Description	This paper presents stability analysis of the reaction network corresponding to the mechanism of simultaneous oxidation of carbon monoxide CO, unburned hydrocarbons represented by acetylene C2O2 and reduction of nitrogen oxides NOx , taking place in the three-way catalytic converter used in cars to remove noxious components from exhaust gases. We use stoichiometric network analysis as a methodology for decomposing the entire mechanism into irreducible subnetworks (extreme currents) and examining stability of corresponding steady states. This methods allows for indication of those subnetworks, which may within a range of kinetic parameters display instabilities leading to oscillations. Within those subnetworks the major positive and negative feedbacks are used to explain the oscillatory dynamics in chemical terms, i.e., the role of chemical species and classification of the oscillatory modes are proposed.
