This Stirling Engine Generator Model is a functional external combustion engine designed for physics experiments, science education, mechanical demonstrations, and hobby collection. Made from stainless steel and aluminum alloy, the model demonstrates the operating principles of a classic Stirling engine through heat-driven mechanical motion.

The Stirling engine was invented in 1816 by Robert Stirling and operates through repeated cycles of gas expansion when heated and contraction when cooled. As an external combustion engine, it continuously burns fuel outside the cylinder while the internal gas drives piston movement through thermal expansion and cooling cycles.

Compact and mechanically engaging, this model is suitable for educational demonstrations, desktop display, science projects, and hands-on learning for engine enthusiasts and students.

⚙️ Working Principle

The Stirling engine generates power through repeated heating and cooling cycles. Gas inside the engine expands when heated and contracts when cooled, driving the piston and flywheel to create continuous reciprocating mechanical motion.

🛠 Instructions for Use

1. Place the engine model on a flat and stable surface.
2. Install the heating tube onto the heating cylinder head. During installation, slowly rotate and carefully insert the tube to avoid damaging the sealing ring and heating tube. Keep the heating tube parallel after installation to prevent friction between the displacement piston and heating tube.
3. Remove the alcohol lamp cap and fill the lamp to approximately 2/3 capacity using pure alcohol only. Do not use other fuels. Ignite the alcohol lamp safely.
4. Heat the engine for approximately 20 seconds, then the flywheel can begin rotating.
5. Do not touch high-temperature areas during operation.

⚠️ Safety Notes

• Do not touch heated metal parts during or after operation to avoid burns.
• Avoid touching the alcohol lamp during prolonged heating.
• Suitable for ages 16 and above.
• During heating, ensure the alcohol lamp wick does not touch the boiler.
• Do not apply oil to the piston.
• The model does not require lubrication oil.
• The engine operates at high speed; prevent vibration or falling during operation.
