This industrial-grade Stirling engine is a marvel of modern engineering, designed as an all-metal exquisite model. With over 150 small parts, including 12 rolling bearings and 30 stainless steel bolts, this unique and innovative engine is a novel fashion gift and a prized collectible.


High-Power Design: The engine adopts a T-shaped rocker crank α structure, renowned for its high power and speed capabilities.

Low Friction: All moving parts are embedded with rolling bearings, ensuring low friction and smooth operation.

Precision Craftsmanship: The cylinder piston is made of SUJ-2 alloy steel, precision-ground for high clearance accuracy, hardness, and wear resistance.

Robust Construction: All connections are secured with screws, with copper pads sealing each joint, providing reliable performance and high-temperature resistance.

Efficient Heat Exchange: Equipped with a high-density aluminum alloy heat sink, the engine boasts an elevated heat exchange rate. The base features double-layer spring shock absorption for smoother operation.

Premium Materials: Constructed from 6061 CNC-machined aluminum alloy, the engine’s parts are sandblasted and oxidized for a durable and attractive finish.

Instructions for Use and Maintenance:
1, Before use, dial the flywheel to check whether it rotates smoothly, if there is excessive resistance, check if the cylinder is blocked by sludge, and if necessary, remove the cylinder assembly and wipe the piston and cylinder with alcohol. And apply graphite lubricant on the surface of the piston;
2, Inject 95% alcohol into the alcohol lamp (capacity is less than two-thirds), then ignite the alcohol lamp and place it under the heating cylinder to heat for 40 seconds (the flame should be in the heating zone as much as possible) , At last you can rotate the flywheel at high speed

Warning Tips:
1, The heating source will cause the body to generate high temperature during operation. Do not touch the high temperature parts such as the heating cylinder and heat sink, otherwise it will cause thermal burns;
2, Use only ordinary alcohol lamp heat sources, and do not use windproof lighters. And other high-temperature dark fire heaters (above 500 ° C), otherwise it will cause damage to the piston cylinder at high temperature and high speed operation;
3, Do not apply any lubricating liquid grease to the piston cylinder, otherwise it will cause excessive resistance and fail to work;
4, The machine has a starting compression force. It is recommended that novices use the engine base to start for the first time use, which is easier to control.
