Mini Metal Mechanical DIY Single Cylinder Four-Stroke Double Overhead Valve Cam Pushrod Internal Combustion Engine Model Toy, Black Mini Metal Four-Stroke Internal Combustion Engine Model for Scientific Experiment Teaching
FEATURES:
TRIBUTE TO THE CLASSIC:Tribute to the first four-stroke internal combustion engine. This lightweight and exquisite engine model adopts a single-cylinder, four-stroke, dual-valve, dual-camshaft pushrod structure, making it a fascinating mini handheld craft.
EXQUISITE CRAFTSMANSHIP:Made of all metal, with an aluminum alloy base and high-quality metal parts, the model is full of mechanical sense and impressive. In the process of playing, you can gain an in-depth understanding of the wonderful world of physical mechanical engineering.
REALISTIC OPERATION:It is not just a decorative model, but also a simulated dynamic model that can simulate the operation of a real engine. Manually rotating the flywheel can drive the piston, and the intake valve timing corresponds to the exhaust valve timing. The visual workflow makes the working principle clear at a glance.
POPULAR SCIENCE AND EDUCATION:The working principle of the overhead valve engine is faithfully reproduced and can be used for teaching demonstrations. It is also a good helper for mechanical enthusiasts to relieve stress, and it is also an educational toy for children to learn physics and mechanical knowledge.
THIS MODEL HAS BEEN ASSEMBLED:Rotate the four legs at the bottom to open the base and install 2 AAA batteries. Do not place it with force to avoid damage. Please keep it properly and pay attention to cleaning and maintenance for long-term use.
