Product Description

A vintage model and teaching aid, a rare item and an interesting display piece for anyone interested in engineering.


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 epitrechoid.


The Wankel engine  is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion. In contrast to the more common reciprocating designs, the Wankel engine delivers advantages of simplicity, smoothness, compactness, high revolutions per minute and a high power-to-weight ratio.  All parts rotate moving in one direction, as opposed to the common reciprocating piston engine which has pistons violently changing direction. The four stroke cycle occurs in a moving combustion chamber between the inside of an oval-like epitrochoid-shaped housing, and a rotor that is similar in shape to a  reuleaux triangle  with sides that are somewhat flatter.


Hand powered motion supplied through a crank demonstrates the moving parts of the engine as a handcrank is rotated.


A simulated spark plug uses a small lamp to indicate the firing point.


Approximate size 30cm wide x 35cm deep x 18cm deep
