Diesel Engine: How A 4 Stroke Diesel Engine OR Compression Ignition Cycle Works?

Diesel Engine Principle and Working Cycle Explained:

Basically, there are two types of diesel engine types – the Four Stroke and Two Stroke. The ‘Diesel Cycle’ uses higher Compression-Ratio. It was named after German engineer Rudolph Diesel, who invented and developed first Four-Stroke diesel engine. The four strokes of the diesel cycle are similar to that of a petrol engine. However, the ‘Diesel Cycle’ considerably defers by the way the fuel system supplies the diesel the engine and ignites it.

A conventional internal combustion diesel engine works on ‘Diesel Cycle’. In the simple diesel engines, an injector injects diesel into the combustion chamber above the piston directly. The ‘Compression-Ignition engine’ is also another name for the Diesel engine. This is mainly because it burns the diesel with hot and compressed air. The temperature of the air inside the combustion chamber rises to above 400°c to 800°c. This, in turn, ignites the diesel injected into the combustion chamber. Thus, the ‘Diesel Cycle’ does not use an external mechanism such as a spark-plug to ignite the air-fuel mixture.
