Abstract

In this work we present for the first time a local stability analysis of an irreversible Otto cycle considering internal irreversibilities, through a parameter that comes from the Clausius inequality and in terms of the Otto cycle temperatures and also considering the ambient temperature and the temperature after combustion, where the small variations occurs. In our study, we use different regimes of performance: Maximum output power (MP), maximum efficiency (ME), maximum ecological function (MEF) and maximum efficient power (MEP). We apply the local stability theory to construct the characteristic functions and we obtain the relaxation times of the Otto cycle. It is show that the steady state of internal temperatures of the Otto cycle are asymptotically stable under any local perturbation.
