Field notes
The model combines a parts catalog with an inspectable 3D assembly: visitors can search for components, switch to X-ray or exploded views, and follow the engine through four 180-degree strokes. Its inventory names 30 components, including four pistons, two overhead camshafts, four spark plugs, and sixteen valve springs, while the page describes the complete model as 51 assemblies. JavaScript is required for the interactive exploration.
