Abstract
An exhaust system for a motor vehicle with a diesel engine (10) includes a particulate filter unit (36), a particulate receiving accumulator (24) close to the engine being arranged upstream of the particulate filter unit (36) and binding a partial quantity of the particulates contained in the exhaust gas flow, with another partial quantity of the particulates contained in the exhaust gas flow flowing through the particulate receiving accumulator (24) to the particulate filter unit (36). The particulate receiving accumulator (24) is arranged so close to the engine (10) that it is at least partly regenerated during operation owing to the NO2 oxidation effect.
