Abstract

dispositivo para purificar gás de exaustão de um motor de combustão interna para difundir de forma homogênea, no gás de exaustão, um aditivo que é fornecido para um dispositivo para purificar gás de exaustão de um motor de combustão interna. um dispositivo a montante para purificar gás de exaustão e um dispositivo a jusante para purificar gás de exaustão são conectados conjuntamente por meio de um cano de descarga tendo uma área seccional menor que aquela do dispositivo a montante para purificar gás de exaustão e menor que aquela do dispositivo a jusante para purificar gás de exaustão, uma parte de passagem de conexão é fornecida para conectar a saída de exaustão de um catalisador no dispositivo a montante para purificar gás de exaustão ao cano de descarga, a parte de passagem de conexão sendo assim formada em que o eixo geométrico central do dispositivo a montante para purificar gás de exaustão na direção na qual o gás de exaustão flui não é alinhado com o eixo geométrico central do cano de descarga na direção na qual o gás de exaustão flui, dispositivo de injeção é arranjado na parte de passagem de conexão para injetar o aditivo na passagem de exaustão de maneira que o aditivo chega à superfície de parede oposta da parte de passagem de conexão.
