Abstract
resumo misturador de gás de escape de reversão de fluxo, trata-se de um dispositivo de mistura de gás de escape para misturar um gás de escape produzido por um motor com um fluido de tratamento de gás de escape de reagente que é dosado no gás de escape a partir de um módulo de dosagem. o dispositivo de mistura de gás de escape inclui um tubo de decomposição que tem uma primeira extremidade e uma segunda extremidade. a primeira extremidade do tubo de decomposição é configurada para receber o gás de escape e o fluido de tratamento de gás de escape de reagente. um dispositivo de reversão de fluxo é posicionado na segunda extremidade do tubo de decomposição. o dispositivo de reversão de fluxo inclui uma pluralidade de membros de deflexão que misturam o gás de escape e fluido de tratamento de gás de escape de reagente, e direcionam o gás de escape e fluido de tratamento de gás de escape de reagente em direções predeterminadas, em que o dispositivo de reversão de fluxo reverte uma direção de fluxo do gás de escape de volta para a primeira extremidade do tubo de decomposição.
