MODEL ENGINE: 4-Stroke Diesel Engine, Hand driven | Useful in scientific applications

$ 153.40 excl. GST

Model Engine.

This Model Engine 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. he 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 approx. 300 x 225 x 125 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 a 6-12 V power source (not included).

(Wikipedia excerpt:  “…A four-stroke (also four-cycle) engine (E) is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.).

In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston…”)
