    摘要: A method for treating engine emissions and a device for treating engine emissions and dampening engine noise are provided. The invention provides for multiple zones of reaction so as to treat reducible emission components by providing a low oxygen, relatively cool reducing zone and also to treat oxidizable emission components by providing a relatively high oxygen, hotter oxidizing zone. A feature of the invention includes a heating means situated adjacent to or embedded into an oxidizing catalyst or an oxidation zone of a three-way catalyst.
