Otto, Nikolaus August

(nē`kōlous ou`go͝ost ô`tō), 1832–91, German engineer. He was coinventor (1867) of an internal-combustion engine, and he devised (1876) the four-stroke Otto cycle, which was widely adopted for automobile, airplane, and other motors.

Otto, Nikolaus August

Born June 10, 1832, in Holzhausen, Nassau; died Jan. 26, 1891, in Cologne. German designer and entrepreneur.

After graduating from a Realschule in 1848, Otto was involved in commercial activities. Jointly with the German engineer E. Langen, he developed an air-standard engine in 1867. He also built an improved four-stroke gas engine in 1876 using the idea of the four-stroke compression cycle proposed in 1862 by the French engineer A. Beau de Rochas. In 1884, Otto suggested the use of an electric ignition, which made it possible to use a liquid fuel for the engine.
