CONVERSOR CATALÍTICO COM DISPOSITIVO DE MONTAGEM PARA UM SENSOR DE OXIGÊNIO PARA GÁS DE EXAUSTÃO QUENTE.

摘要

A catalytic converter having a housing holding upstream and downstream catalytic material carrying substrates or bricks includes a ring located between the substrates, the ring having a gap therein for receipt of a mid-bed oxygen sensor. The ring traps a layer of insulating material between the ring and the converter housing or shell surface surrounding the inter-substrate gap. The ring is coupled to the housing at a plurality of embossments either by welding or mechanical couplings.
