WebDual combustion cycle is an ideal and closed cycle. This consists of two isentropic processes, two constant volume processes and one constant pressure process. This cycle is adopted for Diesel ... 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 … See more The image shows a p-V diagram for the ideal Diesel cycle; where $${\displaystyle p}$$ is pressure and V the volume or $${\displaystyle v}$$ the specific volume if the process is placed on a unit mass basis.
