Eisco 4-Stroke Gas Engine Model
This model shows the internal structure and operating principles of a water-cooled four-stroke engine. As the handcrank is turned, the model’s crank shaft, piston, valves, and cams cycle through all the stages of the four-stroke process. A simulated spark plug utilizes a small lamp to illustrate the firing point. The model also shows a cross section of the carburetor. Constructed of aluminum and plastic, the model features a placard on the base that identifies all key components.
