Description:

Didactic Four Stroke-cycle Engine Demonstrator Finger Engine

Features:

.Tribute to the classic: Tribute to the first four-stroke internal combustion engine in history, this internal combustion engine model adopts a single-cylinder four-stroke 2-valve double-cam ejector structure, with a simple structure, light and exquisite, and is a mini-handcraft that you can't put it down.
.Sophisticated craftsmanship: All-metal refined, highly textured metal parts, strong and impressive mechanical sense, can bring you knowledge about the wonderful world of physical and mechanical engineering in the process of playing.
.Simulation operation: It is not only a decoration model, but also a simulation dynamic model that can simulate the operation of a real engine. Running the flywheel by hand, the piston is movable, the timing of the intake/exhaust valve corresponds, the working process of the engine is visualized, and the working principle is clear at a glance.
.Science and education Assembly: It truly restores the working principle of the OHV engine and can be used for teaching demonstrations. At the same time, it is also a decompression handheld toy for mechanical enthusiasts, and it is also a good physical and mechanical educational toy for children.
.This model has been assembled, do not disassemble at will. Do not play with violence to avoid damage to the model. Please keep it properly after use, and pay attention to cleaning and maintenance for longer use.
