Sunnytech Hot Air Stirling Engine Generator Educational Toy

This engine is a balance-style design, which sets it apart from the typical Stirling model. It is equipped with a multicolor LED installation on the motor. Due to the heat from high-grade alcohol, the engine will run rapidly, generating electricity. The power will then be transmitted through the wire, driving the multicolor LED lighting. This creates a truly interesting and imaginative toy.

Regarding the construction, the heating cylinder is made from custom-thick glass material, allowing for long-term heating without pressure. The engine is primarily composed of metal, enabling it to operate quietly and stably at speeds around 1700 RPM due to its substantial weight of 1.5 LB. Our customers have expressed satisfaction with the fit and finish of this engine, and all the parts have undergone surface treatment to prevent rusting. Users will be pleased once they place the engine on a table.

In terms of operation, simply fill the alcohol burner with 95% alcohol (the recommended fuel) and light it. Allow the flame to heat the round-ended cylinder for approximately 60-120 seconds, then gently push the wheel, and the engine will run effortlessly.

The dual-cylinder engine design is full of power, with a voltage output range of 4-9V. The flywheels will rotate rapidly, causing the generator's LED lights to flicker wildly. When the machine is in operation, the sight is truly captivating and will undoubtedly draw attention.

The engine's construction reflects exceptional craftsmanship. The base, bracket, and two flywheels are made of 6061 aluminum alloy, known for its high strength, weldability, and corrosion resistance. The power cylinder and piston are composed of SUJ2 material with a fine-ground surface and special treatment, ensuring high hardness and long-lasting, high-speed operation without significant wear. The axle joints are connected using high-precision miniature bearings, providing stability without the need for lubrication. The power and heat cylinders are manufactured from brass and 304 stainless steel, ensuring an extended service life.

In summary, this engine model, designated as SC02M, has a status of "Assembled" and operates at a speed of 1700-2000 RPM (revolutions per minute). The overall size of the engine is 165x95x120mm/6.50x3.74x4.72in (L/W/H), with a flywheel size of 60x9mm/2.36x0.28in (Diameter/Thickness) and a net weight of 810g/1.79lb. The packing list includes the engine, a lamp, an LED, and a spare tube.
