Formula for otto cycle ang carnot engine

[tomoyo_13m]

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?

tanx for your help

formula for otto cycle and carnot engine
otto cycle thermal efficiency = 1- 1/ r^(gamma-1) where r = compression ratio =Cp/Cv
heat added= Cv(T3-T2) kj/Kg
Heat rejected =Cv(T4-T1)KJ/Kg
m e p= Cv[(T3-T2)]-(T4-T1)]/(V1-V2)
Carnot engine thermal efficienc= workdone/heat added = (R ln V3/V2)[Th-Tl]/R Th lnV3/V2
w= [R ln v3/v2][Th-Tl] where Th = highest temp Tl = lowest temp.
efficiency=( TH-TL)/TH
