Particulate control
摘要:
An improved system for treating the aftertreatment of exhaust gases, especially from diesel engines, comprises a first catalyst (20) effective to oxidise hydrocarbons, a second catalyst (22) effective to convert NO to NO2, a trap (24) for particulates, on which particulates may combust with the NO2, and optionally a NOx absorption material (26).
