Abstract

"VEìCULO A MOTOR COM PURIFICAçãO DE DESCARGA". A invenção refere-se a um método de limpeza de um filtro durante operação de um veículo, compreendendo um motor de combustão interna (10), que durante operação envia descarga para um sistema de descarga (140) compreendendo o referido filtro, e uma transmissão (90) acionável pelo motor. O método é caracterizado pela etapa de selecionar uma relação de engrenagem na transmissão de veículo de modo que uma primeira temperatura compreendida em um primeiro intervalo de temperatura é obtida, o referido primeiro intervalo dependendo de um grau de entupimento do filtro com relação a um primeiro tipo de partícula. O método é adicionalmente caracterizado pela etapa de selecionar então uma relação de engrenagem de modo que uma segunda temperatura compreendida em um segundo intervalo de temperatura é obtida, o referido segundo intervalo de temperatura dependendo de outro grau de entupimento do filtro com relação a um segundo tipo de partícula. O primeiro tipo de partícula e o segundo tipo de partícula são diferentes entre si. As referidas seleções obtêm regeneração do filtro.
