Description

This model shows the internal structure and operating principles of a Wankel engine. This model is cut away to show the internal constructional details. Unlike other engines, the rotary piston engine avoids reciprocating parts. The power piston is an arch-like triangular rotor, which upon rotation, generates an epitrochoid. Hand powered motion (supplied through a crank) demonstrates the moving parts of the engine as the hand crank is rotated. A simulated spark plug uses a small lamp to indicate the firing point. Wankel engine model is solidly constructed out of aluminum and plastic. Large model measures 8 x 7 x 3-1/2 inches and is mounted on an 8 x 8 x 2-1/2 inch base. A placard on the base labels all key components. Model is perfect for classroom demonstration or as a gift for the car enthusiast! Lamp requires 2 AA batteries (not included).
