Mini Metal Four-Stroke Internal Combustion Engine Model for Educational Experimental Science Demonstration
Features:
.Tribute to the Classic: Pay tribute to the first four-stroke internal combustion engine. This lightweight and exquisite engine model adopts a single-cylinder, four-stroke, 2-valve, dual camshaft pushrod structure, making it a captivating mini handheld craftwork.
.Fine Craftsmanship: Made entirely of metal, with an aluminum alloy base and high-quality metal parts, the model has a strong mechanical feel and a deep impression. You can get knowledge about the fascinating world of physical-mechanical engineering while playing with it.
.Realistic Operation: It is not just a decorative model, but also a simulation dynamic model that can simulate the operation of a real engine. Rotating the flywheel manually moves the piston and the intake valve timing corresponds to the exhaust valve timing. The visualized working process makes the working principle clear at a glance.
