Adiabatic compression of air in a cylinder of a diesel engine. Maximum Initial volume compression The compression ratio of a diesel engine is 15 to 1 as shown in the figure. How much work does the air in the cylinder do during the adiabatic compression if the initial volume is Vi=1.0x10³ m³, the initial pressure is pi=1.01x10° Pa and the initial temperature is T1=300 K? Hint: Air is mostly a mixture of diatomic molecules; treat it as an ideal gas with Cy=(5/2)R and C,=(7/2)R.
