HISTORY OF DIESEL ENGINE

In 1892, Rudolf Diesel, a German engineer, announced a new type of engine which fuel is injected into compressed air and ignited. This engine came to be known as the diesel engine.
By 1897, diesel engine that used heavy oil as fuel had been developed for practical use in Germany. (Low speed diesel engine)
Betwen 1924 and 1926, the development of the injection pump by Robert Bosch (from Germany) led to the development of high-speed diesel engines.
In Japan, research and development into diesel engines started around in 1930. By 1936, 6-cylinder air-cooled diesel engine with a total displacement of 8l had been developed and put to use.
In 1939, 5.1l-6-cylinder water-cooled automotive diesel engine began to be utilized, and diesel engine research and improvements have been continually pursued since then.



The history of diesel engines was briefly explained above. Research and development on diesel engines has been promoted in two separate areas; low-speed diesel engines for boats using heavy oil as fuel and high-speed diesel engine for automobiles such us Truck using light oil as fuel. In Japan research and develpoment on low-speed diesel engine has a longer history than hig-speed diesel engines. Low speed diesel engines have been used for boats and agricultural machinery and as power sources in industry.
