Sectioned model of a single-cylinder, 4-stroke engine with a water cooling system. Equipped with a centrifugal pump and a mechanical-type converter, the engine operates electrically at 220 volts and runs at a reduced speed for clear observation of its mechanical components. The model includes professionally painted sections, differentiated by colors for easy identification of parts like the lubrication circuits, fuel system, and cooling system. Key components are chromium-plated and galvanized for durability and longevity.
