Adolf Schnürle

Adolf Schnürle (* May 24, 1897 ; † November 10, 1951 ) was a German engineer . He received his doctorate in 1924 at the Technical University of Stuttgart on the subject of "Theoretical-thermal investigation of a new process for converting heat into useful mechanical work when using solid fuel". In 1925 he developed the three-channel reverse flush for two-stroke diesel engines for his employer, Klöckner-Humboldt-Deutz A. G. ("KHD") . The patent revolutionized from 1934 in which licensees DKW in a further development of the two-stroke engine .

Schnürle then began developing diesel aircraft engines at KHD in 1935 , which were to compete with the opposed piston two-stroke diesel aircraft engines from Junkers .

Before and during the Second World War , Schnürle had his own company ( Adolf Schnürle Motorenkonstruktion / Stuttgart ), in which he continued to work on the development of the two-stroke diesel engine and for KHD until 1940 an 8-cylinder radial engine , the DZ 700 , a 16-cylinder Boxer engine , the DZ 710 and a 32-cylinder H engine developed by the DZ 720 . There were also individual flight attempts, but the development was then canceled.

There is a Dr.-Ing. Adolf and Gertrud Schnürle Foundation at the Protestant theological faculty of the Eberhard Karls University in Tübingen .
