WANKEL ENGINE ANIMATION
The Wankel radial engine is a fascinating beast that features a very clever rearrangement of the four elements of the Otto cycle. Felix Wankel was born in 1903 in Lahr in the Schwarzwald in Germany. He was employed in the sales department of a scientific publishing house in Heidelburg from 1921 to 1926. In 1924, he set up a workshop in Heidelburg where he made his first models of a rotary piston engine.
Realizing that the principal problem with such designs was gas tightness, he spent considerable time attempting to resolve it. By 1927, the problems were largely solved. During World War II, he worked for the German Luftfahrtministerium (Air Ministry). In 1951, Wankel and NSU signed a contract establishing a partnership to develop the rotary piston engine.
