The Smithsonian Motor-Works lets you build a real working battery powered four-cylinder model engine with real lights and sounds. Watch the spark plugs fire and the valves open and close.

It features simple screw-together parts, exhaust and intake valves, crankshaft, cams, crankcase, timing belt, cylinder block, exhaust manifold, head gasket, fan belt, engine mounting stand for display and screwdriver.
