Abstract

"VEìCULO TRACIONADO A MOTOR COM CONTROLE DE EMISSãO DE EXAUSTãO".A presente inverção se refere a um método e uma disposição para manutenção da oxidação de No para C~2~ em um conversor catalítico de oxidação(5,25,35) disposto em um veículo compreendedo um motor de combustão interna (1,21,31)que em operação emite gases de exaustão para um sistema de pós-tratamento de gás de exaustão(2,22,32)compreendedo o referido conversor catalítico de oxidação(5,25,32)uma quantidade pré-determinada de hidrocarboneto sendo entregue para o sistema de pós-tratamento de gás de exaustão(2,22,32)ou para o motor ao longo de pelo menos um intervalo de tempo pré-determinado, para o próposito de manutenção da temperatura de trabalho ou regenerando uma unidade de trabalho de gás de exaustão(6,26,36,4,24,34).Em concordância com a presente inverção,o referido veículo compreendedo um motor de combustão interna está "caracterizado pelo fato"de que a referida quantidade de hidrocarboneto é entregue para o sistema de pós-tratamento de gás de exaustão (2,22,32)ou para o motor através de uma injeção com menos uma freqüencia de fragmentação pré-determinada e um período de injeção de maneira a abrangentemente manter uma produção de C~2~ no sistema de pós-tratamento de gás de exaustão(2,22,32)que prevaleceu imediatamente precedentemente para o referido intervalo de tempo para a injeção hidrocarboneto.
