Diesel Cycle

Diesel Cycle Points : Diesel Cycle, Definition Diesel cycle was devised by Dr. Rudolph Diesel in 1893, with an idea to attain a higher thermal efficiency, with a high compression ratio. This is an important cycle on which all the diesel engine work. It is also known as constant pressure cycle as heat is supplied at a constant pressure. The engine imagined by Diesel has air enclosed i cylinder, whose walls are perfectly non-conductor of heat, but bottom is perfect conductor of heat. Again, there a hot body &.cold body and an insulating cap, which are alternately bought in contact with the cylinder. The ideal diesel cycle consists of two adiabatic, a constant pressure and a constant volume processes. These processes are represented on P—V diagram.
Let the engine cylinder contain “m” Kg of air at point 1. At this point it P₁ and T₁ and V₁ be the pressure, temperature and volume of the air.
