H8103 Stirling Engine Kit 3

The Stirling Engine was invented and developed by Reverend Dr. Robert Stirling and his brother, James, in the early 1800's.

In the conversion of heat into mechanical work, Stirling engines can achieve the highest efficiency of any real heat engine, limited only by the proper- ties of the working gas, engine materials, and fric- tion. These engines can run on any heat source of sufficient quality, including solar, chemical, and nuclear.

Compared to an internal combustion engine of a given power rating, Stirling engines have a higher initial cost and are usually larger and heavier. However, in recent years, the advantages of Stirling engines have become increasingly signifi- cant due to the rising concerns over energy and environmental issues.

The Stirling engine is a closed system and con- tains a fixed quantity of gas that, in this kit, is air. Unlike other types of piston engines that require outside ventilation, the Stirling engine is sealed, no gas enters or leaves the engine, and no valves are required. The Stirling engine cycles through four main processes—cooling, compression, heating and expansion. This is accomplished by moving the enclosed air back and forth between hot and cold heat exchangers.

The round, horizontal heating exchanger in con- tact with the alcohol burner warms the working air and the smaller cylinder on top cools it. A change in the enclosed air temperature will cause a cor- responding change in gas pressure, while the motion of the piston causes the enclosed air to be alternately expanded and compressed.

In summary, the Stirling engine uses the energy difference between its hot and cold ends to create a cycle of alternately expanding and contracting a fixed amount of enclosed gas, and converting the temperature differences into mechanical power.
