Abstract

a presente invenção refere-se a um dispositivo para introduzir um fluido em uma corrente de gás, em particular um agente redutor em uma corrente de gás de escape de um motor de combustão interna. o dispositivo tem uma câmara de mistura e um dispositivo de medição por meio do qual o fluido pode ser introduzido, através de uma ponta dosadora, em um espaço de injeção definido por uma bucha protetora, cujo espaço de injeção está disposto dentro da câmara e está em conexão fluídica a este último. a bucha protetora tem uma câmara intermediária que se estende na direção circunferencial da bucha protetora e é limitada internamente de modo radial por uma parede interna e externamente de modo radial por uma parede externa, em que a câmara intermediária é conectada de forma fluídica ao espaço de injeção através de um vão, em particular, um vão anelar, formado por e na parede interna. a câmara intermediária também é conectada de maneira fluídica à câmara de mistura através de pelo menos uma abertura na parede externa.
