Rudolf Christian Karl Diesel is a German engineer , born the March 18th 1858 with Paris and disappeared in the night from the September 29th with the September 30th 1913 at the time of a crossing of the English Channel.
Educated with Munich, it obtains a post of engineer in a factory for refrigerating machines. During the last decade of the XIXe century, it develops the idea of an engine with lighting by compression. It receives a patent for this process on February 23rd, 1893. At the beginning of 1897, whereas it is employed with the factory MAN with Augsburg, it builds a functional prototype, which will become “diesel engine”.
Its patent is deposited under the name of “engine with heavy oil”, because it is with this product that it functioned. Heavy oils were residues of the distillation of crude oil after extraction of the products used at the time: very small little gasoline, much oil paraffin and products of greasing (oils and greases).
The first marketed engine had rolled one of cubic DM turning to 172 tr/min and developed a power of 14.7 kw. In spite of its system of injection per air pump, this engine had a rather interesting output: CSE (specific consumption) of 335 g/kWh (as example, weight-heavy the most recent has a CSE between 250 and 200 g/kWh). It is the French Lucien-Eugene Inchauspé (1867-1930) who, in 1924, by inventing the injection pump, made some a powerful engine. And the production by Robert Bosch allowed a fast development of these engines. The first cars of tourism to diesel engine were a Mercedes in 1936, then Peugeot 402 in 1938.
In 1903, a named barge " Small Pierre" is been driven by an engine of the " type; Diesel" , built by Sautter-Merganser, and adapted by Frederic Dyckhoff. It sails successfully on the channel of the Marne in the Rhine. In June 1897 had been created, with seat in Bar-le-Duc (Meuse), the " French company of the diesel engines with combustion intern" , with the capital of 1.200.000 francs, of which the half of the partnership shares allotted to Rudolph Diesel remunerated its contributions in industry.
Between 1911 and 1912, he declares that “the diesel engine can be fed with plant oils and will be able to strongly contribute to the development of the agriculture of the countries which will use it” and predicts that “the use of plant oils as carburizing for engines can seem unimportant today”, but that “these oils will become soon as important as the oil and the tar of coal”.
He disappears in mysterious circumstances on a ferry. Many assumptions were put forth on this disappearance, being a German engineer, author of an invention already recognized like major and therefore to work in England for admiralty whereas the international tensions which will lead to the First World War were already expressed.
