Plane Head Pocket piston Stirling Engine Motor External Combustion Model Toy Overview A compact, tabletop external combustion Stirling engine model that demonstrates closedcycle heattomotion principles. Designed for clear observation and reliable operation, it combines metal, quartz glass, and plastic components in a pocketsized display model. Key benefits Clear demonstration of thermodynamic principles: The piston Stirling design shows gas compression and expansion caused by temperature differences, making the engine ideal for teaching and handson learning. Easy to operate and observe: Heat the included alcohol lamp, spin the propeller to start, and watch the engine run steadily and quickly. The transparent heating tube lets you follow the process in real time. Durable, attractive construction: Main body in aluminum alloy with a sandblasted finish resists wear and maintains appearance. Thick quartz glass heating tube provides longlasting heat resistance and reliable performance. Features and performance Operation type: External combustion, closedcycle piston Stirling engine. Startup: Simple heat source driven start using the supplied alcohol lamp. No electrical power required. Visible mechanism: Quartz glass heating tube and exposed propeller head allow observation of motion and heat exchange. Materials: Metal (aluminum alloy main body), quartz glass heating tube, plastic components. Size and weight: Product dimensions 13 x 12.5 x 9.8 cm. Product weight 270 g. Compact for desktop use and transport. Package: Box packing. Package dimensions 21 x 11.5 x 15 cm. Package weight 450 g. Package contents 1 Stirling engine model 1 alcohol lamp 1 manual Recommended uses Classroom demonstration: Use in physics or engineering lessons to illustrate heat engine cycles, thermodynamics, and energy conversion. Laboratory or workshop demonstration: A practical aid for smallscale experiments and demonstrations that require a visible, repeatable heatdriven mechanism. Desk display and conversation piece: Place on an office desk or display shelf to spark curiosity and explain basic engineering principles to visitors. How to run 1. Place the engine on a stable, level surface. 2. Fill and light the included alcohol lamp beneath the quartz heating tube following the manual instructions. 3. Gently spin the propeller head to initiate motion; the engine will run as the working gas heats and cools. 4. Allow the lamp to cool and extinguish before handling or packing. Notes Designed for educational and display use. Follow the included manual for safe setup and operation.
