    摘要： An exhaust system for an internal combustion engine, which system comprises a monolith substrate (10) coated with a catalyst, which monolith substrate comprising a plurality of substantially parallel channels, each channel having a length extending from an upstream end to a downstream end; and a first sensor disposed in a hole (16) defined in part by an external wall of the monolith substrate, wherein the monolith substrate comprises a portion (12) of the plurality of channels wherein the catalyst composition in at least a part of the length of channels extending from the upstream end has an increased activity for a reaction for which the catalyst composition is intended relative to catalyst composition in a remainder (14) of the monolith substrate, the arrangement being such that the sensor is contacted substantially only with exhaust gas that has first contacted the catalyst composition having an increased activity.
