*** WHAT IS STIRLING ENGINE *** 

Stirling engines are unique heat engines because their theoretical efficiency is almost equal to the theoretical efficiency, which is called the Carnot cycle efficiency.

The stirling engine generates power through gas expansion when heated and contraction when cold. This is an external combustion engine that continuously burns fuel, expands air (or helium or hydrogen) as a medium to move the piston, and cools the expanded gas in the cold cavity, repeating this cycle process

* The bracket design is vivid and hollowed out.
* Imported precision bearings ensure smooth rotation. Machined silver flywheel.
* All metal alcohol lamp, heat-resistant wick.
* All-metal hot cylinder, valve baffle and connecting rod are all made of high-quality stainless steel.
* The design concept is novel, the overall appearance is exquisite and fashionable, the best choice for gift collection!

*** ATTENTION ***

A. Start-up steps ***
1. Put the model on the horizontal surface; add some alcohol into the alcohol lamp
2. Light the alcohol lamp; turn the flywheel by hand until the flywheel can automatically rotate
3. In the process of start, move the alcohol lamp to let the model run to the best
4. The height of the alcohol lamp wick should be no less than 15 mm, and you can adjust the wick height to achieve the best operation.

B. Matters needing attention
1. When heating, do not touch with your hands cylinder and heating portion.
2. Avoid other liquid substances come into contact with cylinders in case of cylinder rustiness; extinguish alcohol lamp after finishing the demonstration.

C. Maintenance plans (if the model is not running very well)
1. Check if there is enough alcohol in the alcohol lamp.
2. Check if the small and big wheel jackscrews loose or not.
3. Too high temperature in the air cylinder because of the continuous heating for a period of time will affect the performance of the product.
4. Check the valve position: the highest position of the flapper valve (2) is to cover one fourth of the valve port. 
5. Check if the angle is correct or not: when the piston (7) lies in the innermost of the air cylinder, the small jackscrew (3) hole should be just facing the positioning port (6). If the position is wrong, please loosen the jackscrew; then tightly fix the jackscrew in the correct position.
