Working Mini Single-Cylinder Engine Model - 4-Stroke Gasoline Engine Kit For Adults

About This Product

Okay, this working mini engine model is absolutely fascinating for anyone who loves mechanics or engineering! This isn't just a display piece - it's a fully functional single-cylinder four-stroke gasoline engine that actually runs. The craftsmanship is incredible, made from brass, aluminum alloy, and stainless steel using CNC machining for precision. It's got a 2.1CC displacement with a 13mm cylinder diameter and air-cooled system, just like a real motorcycle engine but in miniature form. Starting it up is done with a pedal start, and it needs 4.5V from 3 AA batteries (not included) for the igniter. The whole thing sits on a nice wooden base that keeps it stable while running. Each fuel tank gives you about 15 minutes of operation, which is perfect for demonstrations or just admiring the engineering. At 900 grams with dimensions of 11x8x11cm, it's substantial enough to feel quality but compact enough for desktop display. This isn't a kids' toy - it's a serious physics science experiment that's perfect for adults, students, or anyone fascinated by how engines work. The attention to detail is amazing, from the materials to the way it operates. Whether you're a mechanical engineer, automotive enthusiast, teacher, or just someone who appreciates finely crafted working models, this engine is absolutely mesmerizing to watch in action. It makes an incredible conversation piece and educational tool that actually demonstrates internal combustion principles in real time.
