Abstract

Patente de Invenção: "PROCESSO PARA O EMPREGO DE UMCATALISADOR-ACUMULADOR DE UM MOTOR DECOMBUSTãO INTERNA". é descrito um motor de combustãointerna, em particular, para um veículo automotor, que é provido deum catalisador-acumulador, que pode ser carregado edescarregado em óxidos nítricos. Por meio do aparelho de controleé possível determinar vários estágios de envelhecimento (pontos13) do catalisador-acumulador. Através do aparelho de controle,com base em vários, seguidos estágios de envelhecimento (pontos13) pode ser apurado um teor de enxofre existente no combustívelutilizado.
