Rudolf Diesel was born in Paris in 1858. His parents were Bavarian immigrants. Rudolf Diesel was educated at Munich Polytechnic. After graduation he was employed as a refrigerator engineer. However, he true love lay in engine design. Rudolf Diesel designed many heat engines, including a solar-powered air engine. In 1893, he published a paper describing an engine with combustion within a cylinder, the internal combustion engine. In 1894, he filed for a patent for his new invention, dubbed the diesel engine. Rudolf Diesel was almost killed by his engine when it exploded. However, his engine was the first that proved that fuel could be ignited without a spark. He operated his first successful engine in 1897.
In 1898, Rudolf Diesel was granted patent #608,845 for an "internal combustion engine" the Diesel engine.
The diesel engines of today are refined and improved versions of Rudolf Diesel's original concept. They are often used in submarines, ships, locomotives, and large trucks and in electric generating plants.
Though best known for his invention of the pressure-ignited heat engine that bears his name, Rudolf Diesel was also a well-respected thermal engineer and a social theorist. Rudolf Diesel's inventions have three points in common: They relate to heat transference by natural physical processes or laws; they involve markedly creative mechanical design; and they were initially motivated by the inventor's concept of sociological needs. Rudolf Diesel originally conceived the diesel engine to enable independent craftsmen and artisans to compete with large industry.
At Augsburg, on August 10, 1893, Rudolf Diesel's prime model, a single 10-foot iron cylinder with a flywheel at its base, ran on its own power for the first time. Rudolf Diesel spent two more years making improvements and in 1896 demonstrated another model with the theoretical efficiency of 75 percent, in contrast to the ten percent efficiency of the steam engine. By 1898, Rudolf Diesel was a millionaire. His engines were used to power pipelines, electric and water plants, automobiles and trucks, and marine craft, and soon after were used in mines, oil fields, factories, and transoceanic shipping.
Rudolf Diesel
Rudolf Diesel was the inventor of the diesel fueled internal combustion engine.
History of the Diesel
In 1892, Rudolf Diesel was issued a patent for a proposed engine, in which air would be compressed so much that the temperature would far exceed the ignition temperature of the fuel.

In 1892 Rudolf Diesel was issued a patent for a proposed engine that air would be compressed so much that the temperature would far exceed the ignition temperature of the fuel. Baron von Krupp and Machinenfabrik Augsburg Nurnberg Company in Germany backed Rudolf Diesel financially as well as providing engineers to work with him on the development of an engine that would burn coal dust, because there were mountains of useless coal dust piled up in the Ruhr valley. The first experimental engine was built in 1893 and used high pressure air to blast the coal dust into the combustion chamber. This engine exploded and further developments of using coal dust as a fuel failed, however a compression ignition engine that used oil as fuel was successful and a number of manufacturers were licensed to build similar engines.
The original oil burning engines used very crude mechanical injection equipment so Rudolf Diesel again began using air blast to provide atomization of the fuel as well as turbulence of the mixture. This was very successful and utilized in Rudolf Diesel's third engine built in 1895. This engine was very similar to engines�being used today. It was a four-stroke cycle with 450psi compression. Progress in diesel engine development has since depended on improvements in fuel injection technology.
In 1922 Robert Bosch began the development of a fuel injection system for the diesel engine. By 1927 they finally had an acceptable injection pump. The demand for this pump was so great that Bosch in Germany was unable to keep up. In 1931 agreements were made with companies in France and England to produce injection pumps. In 1934 a company in the U.S. began manufacturing under the name of American Bosch and in 1938 the Diesel Kiki company in Japan was founded. Since then licenses have been granted to numerous manufacturing companies in several countries, most of which us Robert Bosch's designs to build injection pumps.
