Carnot cycle


Carnot cycle
A name given to the cycle of operations of an internal combustion engine that would take place in an ideally perfect engine in which friction is nonexistent and heat losses are totally absent. A theoretical cycle derived by Nicoles Leon-hard Sadi Carnot, who enunciated it in 1874. The four events that occur in a Carnot cycle are (i) an isothermal expansion, (ii) followed by an adiabatic expansion, (iii) an isothermal compression, and (iv) to an adiabatic compression. The cycle is depicted in the illustration.
