Embark on an exploratory journey into mechanical engineering with the 4 Cylinder V4 Stirling Engine Kit. This fascinating model demonstrates how the Stirling engine converts heat into electricity, lighting up LED lights in varying colors, making it an excellent educational and creative inspiration.

Features:

1. Dynamic Generator: The Stirling engine model boasts a power generation voltage of 4-9V, matched with colorful LED lights. The rapidly rotating flywheel causes the LEDs to flicker, creating a visually stunning effect.

2. High Performance: Recognized as one of the most powerful Stirling engines on the market, it amazes with its operational sound and power, reaching speeds of 1300 to 1500 RPM.

3. Solid and Stable: This four-cylinder Stirling engine is significantly larger and heavier (5.2 lb) than typical models, ensuring stable operation.

4. Robust and Finely Crafted: Essential parts are made from SUJ2 alloy steel/bearing steel with a precision of up to 0.002mm. The engine features 16mm power cylinders, 16mm stroke power pistons, and 20mm hot cylinders, along with a quartz glass cylinder for enhanced observation.

5. Versatile Gift Choice: An excellent gift for various applications, including kids' science projects, physical/mechanical learning, and as a teacher’s demo prop. Its elegant packaging makes it an appealing gift for friends, family, and students.

Operating Instructions:

• Ensure the engine model is horizontally positioned. Manually toggle the flywheel to check for smooth operation.
• Use 95% purity alcohol for fuel. Fill the alcohol lamp to less than two-thirds.
• Ignite the alcohol lamp, ensuring safety, and start the flywheel to commence operation.
