Wolf-Dieter Bensinger (26 February 1907 – 17 June 1974) was a German engineer and university professor who contributed significantly to the development of the Wankel rotary engine.

Life and career

Bensinger was born in Donaueschingen in 1907.[1]

In 1931, Bensinger became head of development at Deutsche Versuchsanstalt für Luftfahrt (DVL) in Berlin.[2] At DVL, he developed a sleeve valve system for the Daimler-Benz DB 600.[3] On 20 October 1934, Bensinger married Ilse Margarete Anna, who originated from Stargard, Pommern. Their son was born in 1936.[4] In the 1930s he met Felix Wankel, who became a long-term friend, and with whom Bensinger had a strong bond of trust.[5]

From 1943[6] or 1944 Besinger worked as an engineer with Daimler-Benz AG in Stuttgart[1] where he became head of New Engine Development. From 1945, Bensinger became head of Passenger Car Engine Development.[2] He designed engines such as the six-cylinder Mercedes-Benz M 180 Otto engine (later used in the Mercedes-Benz W 187 series Type 220),[7] and he contributed to the design of the Mercedes-Benz M 198 Otto engine used in the Mercedes-Benz W 198 series Type 300 SL.[8] In 1959, Bensinger became a procurator with Daimler-Benz AG, and from 1963, he was the leading engineer in Daimler-Benz's passenger car engine development.[2]

In 1960, Bensinger began Wankel engine development at Daimler-Benz,[9] without having a written licence agreement with Wankel or NSU; Bensinger and Wankel, who were friends, had a verbal agreement.[7] Eventually, the licence agreement was signed on 26 October 1961.[8] In 1971, Bensinger received and offer of a professorship at the University of Stuttgart.[10] Contemporaries considered Bensinger a Wankel engine enthusiast.[11]
