Very rare booklet, of which no copy is recorded in the public collection on OCLC, by the inventor of the eponymous internal combustion engine Rudolph Diesel (1858-1913). After obtaining a patent in 1893, he developed a prototype of his engine in 1897 with the financial support of Heinrich von Buz, director of the MAN factory in Augsburg. The first commercially available engine, which was quite efficient for its time, was presented in 1900 at the Universal Exhibition in Paris. It was made truly efficient with the invention of the injection pump in 1924 by Lucien-Eugène Inchauspé. The first passenger cars with diesel engines were a Mercedes in 1936, then the Peugeot 402 in 1938. The low fuel cost of this engine also made it particularly interesting from an economic point of view for naval propulsion.
Rudolph Diesel declared, around 1911-1912, that his engine could be "fuelled with vegetable oils and will be able to make a strong contribution to the development of agriculture in the countries that will use it", predicting that "the use of vegetable oils as a liquid fuel for engines may seem insignificant today", but that "these oils will soon become as important as oil and coal tar" .
