K311 Golden Mini Low Temperature
K311 Golden Mini Stirling Engine Model – Educational Low‑Temperature Physics Toy
- High‑quality alloy construction: Durable one‑piece aluminum alloy base reduces air leakage and ensures smooth, precise operation.
- Fully pre‑assembled: Ready to run straight out of the box—no tools or complex setup required.
- Works on a low‑temperature differential: Powered by modest heat—just hot water—demonstrating cryogenic engine principles.
- Compact & lightweight: Measures roughly 9.5 × 9.5 × 11 cm; weighs about 250 g.
- Precision craftsmanship: Fine polished golden finish for aesthetic appeal and educational impact.
✅ Why You Should Buy It:
- Engaging STEM learning: Watch heat energy transform into kinetic energy in real time—ideal for classrooms, science fairs, or curious minds.
- Stylish desktop decor: A golden engine that doubles as a conversation-starting ornament.
- Low maintenance design: Lubricate with pencil powder (not oil) to keep friction minimal and longevity high.
- Great for all ages: Recommended for ages 6 and up (adult supervision advised).
🧪 How It Works:
- Pour hot water (≥ 65 °C) into a cup that fits under the engine base.
- Place the engine over the cup so its base heats up.
- After ~30 – 60 seconds, gently spin the flywheel clockwise to start motion.
- As the aluminum base warms, the temperature differential drives the piston, generating rotation without any electric power.
Is the engine safe to operate ?
Yes—just avoid direct contact with hot surfaces. Engine components may heat up; use pencil powder for lubrication, not oil.
What materials is it made from ?
Aluminum alloy and stainless steel with a golden polish; transparent protective base supports.
How do I maintain or clean it ?
Use pencil powder to lubricate moving parts. Do not immerse in water or use strong magnets near the piston—those materials can affect performance.
What age group is this suitable for ?
Recommended for 6 years and older. Younger users should use under supervision.
🔧 Lifestyle Use Ideas:
- Classroom or educational labs: Perfect to illustrate basic thermodynamic principles in physics lessons.
- Desk or shelf display: Adds vintage-mechanical charm to offices, studies, or engineering-themed decor.
- Gift for STEM enthusiasts: Ideal for hobbyists, educators, or anyone intrigued by physics and innovation.
Features:
– Stirling Engine: Mainly made of metal, the dreamy and eco-friendly machine model is exquisite, aesthetic and rich in metallic luster.
– Simple Operation & Easy Use: Put it on a water cup or coffee cup with a water temperature above 90 degrees Celsius, then turn the flywheel into a magical operation after half a minute of preheating for an enjoyable toy on your desk.
– Build to Last and Continuous Running: The enduring and sturdy engine works silently. It will run continuously and permanently, as long as the temperature difference is enough, which is capable of placing on your desk and office table for a long time.
– Wide Application: The affordable and stunning model can be used for scientific laboratory projects, energy conversion&dynamics studies and teaching demonstrations. It is also available as an astounding toy and talking point between you and your friends, and everyone will wonder how it works.
– Ideal Gift: The Stirling engine is a perfect birthday or Christmas gift to surprise friends, family, parents, and children, a delicate toy for model collectors and an incredible teaching tool for school teachers.
Cautious: You only need to fill the glass by about half. If there’s a bit of mechanical noise, just lubricate it with a little graphite to quiet it down. You can scrape the graphite off a pencil with a knife. Do not lubricate it with oil for the oil will mix with dust in the air to form greasy dirt, which will give the Stirling engine too greater friction to run freely.
Note: Due to shooting angle and lighting, the engine model in the picture has color difference, please refer to the actual product.
