Hugo Güldner
Carl Hugo Güldner (18 July 1866 – 12 March 1926) was a German engineer and inventor. He is best known for inventing the two-stroke diesel engine, and the Valve_timing#Valve_overlap, valve overlap in internal combustion engines. Life and career Güldner was born in Herdecke, south of Dortmund. He attended the ''Höhere Maschinenbauschule'' (mechanical engineering college) in Hagen, and worked as an engineer in Magdeburg throughout the 1890s. In 1891, Güldner married Adele Benecke, with whom he had two sons and two daughters.Allen D. Gebus: ''World Who's who in Science: A Biographical Dictionary of Notable Scientists from Antiquity to the Present'', Marquis-Who's Who, 1968, p. 719 In Magdeburg, Güldner invented several devices related to internal combustion engines, and he also worked as an editor for the "Der Monteur" magazine. In 1894, Güldner contracted with the Schumann & Küchler factory in Erfurt; however, they never built any engines or devices based upon Güldner's ...

Herdecke
Herdecke () is a town in the district of Ennepe-Ruhr-Kreis, North Rhine-Westphalia in Germany. It is located south of Dortmund in the Ruhr Area. Its location between the two Ruhr reservoirs Hengsteysee and Harkortsee has earned it the nickname ''Die Stadt zwischen den Ruhrseen'' (lit. ''The city between the Ruhr lakes''). The city is located in the area of the Regionalverband Ruhr (RVR). The two Ruhr lakes as well as the forests on the Ardey heights make the town attractive to tourists. The historic center with its many half timbered houses and the 30-metre-high railway viaduct across the Ruhr valley are two more landmarks. Geography Herdecke is located at the foot of the Ardeygebirge, the northwestern part of the Sauerland, between Dortmund in the North and Northeast, Hagen in the South, Wetter (Ruhr) in the Southwest and Witten in the West and Northwest. Herdecke lies between 80 and 274 meters above sea levels. It lies on the north bank of the river Ruhr, between the Harkort ...

19th-century German Engineers
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moritz Schröter
Maximilian Moritz Schröter (25 February 1851 – 12 March 1925) was a German industrial engineer and university professor of thermodynamics and the theory of machines. Life and career Moritz Schröter was the son of Moritz Schröter, who himself was a university professor. After his father′s death in 1867, Gustav Zeuner became the guardian of 16-year-old Schröter. After finishing the Gymnasium (school), Gymnasium in Zürich, Schröter studied at the ''ETH Zurich, Polytechnikum Zürich'', where he was awarded a diploma in engineering. From 1873 to 1876 he worked in the locomotive factory ''Georg Sigl'' in Wiener Neustadt. He then returned to Zürich, to become the university assistant of Georg Veith. In 1879, Schröter became a professor of theory of machines at the Technical University of Munich, where he built a new laboratory for machine design. From 1908 to 1911, he was the university's rector. Schröter helped designing four important machines in engineering history: the ...

Motor 250/400
The Motor 250/400 is the first functional diesel engine. It was designed by Rudolf Diesel, and drawn by Imanuel Lauster. The workshop of the Maschinenfabrik Augsburg built two units, the ''A-Motor'', and the ''B-Motor''. The latter has been on static display at the Deutsches Museum in Munich since testing it came to an end. Throughout the late 1890s, several licensed copies of the ''Motor 250/400'' were made. Most of these copies were very unreliable, which almost caused the diesel engine's demise. History Development In early 1893, Rudolf Diesel had contracted with both Maschinenfabrik Augsburg and Krupp in Essen to develop an engine based on his essay Theory and Construction of a Rational Heat Motor. However, by mid-1893 Diesel had realised that the rational heat motor would not work, and he modified his design. This modified design would later be known as the diesel engine. The first prototype, ''Motor 150/400'', was completed on 12 July 1893. Initial tests with it prov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Friedrich Sass
Friedrich Sass (6 January 1883 – 26 February 1968) was a German engineer, university professor and historian. Life and career Friedrich Sass was born in Koldenbüttel and attended the ''Gymnasium'' (grammar school) in Schleswig. He studied mechanical engineering at the Technical University of Munich, and marine engineering at the Technical University of Berlin. After graduating from TU Berlin, Sass worked as a steam turbine designer at AEG from 1908. During World War I, Sass became the head of AEG's Diesel engine department, where he designed the double-acting piston two-stroke Diesel engine with air-blast-less, direct fuel injection; initially, it was intended for submarine use. In the 1920s, Sass continued his work on direct fuel injection systems; he was the first engineer to study the relation between the diameter of a fuel spray at the point of injection, and its cylinder intrusion. In 1940, Sass stopped working for AEG. From 1927, Sass had been an untenured prof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imanuel Lauster
Imanuel Lauster (28 January 1873 – 15 March 1948) was a German engineer and businessman, who designed the first Diesel engine for Rudolf Diesel, and served as the head of M.A.N.'s board of directors from 1932 to 1934. Life and career Lauster was born in , a small municipality then just to the north-east of Stuttgart (into which it was subsumed in 1923). He lived a youth "full of privation". On 1 April 1888, he joined ''Gottlieb Kuhn Maschinen- und Kesselfabrik'' in Stuttgart-Berg. The firm's workshop did not need fitter apprentices at the time, therefore, Lauster was taught technical drawing at the design bureau before he started working as a fitter at the workshop in 1889. Later, Lauster also assembled steam engines, and tested them on a dynamometer. In 1891, Lauster was assigned to the newly founded internal combustion engine workshop of ''G. Kuhn'', where he had to build 6 PS and 8 PS Langensiepen engines with glowtube ignition. He was also responsible for demonst ...

Rudolf Diesel
Rudolf Christian Karl Diesel (, ; 18 March 1858 – 29 September 1913) was a German inventor and Mechanical engineering, mechanical engineer who is famous for having invented the diesel engine, which burns diesel fuel; both are named after him. Early life and education Diesel was born at 38 Rue Notre Dame de Nazareth in Paris, Second French Empire, France in 1858 the second of three children of Elise (née Strobel) and Theodor Diesel. His parents were Bavarian immigrants living in Paris... Theodor Diesel, a Bookbinding, bookbinder by trade, left his home town of Augsburg, Kingdom of Bavaria, Bavaria, in 1848. He met his wife, a daughter of a Nuremberg merchant, in Paris in 1855 and became a leather goods manufacturer there. Shortly after his birth, Diesel was given away to a Vincennes farmer family, where he spent his first nine months. When he was returned to his family, they moved into the flat 49 in the :fr:Rue de la Fontaine-au-Roi, Rue de la Fontaine-au-Roi. At the time, th ...
