Fully Assembled Stirling Engine Generator Model – STEM Engine for Educational and Scientific Exploration

Full Metal Stirling Engine Generator Model – STEM Engine Educational Toy

This Stirling engine is made with industrial-grade processing, creating an exquisite all-metal model that is both unique and innovative. It’s a novel and fashionable gift or collectible. The entire machine is assembled from over 150 small parts, including 12 rolling bearings and 30 stainless steel bolts.

Features:

The Stirling engine features a T-shaped rocker crank structure, providing high power and speed.

Rolling bearings support all moving parts, resulting in low friction.

The cylinder and piston are precision ground from SUJ-2 alloy steel, offering high precision, hardness, and wear resistance.

Corrosion-resistant copper pads seal all connection parts, ensuring high-temperature resistance.

Improved heat exchange is provided by a high-density aluminum alloy heat sink.

Shock absorption is enhanced by double-layer spring on the base, enabling smoother operation.

All components are made from durable metal materials, contributing to the engine’s compact size, long lifespan, and reliability.

Instructions for Use and Maintenance:

Before operating, ensure the flywheel rotates smoothly and that the cylinder is not clogged. If necessary, clean the piston and cylinder with alcohol and lubricate the piston with graphite lubricant.

Light the alcohol lamp (using 95% alcohol with a maximum fill of two-thirds) and heat the cylinder for approximately 40 seconds. Maintain the flame within the heating zone.

Rotate the flywheel steadily to achieve high speeds.

Warning Tips:

High temperatures are generated during operation, avoid touching the heating cylinder and heat sink. Thermal burns may occur.

Use only ordinary alcohol lamps. Do not use windproof lighters or other high-temperature heat sources as they may damage the piston and cylinder.

Avoid lubricating the piston with grease, as this may cause excessive friction and prevent proper operation.

Beginners are advised to start the engine using the provided engine base.
