| description | A particulate filter is fluidly connected to and disposed downstream from a diesel engine exhaust stream outlet. The filter has a plurality of filter segments that have differing physical properties or structural characteristics such that the engine exhaust stream to fuel stream ratio is maintained substantially consistent among segments during their regeneration. A method for regenerating a segmented filter comprises maintaining the engine exhaust stream to fuel stream ratio substantially consistent among segments during their regeneration.
Le filtre selon l'invention est raccordé fluidiquement à une sortie de flux d'échappement d'un moteur diesel et disposé en aval de celle-ci. Le filtre présente une pluralité de segments de filtre qui ont des propriétés physiques ou des caractéristiques structurelles différentes de telle sorte que le rapport du flux d'échappement du moteur au flux de carburant soit maintenu sensiblement consistant parmi les segments pendant leur régénération. L'invention concerne aussi une méthode de régénération d'un filtre segmenté, ladite méthode comprenant le maintien du rapport du flux d'échappement du moteur au flux de carburant à un niveau sensiblement consistant parmi les segments pendant leur régénération. |
