internal combustion engine with quality rotational frequency governing, internal mixture formation, lean air-fuel-ratio, diffusion flame and compression ignition

AI overview

A diesel engine is an internal combustion engine that ignites fuel through compression rather than spark plugs, operating with a lean air-fuel ratio and a diffusion flame. It matters because this design allows for efficient fuel combustion with quality rotational frequency control and internal mixture formation, making it a practical power source for vehicles and machinery.

Encyclopedic overview

1952 Shell Oil film showing the development of the diesel engine from 1877

A diesel engine is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is also called a compression-ignition engine (or CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). The diesel engine is named after its inventor, German engineer Rudolf Diesel.
