Abstract

APARELHO PARA MISTURAçãO DE UM MEIO LìQUIDO EM UM MEIO GASOSO. A presente invenção se refere a um aparelho para misturar meio líquido em um meio gasoso fluindo através de uma tubulação de exaustão (10) a partir de um motor decombustão interna, O meio líquido é suprido para a tubulação de exaustão (10) com fluxo de massa variado por intermédio de um bocal injetor (11) direcionado para a tubulação de exaustão (10). A tubulação de exaustão (10) possui um misturador (16) colocado à jusante do bocal injetor (11) e um caminho de fluxo (18) disposto paralelo com o misturador (16) e se estendendo através de uma superfície perfurada (19). Em concordância com a presente invenção, o referido aparelho está caracterizado pelo fato de que a superfície perfurada (19) é constituída por uma porção em parte perfurada (19) da parede (12) da tubulação de exaustão (10) e de que as perfurações (19) a montante do misturador (16) possuem uma área que está entre cerca de 0,5 vez - 3,0 vezes a área de seção transversal da tubulação de exaustão (10) e de que o misturador (16) é constituído por uma placa (16) inserida na tubulação de exaustão (10).
