Why should a Carnot cycle have two isothermal two adiabatic processes?

1.	Why should a Carnot cycle have two isothermal two adiabatic processes?
Answer» With two isothermal and two adiabatic processes, all reversible, the efficiency of the Carnot engine depends only on the temperatures of the hot and cold reservoirs. [Note : This is not so in the Otto cycle and Diesel cycle.]
