Sunnytech Stirling Engine Education Toy LT001-M14-06-S

The LT001 Stirling Engine Model is a remarkable piece of engineering that boasts an array of impressive features. Crafted with a silver plate and a gold flywheel, this engine can reach speeds of up to 180-200 RPM, with a starting temperature difference of approximately 20°C (68°F). The engine's construction utilizes a variety of premium materials, including carbon steel, nickel-plated carbon steel, stainless steel, glass, bronze, PVC foam, and various plastics. Measuring 101014cm (3.94 3.94 5.51 in) and weighing 250g (0.55Ib), this Stirling engine comes complete with a detailed user manual, ensuring a seamless user experience.

Complementing the LT001, the M14-06-S Stirling Engine model delivers exceptional performance with its speed range of 1300 to 1700 RPM and a weight of 460g (1.02Ib). Boasting impressive dimensions of 200 x 100 x 90 mm (8.0 in 3.93 in 3.74in), this engine showcases technical parameters including a flywheel diameter of 54mm, a driving wheel of 24mm, a power cylinder inner diameter of 14mm, a piston path of 16.0mm, and a cylinder inner diameter of 19.0mm.

These Stirling engines are a testament to exceptional craftsmanship and engineering. Meticulously constructed with high-quality materials, the engines feature mirror-surface stainless steel bases, glass cylinder liners, and zinc alloy flywheels. All components have undergone surface treatment to prevent rusting, ensuring a long-lasting and oil-free operation.

The ease of use of these Stirling engines is truly remarkable. Simply pour a cup of hot coffee, place the engine on the cup, and witness its mesmerizing performance. As the coffee cools, the engine's speed will slow down, indicating the perfect temperature for enjoyment. For even more captivating displays, users can place the engine on a cup of hot water with small ice cubes on the upper plate, creating a greater temperature difference for an even more dynamic and exciting performance.

The exceptional craftsmanship of these Stirling engines is evident in every detail. The boards are made of high-quality Russian pine, expertly manufactured through fine grinding techniques. The power cylinders and pistons are crafted from fine-milled SUJ2 alloy steel, while the displacer piston's rod employs fine-milled bearing steel. Furthermore, the engines feature large quartz glass tubes as hot cylinders, reducing the risk of bursting during operation.

The ease of operation and long-lasting performance of these Stirling engines are equally impressive. Users simply need to fill the alcohol burner with 95% alcohol (the recommended fuel) and ignite it. After letting the cylinder burn for approximately 20 seconds, a gentle push on the flywheel is all it takes to set the engine in motion, allowing it to run continuously for over 8 hours without any issues.

These Stirling engines are not just functional marvels but also captivating conversation pieces. Watching the engines come to life on a cup of hot water or coffee is a delightful and mesmerizing experience, often sparking curiosity and excitement among guests. It's a true joy to witness the engine's hypnotic performance and share the fascination with others, creating unforgettable moments of wonder and discovery.
