Eisco Four-Stroke Diesel Engine Model

Shows the internal structure and operating principles of a water-cooled four-stroke engine. The valves are clearly evident, cams being driven by a gear train from the rear of the main crank. This is the chain driven overhead camshaft type and all functional components (camshaft, rock-arms, tappets, etc.) are clearly demonstrated. The functioning of the fuel injection system is also represented. Cross sections of the carburetor and fuel supply are shown. Hand powered motion supplied through a crank demonstrates the moving parts of the engine. Crank shaft, piston, valves and cams cycle through all stages of the four-stroke process as the handcrank 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 12 x 9 x 5 inches and is mounted on an 8 x 8 x 2.5 inch base. A placard on the base labels all key components.
