Didactic Four Stroke-cycle Engine Demonstrator Finger Engine

Features:

This internal combustion engine model pays homage to the first four-stroke internal combustion engine in history using a single-cylinder, four-stroke, two-valve, double-cam ejector structure. It has a simple structure, is light and beautiful, and is a miniature work of art that you won't be able to put down.

All-metal refined, highly textured metal parts with a solid and outstanding mechanical sense may teach you about the fascinating physical and mechanical engineering world while playing. Sophisticated craftsmanship.

Simulated engine operation: This model is not simply decorative; it can also imitate the dynamic behavior of a genuine engine. The piston can be moved, the intake/exhaust valve timing matches, the engine's operation can be seen, and the basic operating principle is obvious while turning the flywheel by hand.

Education and Science Assembly: It effectively restores the OHV engine's operating principle and can be employed in instructional presentations. It is a handheld decompression toy for mechanical lovers and an excellent physical and mechanical instructional toy for kids simultaneously.

This model has been put together; do not take it apart at will. To protect the model from harm, refrain from playing violently. When finished using it, please store it carefully and pay close attention to cleaning and maintenance for more extended usage.
