hi i just want to know the formula of the otto cycle for the folowwing parameter:
compression ratio,cycle work,heat added,heat rejection,thermal efficiency and mean effective pressure.

and also may i know the formula for getting the pressure (bar) and the volume(m3/kg) temperature(K) for carnot engine, the cycle efficiency, heat added and work cycle?

formula for otto cycle and carnot engine
otto cycle thermal efficiency = 1- 1/ r^(gamma-1) where r = compression ratio =Cp/Cv
