Langen, Eugen

 

Born Oct. 9, 1833, in Cologne; died there Oct. 2, 1895. German engineer; one of the inventors of the internal combustion engine.

Together with another German inventor, N. Otto, Langen developed a silent gas engine, which became known and accepted after the Paris Exposition of 1867. The efficiency attained by the engine was 14–15 percent, significantly exceeding that of other, similar engines.
