The Otto engine was a large stationary single-cylinder internal combustion four-stroke engine designed by the German Nicolaus Otto. It was a low-RPM machine, and only fired every other stroke due to the Otto cycle, also designed by Otto. Three types of internal combustion engines were designed by German inventors Nicolaus Otto and his partner Eugen Langen. The models were a failed 1862 compression engine, an 1864 atmospheric engine, and the 1876 Otto cycle engine known today as the gasoline engine. The engines were initially used for stationary installations, as Otto had no interest in transportation. Other makers such as Daimler perfected the Otto engine for transportation use. |
