how the carnot engine works&its efficiency? could you please clear this doubts sir/madam. thank you.

carnot engine have a reversible process containing four different processes... it’s efficiency is independent of temperature... still there is a lot to learn about carnot engine u can refer to a special book

@ chandu 

a carnot heat engine is a hypothetical heat engine which works on the besis of reversible carnot cycle . 
it is assumed as the most efficient heat cycle and it consists of two isothermal and two adiabatic process . 
the carnot engine works on the besis of carnot cycle , the following are the four phases of the cycle3 . 
1- reversible isothermal expansion of the gas at high temp. 
2- reversible adiabatic expansion of gas 
3- reverssible isothermal compression of gas at the lower temperature . 
4- reversible adiabatic compression of gas . 
HOPE IT CLEARS YOUR DOUBT 
ALL THE BEST ..
