Kurt Neumann (engine builder)

from Wikipedia, the free encyclopedia

Kurt Neumann (born December 31, 1879 in Dresden , † March 17, 1953 in Hanover ) was a German engine builder.

Life

Kurt Neumann studied mechanical engineering at the TH Dresden . Here he joined the Corps Teutonia . From 1905 he was assistant to Richard Mollier and in 1908 he was awarded a doctorate degree with his dissertation on the investigation of the work process in vehicle engines. PhD. In 1912 he completed his habilitation in theoretical machine theory with the text The processes in the gas generator based on the second law of thermodynamics .

In 1912/13 he worked in the diesel engine department of MAN in Nuremberg. During the First World War he served in the inspection of the motor vehicle troops in 1917/18.

In 1917 he was appointed associate professor for heat management and special areas of mechanical engineering at the TH Dresden. Together with Max Jakob (1883–1940) he investigated the ignition speed of gasoline and recognized the importance of the reaction speed of the combustion process for engine properties.

In 1920 the TH Hannover appointed him professor for technical heat theory, combustion and refrigeration machines. He founded the Institute for Combustion Engines and Technical Thermal Science. For the diesel engine , he researched fuel pressure injection and examined all work processes on a thermodynamic basis. He wanted to get closer to the gasoline engine at high speeds. In 1925 he was the first to calculate the evaporation process in the cylinder, where he found out that with high-speed runners, the charge must burn many times faster in order to maintain high machine performance. After all attempts with heavy oil gasifiers had failed, in 1927 he tested the four-stroke diesel with direct injection developed by Hermann Dorner . To increase the rate of combustion, he used charging and flushing of the cylinder. From 1930 he also examined the medium pressure engine with spark ignition.

In November 1933 he signed the German professors' confession of Adolf Hitler .
