Demonstrational Section Working Model of 2 Stroke Petrol Engine
A cut-section working model of a 2-stroke petrol engine to demonstrate porting, crankcase compression, and carburetion.
Overview
The Demonstrational Section Working Model of the 2 Stroke Petrol Engine provides a visual cut-section display of a small 2-stroke spark-ignition engine used in mopeds, chainsaws, and outboard motors. The model clearly shows the crankcase, transfer ports, exhaust ports, carburettor, spark plug position, and piston crown shape, with slow-rotation electric motor drive. Students observe how the piston simultaneously acts as a valve controlling port opening, and how the crankcase pre-compression feeds the fresh charge. The model is a fundamental teaching aid for understanding simple 2-stroke cycle engines and their design differences from 4-stroke counterparts.
