Though best known for his invention of the pressure-ignited heat engine that bears his name, the French-born Rudolf Diesel was also an eminent thermal engineer, a connoisseur of the arts, a linguist, and a social theorist. Diesel's inventions have three points in common: They relate to heat transference by natural physical processes or laws; they involve markedly creative mechanical design; and they were initially motivated by the inventor's concept of sociological needs. Diesel originally conceived the diesel engine as a facility, readily adaptable in size and costs and utilizing locally available fuels, to enable independent craftsmen and artisans better to endure the powered competition of large industries that then virtually monopolized the predominant power source-the oversized, expensive, fuel-wasting steam engine.

In 1892 Rudolf Diesel was issued a patent for a proposed engine that air would be compressed so much that the temperature would far exceed the ignition temperature of the fuel. Baron von Krupp and Machinenfabrik Augsburg Nurnberg Company in Germany backed Rudolf Diesel financially as well as providing engineers to work with him on the development of an engine that would burn coal dust, because there were mountains of useless coal dust piled up in the Ruhr valley. The first experimental engine was built in 1893 and used high pressure air to blast the coal dust into the combustion chamber. This engine exploded and further developments of using coal dust as a fuel failed, however a compression ignition engine that used oil as fuel was successful and a number of manufacturers were licensed to build similar engines.

The original oil burning engines used very crude mechanical injection equipment so Rudolf Diesel again began using air blast to provide atomization of the fuel as well as turbulence of the mixture. This was very successful and utilized in Rudolf Diesel's third engine built in 1895. This engine was very similar to engines being used today. It was a four-stroke cycle with 450psi compression. Progress in diesel engine development has since depended on improvements in fuel injection technology.

In 1922 Robert Bosch began the development of a fuel injection system for the diesel engine. By 1927 they finally had an acceptable injection pump. The demand for this pump was so great that Bosch in Germany was unable to keep up. In 1931 agreements were made with companies in France and England to produce injection pumps. In 1934 a company in the U.S. began manufacturing under the name of American Bosch and in 1938 the Diesel Kiki company in Japan was founded. Since then licenses have been granted to numerous manufacturing companies in several countries, most of which us Robert Bosch's designs to build injection pumps.

Rudolph Christian Carl Diesel

Born March 18, 1858, Paris
Died September 29, 1913, in the "English Channel"

No other engine inventor's name is as closely tied to his engine as Rudolph Diesel's is. But Diesel worked hard to make it that way. Historian Linwood Bryant tells us that Diesel saw himself as a scientific genius and the James Watt of the late 19th century.

Diesel started his education in Paris and spent most of his time in the museum of arts and crafts. The outbreak of the Franco-Prussian War forced him to leave Paris and go to London. He later studied in Munich under the German chemist Carl Von Linde. He invented the refrigeration system used now in many electrical refrigerators. Diesel grew to become a very important engineer and inventor.

He attempted to find better ways to use steam as the working fluid in heat engines. His patents in 1892 and 1893 were not for the engine but for the cycle of an engine employing the compression-ignition technique. In this cycle there were four phases. He did not have one fully rolling until 1897. Diesel attacked the problem of the compression-ignition engine not as a new concept but as a refinement of the petrol engine inventd by Nikolaus Otto in 1876. He spent the rest of his life introducing his invention to the world. He had many problems with manufacturing, licensing and financial stability. On Sept. 29, 1913, Diesel vanished off the Harwich-Antwerp ferry crossing the channel to England and his body was never found. Since his death the diesel engine has been very helpful in manufacturing and transportation.

He originally designed the diesel engine to run on peanut oil. Only later did petroleum become the standard. In a 1912 speech, Diesel said “the use of vegetable oils for engine fuels may seem insignificant today, but such oils may become, in the course of time, as important as petroleum and the coal tar products of the present time.”

history of methanol.
History
In their embalming process, the ancient Egyptians used a mixture of substances, including methanol, which they obtained from the pyrolysis of wood. Pure methanol, however, was first isolated in 1661 by Robert Boyle, who called it spirit of box, because he produced it via the distillation of boxwood. It later became known as pyroxylic spirit. In 1834, the French chemists Jean-Baptiste Dumas and Eugene Peligot determined its elemental composition. They also introduced the word methylene to organic chemistry, forming it from the Greek words methu, meaning "wine," and hyle, meaning "wood". The term methyl was derived in about 1840 by back-formation from methylene, and was then applied to describe methyl alcohol. This was shortened to methanol in 1892 by the International Conference on Chemical Nomenclature.

FRom snow preformance industries on the history of water methanol injection

In diesels, the effect is three fold: 1. The intercooling effect provides for more available air and all the benefits of a higher positive pressure ratio (more power giving fuel can be utilized safely without high combustion temperatures). 2. The combustion of water provides for more power on the power stroke. 3. Methanol acts as an additional fuel for more power.

A brief History:
Water injection was evaluated scientifically in the 1930’s by H. Ricardo who demonstrated that one can basically double the power output of an engine using water/methanol. The first widespread use was during WWII on supercharged and turbocharged aircraft. In 1942, the German Luftwaffe increased the horsepower of the Focke-Wulf 190D-9 fighter aircraft from 1776HP to 2240HP using 50/50% water/methanol injection. The allies soon followed by fitting the P51 Mustang and other high performance aircraft with water/methanol injection. Following the war, the turboprop aircraft industry used water/methanol injection and called it the “automatic power reserve system (APR)” for use in hot or high altitude take off. It surfaced again in the 60’s when GM used a system on the OEM turbo Corvair. It was used effectively in Formula 1 before being banned for adding too much power.

The latest competitive use is in World Rally Racing (WRC) where virtually all teams use it in some form and in diesel truck/tractor pulling competition. It is important to note that in the fall of 2004, the long standing world record in the quarter mile for diesels was broken twice (now 7.98 sec) by two different vehicles; both using the Boost Cooler® water/methanol injection system by Snow Performance
