Diesel cycle - Wikipedia
The Diesel cycle is a combustion process of a reciprocating internal combustion engine.In it, fuel is ignited by heat generated during the compression of air in the combustion chamber, into which fuel is then injected. This is in contrast to igniting the fuel-air mixture with a spark plug as in the Otto cycle (four-stroke/petrol) engine. Diesel engines are used in aircraft, …
