History of Diesel Engine

Internal combustion engine principles first proposed by Sadi Carnot in the early 19th century. Dr.Rudolf Christian Karl Diesel applied Sadi Carnote's principle into a patented cycle, that has become known as "Diesel Cycle". His patented cycle operated when the heat generated during the compression of the air fuel charge caused ignition of the mixture, which then expanded at a constant pressure during the power stroke of the engine.

Dr. Diesel's first engine ran on coal dust and used a compression pressure of 1500 psi( about 103 bar) to increase its theoretical efficiency. Also there was no provisions for cooling.

Consequently, between the extreme pressure and lack of cooling, the engine exploded and almost killed its inventor. After recovering from his injuries, Dr. Diesel tried again using oil as fuel, adding a cooling water jacket around the cylinder, and lowering the compression ratio to about 550 psi(about 35 bar). This combination eventually proved successful. Production rights to the engine were sold to Adolphus Bush, who built the first diesel engine for commercial use. Further lot of inventions affected construction and increased efficiency of the engine. Still now researches are going on for better results and alternatives.

Great look at the history of the diesel engine.
