4-Stroke Gasoline Hand-Crank Engine Model, 13.75"

This Eisco Labs 4-stroke gasoline engine model demonstrates the operating principles of an internal combustion engine through actuating moving parts. Standing 13.75 inches tall, the model is constructed from cast alloys and ABS plastic for years of classroom use. Functional moving parts include the crankshaft, camshaft, drive gear, timing gear, connecting rods, piston, intake and exhaust valves, rocker arms, push rods, throttle valve, and float. An ignition light powered by 2 AA batteries (not included) illuminates during the compression stroke. Ideal for automotive technology, physics, and engineering classrooms demonstrating intake, compression, power, and exhaust strokes.
