Consider a diesel cycle whose working substance is an ideal gas.
Defining the compression ratio r=Va/Vb and the shear ratio
rC=Vc/Vb, show that the efficiency is given by:
Consider A Diesel Cycle Whose Working Substance Is An Ideal Gas Defining The Compression Ratio R Va Vb And The Shear Ra 1 (2.7 KiB) Viewed 28 times
The PV diagram is shown in the figure below.
Consider A Diesel Cycle Whose Working Substance Is An Ideal Gas Defining The Compression Ratio R Va Vb And The Shear Ra 2 (21.75 KiB) Viewed 28 times
The process a→b is an adiabatic compression, b→c is an isobaric
expansion, c→d is an adiabatic expansion and d→a is an
isovolumetric process.
