Stirling Engine Model with Alcohol Lamp Key features and benefits Novel propeller design: Uses propeller blades instead of a traditional flywheel for a distinctive look and smooth motion, making it an engaging desktop technology model. Durable materials: Main body made from aluminum alloy with a polished and oxidized surface to resist fading and corrosion. Cylinder and piston are manufactured to precision for consistent performance. Reliable heat component: Quartz heating tube is designed to resist damage from rapid thermal expansion and contraction, providing safer and more stable heating during operation. Ready to run: The model is assembled and tested before . Simple start procedure lets you run the engine quickly for demonstration or display. Educational and entertaining: Demonstrates basic Stirling engine principles through visible, lowspeed motion, useful for teaching, hobby exploration, or handson curiosity. Specifications Material: Aluminum alloy and quartz tube Product size: 15 x 8 x 9 cm Product weight: 370 g Package dimensions: 19 x 13 x 11 cm Package weight: 500 g Packing: Box Package content Stirling Engine Model x1 Alcohol Lamp x1 How it works and how to start Fill the provided alcohol lamp with 95% alcohol and light it. Place the lamp under the hot cylinder and allow the cylinder to preheat for a short period. Help start the unit by manually turning the propeller once; the engine will continue to run as heat is maintained. The engine runs on external heat and converts thermal differences into smooth mechanical motion, suitable for demonstration and display. Practical use scenarios Desktop conversation piece: Place on an office or home desk to demonstrate engineering principles and invite curiosity. Classroom demonstration: Use in science lessons to show heat to motion conversion and basic thermodynamics in a visible, lowrisk format. Hobby and model display: Add to a mechanical model collection or use during workshops to illustrate precision machining and smallscale engine mechanics. Safety and care Do not touch heating parts while the lamp is lit or immediately after use to avoid burns. Do not add oil to the cylinder or piston, as lubrication can reduce the engine s operating efficiency. Use only in a well ventilated area and follow basic fire safety when using the alcohol lamp. The model is intended for educational and display use. Keep out of reach of unsupervised children. This Stirling engine model combines precision aluminum construction and a quartz heating tube with a distinctive propeller design to provide a reliable and engaging smallscale demonstration of thermodynamic motion.
