Self-assembly — complete kit
All parts supplied + detailed instruction manual (in English). Develops manual skills and understanding of mechanisms.
Solid metal body
Robust and durable, resistant to high temperatures without deformation — a quality of execution suitable for both educational use and decoration.
Integrated alcohol tank
Simplifies starting — fill the tank, light it, and the engine starts. No external equipment required.
Large flywheel + precision connecting rods
Smooth and continuous movement once started — the rotation of the flywheel perfectly illustrates the conversion of thermal energy into mechanical energy.
16 × 5.8 cm — 456 g
Compact size, can be placed anywhere — desk, shelf, display case. Lightweight and easily movable for demonstrations in class or meetings.
Exceptional mechanical gift

Stirling QX6 — solid metal, alcohol tank, 16 × 5.8 cm, 456 g, complete kit
The Stirling engine is one of the most elegant inventions in the history of thermodynamics: no internal combustion, no explosion — just the temperature difference between a hot end and a cold end that sets the piston in motion. The QX6 makes this principle visible and tangible: solid metal body resistant to high temperatures, integrated alcohol tank for immediate start-up, large flywheel for smooth and continuous movement. Once assembled, it runs silently as you watch thermodynamics at work.

Operating principle: The Stirling engine utilizes the temperature difference between a hot end (heated by the alcohol tank) and a cold end (at ambient temperature). This difference creates a cyclical expansion and contraction of the trapped air, which sets the piston in motion. No combustion, no explosion — just pure thermodynamics.

Frequently Asked Questions
How does a Stirling engine work?
A Stirling engine exploits the temperature difference between a hot zone (heated by alcohol) and a cold zone (ambient air). This difference causes the cyclical expansion and contraction of the air in the cylinder, setting the piston in motion and continuously rotating the flywheel. No internal combustion — just pure thermodynamics.
Is the kit difficult to assemble?
No — the kit is designed to be assembled by intermediate-level DIY enthusiasts. All parts are supplied along with a detailed instruction manual (in English). Allow 1 to 2 hours for assembly depending on your modeling experience.
What fuel should I use to operate it?
Isopropyl alcohol or methylated spirits (methanol or ethanol) — to be poured into the integrated tank. A few milliliters are enough for several minutes of operation. The integrated tank makes starting immediate and requires no external equipment.
Is it suitable for classroom use?
Yes — this is one of its main advantages. Its compact size (16 × 5.8 cm) and silent operation make it an ideal demonstration tool to concretely illustrate thermodynamic principles. Suitable for high school students, science students, and engineering training programs.
