The diesel engine has a long history that is intertwined closely with economic and other issues of the time. The diesel engine 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 piston 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 no where close to 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 an efficiency of approximately 26%. 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 a diesel engine 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 was 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.
In the 1920’s the engine was redesigned into a smaller and more compact version. This allowed it to be used for a wider range of applications and even in the automobile industry. The development of the diesel engine continued and it was made better and better by other inventors such as Clessie L. Cummins who worked out many of the bugs of the diesel engine such as those concerning size and weight as well as the instability of the fuel system.
The diesel generator owes its roots to mainly two inventors. One of these is the creator of the first generator Michael Faraday and the other is the creator of the diesel engine Rudolph Diesel. The first of these two has contributed greatly to life as we know it today with all his discoveries in electricity.
Michael Faraday was of humble beginning but always had a curious nature. He was at an early age an errand boy for a bookbinding shop and here he vastly increased his knowledge as he read anything he could put his hands on. He was very interested in the concept of energy and force and this interest is one that continued throughout his life and eventually he developed into a famed chemist and physicist.
It was his discovery of electromagnetic induction in the year 1831 that led to the development of the modern generator. He used what he termed his induction ring to discover the electromagnetic induction. This was the generation or induction of electricity in a wire by the use of the electromagnetic effect of the current in another wire. This was the first transformer and followed closely with the discovery of the magneto-electric induction process which is the production of a steady electric current.
He attached two pieces of wire by the use of a sliding contact to a copper disc. He rotated the disc through the poles of a magnet and was able to generate continuous direct current. This was the first generator of time. This group of experiments led to the revolutionized generator that we know today.
The diesel generator however owes its development to the inventor Rudolph Diesel. He started off as a refrigerator engineer and eventually found himself working on many heat engine designs. He in 1892 put out a patent that dealt with the method and design of a engine where combustion would take place in the cylinder. He continued to work to this goal and was successful in the production of a diesel engine that produced an efficiency of 75%.
It is the coupling of his diesel engine with the generator that led to the diesel generator that we known today. His design was rather large and very heavy and found more use in industrial applications as a generator. They were used to power pipelines and for electric plants and water plants. Later on they found applications in the mines and in oil fields. The diesel generator is simply the coupling of the diesel engine with an electrical generator and has been use throughout history since its invention for many applications.
The diesel generator has been seen to be the choice of many of the larger companies as it is well suited for industrial use. A major discouraging factor for its use in terms of the retail market has been the fact that it can be rather noisy but this has been reduced greatly from the first diesel generators and is now almost comparable to the gasoline generators. These generators also offer other perks such as increase fuel economy and reduced maintenance costs which can explain their popularity in industrial applications.
