The purpose of this paper is to explain the history of the Diesel engine. It includes who invented the diesel engine, where it was invented and why it was invented. Also included is an explanation of what the Diesel engine was used for at the time of invention compared to what it is used for now. How the engine has changed over the years and why it changed as well as the effects, both positive and negative, will all be explained. Rudolph Diesel invented the Diesel engine in 1892. ... In response to the heavy resource consumption and the inefficiency of the steam engine, Diesel decided to develop his idea of a heat engine. ... Diesel envisioned an engine in which air is compressed to such a degree that there would be an extreme rise in temperature. ... For reference, the current day Four-Cycle Diesel Engine works with four strokes. ... In 1892, when the Diesel engine was invented, gasoline engines (spark-ignition) were already in existence. However, the Diesel engine would become a great improvement over the gasoline engine for many applications. ... The lack of an ignition system makes the Diesel a more elementary engine design. There are fewer components to maintain or fail on a Diesel engine due to the elimination of the spark plugs, spark plug wires, distributor cap and rotor, ignition coil and electronic-ignition module. ... Another advantage of the Diesel engine is that the diesel fuel or diesel oil is less expensive to produce than gasoline. ... The Diesel engine also achieves better fuel economy than a gasoline engine because diesel fuel has more energy per gallon than gasoline allowing Diesels to run leaner by mixing less fuel with the air. Therefore the engine is more efficient with the fuel it does burn. A Diesel engine can reach a thermal efficiency of forty percent or more. The best gasoline engine only uses twenty-five to thirty percent of the energy to turn the engines crankshaft. The rest of the heat is wasted and must be dissipated by the engine’s cooling system. Next, the history of the engine is explored. ... Later, Diesel was granted a patent in the United States for his engine. In 1892, Rudolph wrote a manuscript called “The theory and construction of a rational heat engine to replace steam engine and contemporary combustion engine”. This described his theory of a heat engine with an estimated seventy to eighty percent efficiency compared with the six to ten percent efficiency of the steam engine. ... The first Diesel engine ran on December 31st off of cheap kerosene for fuel. The engine was a single cylinder, water-cooled, fuel injected model. ... 2 % efficiency, an obvious increase in efficiency from the steam engine. In 1897, Rudolph ran the first diesel engine suitable for practical use, which operated at an unbelievable efficiency of seventy-five percent. “Diesel demonstrated his engine at the Exhibition Fair in Paris, France in 1898. The engine stood as an example of Diesel’s vision because it was fueled by peanut oil- the original biodiesel. Diesel thought that the utilization of a biomass fuel was the real future of his engine. He hoped that it would provide a way for the smaller industries, farmers, and “commonfolk” a means of competing with the monopolizing industries, which controlled all energy production at that time, as well as serve as an alternative for the inefficient fuel consumption of the steam engine. ... As the Diesel engine slowly gained popularity, ships and submarines benefited greatly from the efficiency of this new engine. ... Throughout 1892-1897 Diesel struggled to produce an engine that would run, a struggle that took place inside a large steam-engine factory in Augsburg. ... He even kept thousands of indicator diagrams, so that one can still tell how the engine was doing on any given day. ... “In order to make his engine work, Diesel had to: (1) compress air to a very high pressure and temperature, (2) choose the right fuel, (3) inject the fuel into the high-pressure air, (4) control the timing of the injection and the amount of fuel injected (in very small amounts, under very high pressure, in pulses), (5) mix the fuel with air in the very short time available, and (6) ignite the mixture. ... Due to the explosive growth of the Diesel engine, Rudolph established a company to manage the licensing of the design.
