MODEL ENGINE [2-stroke]: Gas engine, Hand-driven
- This Model Engine shows the internal structure and operating principles of an air cooled two-stroke engine.
- A cross section of the carburetor is shown. Hand powered motion supplied through a crank demonstrates the moving parts of the engine.
- The crank shaft and piston cycle through the stages of the two-stroke process as the hand-crank is rotated
- A simulated spark plug uses a small lamp to indicate the firing point.
- Solidly constructed out of aluminum and plastic.
- This large model measures approx. 265 x 165 x 120 mm and is mounted on a base approx. 200 x 200 x 60 mm.
- A placard on the base labels all key components.
- Lamp requires 2 AA batteries (not included).
(Wikipedia excerpt: …”A model engine is a small internal combustion engine[1] typically used to power a radio-controlled aircraft, radio-controlled car, radio-controlled boat, free flight, control line aircraft, or ground-running tether car model.
Because of the square–cube law, the behaviour of many engines does not always scale up or down at the same rate as the machine’s size; usually at best causing a dramatic loss of power or efficiency, and at worst causing them not to work at all. Methanol and nitromethane are common fuels.
