The diesel engine has a long history that is intertwined closely with fiscal and other issues of the time. The diesel engine was made 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 go 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 accurate to efficient.
