    摘要: The present invention relates to an exhaust system for a combustion engine, particularly of a vehicle, with an oxidation catalytic converter (oxicat), with an electrically heatable catalytic converter (E-cat) arranged upstream of the oxicat and with a fuel injector arranged upstream of the E-cat.An energetically favourable mode of operation is achieved when a particle filter is arranged downstream of the oxicat, when a bypass path bypassing the E-cat commences downstream of the fuel injector and ends upstream of the oxicat and when the E-cat is designed for a smaller exhaust gas flow rate than the oxicat.
