DEVICE AND METHOD FOR THE THERMAL TREATMENT OF AN EXHAUST-GAS FLOW

摘要

A device for the treatment of an exhaust gas flow includes at least one inflow channel with a front region and a rear region and at least one return flow channel. A first coating is provided in the rear region of the at least one inflow channel. The coating assists an exothermal reaction of the exhaust gas flow. A device is formed in the front region of the inflow channel for the transfer of heat from a return flow channel. A method for operating a device for the treatment of an exhaust gas flow, a vehicle having the device and an operating method for an exhaust gas system of a vehicle having the device, are also provided.
