TWO CYLINDER ENGINE The dual-cylinder engine is full of power, and the flywheels will rotate rapidly when the machine is running. This will be a very shocking and eye-catching sight.

HEAVY & STABLE This engine is much larger than most Stirling engines you'll find. Weighing 4 lb, it's very heavy and can run stably on a table.

EXTREMELY FINE CRAFTED The base, bracket, and two flywheels are made of high-strength, weldable, and corrosion-resistant 6061 aluminum alloy. The power cylinder and piston are made of SUJ2 material with a fine grinding surface and high hardness, ensuring they won't wear out even during high-speed, long-running operation. The axle joints are connected with high-precision miniature bearings, providing stability without the need for lubrication. The power and heat cylinders are made of brass and 304 stainless steel, ensuring a long service life.

EASY OPERATION & LONG LASTING Fill the alcohol burner with 95% alcohol (the recommended fuel) and light it. Let the flame burn the round-ended cylinder for about 20 seconds, then give the wheel a gentle push, and the engine will run like a charm. It can run continuously for over 8 hours without any issues, as tested by one of our customers.
