Rudolf Diesel, father of our engines

There are few 4X4s that don’t have Rudolf Diesel’s namesake invention rattling away under the bonnet.

Practically every compression ignition engine owes it's design to Rudolph Diesel

This Toyota engine may be Japanese refined, but it all comes down to the Frenchman’s design

The inventor of the diesel engine, Rudolf Diesel, was born in France during 1858, later settling in England. His foray into the engineering world came after graduating from the Polytechnic of Munich where he received a scholarship in engineering. On completion of his studies, Diesel returned to France and began working with his former professor as a refrigeration engineer and later becoming the director of the plant they constructed together. While this sparked his love of engineering, his true passion revolved around inventing and designing engines.

To show just how passionate about the diesel engine he was, Rudolf published a paper in 1893 describing the workings of an engine that utilised internal combustion inside the cylinder, that did not rely on spark for combustion. The first of his engines was successfully operated in 1897, and this design was granted patent number 608,845 in 1898, that same year Rudolf Diesel made his first million dollars. That is just five years from concept to reality. It takes longer for automotive companies to develop engines now!

A diesel engine is able to be tuned to run on a variety of fuels, far more tolerant than a spark ignition engine. As well as mineral oil derived distillate (diesel) and biodiesel, a compression ignition engine will run on any hydrocarbon rich liquid. Alcohol, vegetable oil, aviation kerosene, even the really heavy bunker C is used in diesel engines, albeit pre-heated. Fuel delivery systems (injector pumps) have to be suited to the fuel too.

A long-lived invention by a short-lived man

Rudolf passed away under strange circumstances in 1913. His body was found dumped at sea after boarding and travelling on a post office steam ship to attend a meeting in London. It is believed he committed suicide while aboard, however there are many conspiracy theories that surround Rudolf Diesel’s death.
