What is Otto Cycle?
The cycle of a highly idealized gasoline engine can be approximated by the Otto cycle. 1 → 2 and 3 → 4 are adiabatic compression and expansion, respectively; 2→3 and4→1 are constant volume processes. Attend the working medium as an ideal gas with constant g≡Cp/Cv.
a) Compute the effectiveness of this cycle forg=1.4 and compression ratio r = Vi /Vf =10.
b) Compute the work done on the gas in the compression process1→2, assuming initial volume Vi = 2L and Pi =1 atm.
