which converts heat from a hot fluid into mechanical work. The expansion chamber utilizes a refrigerant in a liquid state as an input, and heats and expands the refrigerant to move pistons and generate work. A high pressure injector injects the liquid refrigerant into the chamber under enough pressure to keep it in a liquid state until it is desirable to have it expand into a gas. A hot fluid is the heat source for the expansion chamber and cold fluid is an output. Another output is the refrigerant, now a hot, low pressure gas. A compressor pressurizes the refrigerant, forming a hot, high pressure gas, and a condenser generates liquid refrigerant and provides it to the pressure injector.
