Single-cylinder engine · Exploded view drawing
Exploded view drawing of a small single-cylinder engine on a technical drawing sheet. Eleven numbered parts are pulled apart along the cylinder axis in assembly order, from the crankcase at the bottom through the crankshaft, cylinder block, connecting rod, piston and pin, head gasket, cylinder head and valves, to the spark plug and head cover on top, with dash-dot explode lines, a parts list with quantities and materials, an assembled view, notes and a title block.
