This engine model is also a well-designed and well-made mechanical toy, suitable for people of all ages and all walks of life, and is an excellent birthday gift.

Simple operation, filled with 95% ethanol and ignited. After a few seconds of warm-up, the flywheel rotates quickly and smoothly, lighting up the LED bulb mounted on the small generator.

The shaft joint is connected by ultra-precision miniature bearings, which has good stability, no need for lubrication, and is easy to assemble. There is a soft rubber pad at the bottom for convenient desktop placement.

It can be used as a teaching tool to demonstrate how to convert energy (heat) into mechanical work. It has a visual texture and beautiful appearance, and is a good decorative ornament.
