The diesel engine has a long history. It was created by Rudolph Diesel. He conceptualized the diesel engine and thought up the principle of its operation. He thought up the concept of the engine that compresses air to the degree where there is a resulting rise in temperature.

The concept followed the principle where when the air enters the chamber with the ring and pinion gear the air ignited due to the high temperatures. This causes the piston to move down and eliminates the need for an ignition source. When Diesel designed his engine it was in a time when there was a demand for a more fuel efficient engine as the steam engine was nowhere near efficient.

It was on February 27th, 1892 that Diesel filed a patent in the patent office in Germany for his method and design for the combustion engine. He sourced contracts from companies that manufactured machines and began his experimentation stage. During this stage he constructed working models of his design in an attempt to construct the most efficient engine of that time.

It was in the year 1893 that he was successful in putting out the first model that was able to run with its own power and with a high efficiency. This was more than double the efficiency of the steam engines of that time and was a great stride for the efficient engine and a great start to the engines of today.

It was in February of 1897 that he accomplished a great achievement and produced diesel engine parts that ran at 75% efficiency. This was the first one of its kind that was deemed suitable for practical use and was demonstrated at the Exhibition fair in France in the year 1898. This engine in particular was run on peanut oil and in Diesel’s vision was great for the small business owners as well as farmers as it used an economical fuel source that was a biomass fuel. It was his use of a biomass fuel that continued until the 1920’s and is starting again today.

In the past the diesel engine ring gears were not considered to be small enough for anything but use that was stationary in nature as they were very heavy and cumbersome. Common uses were on ships and industrial uses. Rudolph Diesel disappeared in 1913 and it was not certain whether he died a natural or unnatural death. Many thought his death was related to the politics of the time and the vast knowledge he possessed and was willing to share with enemies of the German government of the time.
