In order to analyze an internal combustion engine, consider an ideal gas with constant specific heats (Cv = 4.18 J / g ∙ K) that performs a thermodynamic cycle, with adiabatic compression from V1 to V2, with the addition of heat at constant volume from state 2 to state 3, an adiabatic expansion from V3 = V2 to V4 = V1 and a constant volume cooling until reaching the original state. Check the Clausius inequality and conclude what type of process it is, considering that T3T1 = T2T4.
