Stirling Engine Model with Propeller Display 8 Cylinder Working Model

16-Cylinder Stirling Engine | External Combustion Heat Engine Model | Stainless Steel + Solid Wood | Functional Generator Toy | Educational Mechanical Display

Product Overview:
This impressive 16-cylinder Stirling engine model is a fully functional demonstration of external combustion principles. Built from high-quality stainless steel and mounted on a solid wood base, it combines mechanical elegance with educational value. With eight heating tubes and eight cooling pipes, this model runs smoothly using only a small alcohol lamp, converting heat energy into mechanical work in a visually captivating cycle.

Key Features:

Elegant Design & Durable Materials:
Crafted from stainless steel and finished with a solid wood base, this engine model offers a sleek, silver aesthetic and sturdy construction.

Functional Heat Engine:
Demonstrates the complete Stirling cycle—cyclic compression and expansion of air as a working fluid under different temperature levels—transforming external heat into rotational mechanical energy.

Multi-Cylinder Power:
Features 16 cylinders (8 heating, 8 cooling), linked via a floating bead mechanism that drives a flywheel for high-efficiency operation. The balanced layout creates powerful motion and consistent rotation when heated.

Quiet, Efficient, and Safe:
Unlike internal combustion engines, this model operates without explosions, making it a quiet, low-emission educational tool perfect for high-altitude environments where external combustion engines excel.

Optional Generator Output:
The engine can power a small generator, allowing you to connect LED lights or similar low-power devices. Simply connect the wires to the generator terminals (LED polarity may need to be flipped if not lighting up).

Operating Instructions:

Place the engine on a level surface.

Manually spin the flywheel to ensure smooth motion; resistance indicates the cylinder is sealed (a normal phenomenon).

Prepare the alcohol lamp using cotton wick and high-purity alcohol (95% or higher; not included). Fill up to two-thirds capacity.

Light the alcohol lamp and position it under the heating tubes.

After about 2 minutes of heating, gently spin the flywheel—the engine should start operating automatically.

Do not touch the heated parts during or after operation until fully cooled.
