EXHAUST SYSTEM COMPRISING EXOTHERM-GENERATING CATALYST.

摘要

An apparatus comprising a compression ignition engine and an exhaust system thereforcomprising at least one exhaust system component for treating exhaust gas andmeans for generating an exotherm for heating the at least one exhaust system component,which exotherm generating means consisting essentially of a catalyst and meansfor inject ing hydrocarbon into exhaust gas for combustion on the catalyst, whichcatalyst consisting essentially of both a palladium (Pd) component and a platinum(Pt) component, and an optional support material, disposed on a substrate monolith.
