DIY Single Cylinder Stirling Engine Product overview A single cylinder Stirling engine that converts heat into mechanical motion through gas expansion and compression by the cold side. Constructed from selected metal with a silver appearance, precise machining, and a stable, firm base for reliable operation and display. Key benefits Demonstrates a clear physical principle: visualizes heat to mechanical energy conversion using the Stirling cycle. Handson learning tool: improves practical assembly skills and deepens understanding of thermodynamics and mechanical motion. Durable and precise: precision coordination of parts and sturdy metal construction provide consistent performance and lasting use. Simple visual feedback: a diode lights when the engine is running, providing an immediate indication of successful operation. Features and specifications Type: DIY single cylinder Stirling engine. Material: selected metal with silver finish and fine workmanship. Base: stable and firm for tabletop use and demonstrations. Performance: operates by gas expansion and compression by the cold side; precise part fit supports smooth rotation of the flywheel. Indicator: diode glows when the engine is running. How to use Fill the alcohol lamp to about two thirds full with alcohol. Ignite the alcohol lamp and place it under the heating cylinder. Preheat the heating cylinder for about 30 seconds. Turn the flywheel by hand to help the engine start. When running, the diode will glow to show successful operation. Practical applications Classroom demonstrations and lab experiments to illustrate thermodynamic principles and energy conversion. STEM projects and hobbyist builds to practice assembly, calibration, and observation of small mechanical systems. Science fairs and exhibits as an eye catching, handson display that invites interaction and explanation. Notes Use an appropriate alcohol fuel and handle open flame with care. Operate on a stable, heat resistant surface and follow standard precautions for working with small heat sources.
