Abstract

sistemas e métodos para montar um dosador em um componente de um sistema de pós-tratamento de gás de escape. a presente invenção se refere a um suporte de montagem de dosador para acoplar um dosador a um componente do sistema de pós-tratamento de gás de escape que tem uma parede lateral e uma abertura de componente do sistema de pós-tratamento de gás de escape que inclui uma superfície inferior, uma parede de engate, uma estrutura central, uma superfície superior e uma estrutura de fixação. a superfície inferior é configurada para ser mantida em uma posição oposta à parede lateral. a parede de engate se estende a partir da superfície inferior. a estrutura central tem uma abertura que se estende através da mesma e inclui uma estrutura de centralização que se estende a partir da superfície inferior e é configurada para ser recebida na abertura do componente do sistema de pós-tratamento de gás de escape. a estrutura de fixação se estende a partir da superfície superior e é configurada para ser acoplada ao dosador. a parede de engate é configurada para separar a superfície inferior da parede lateral quando a parede de engate faz interface com a parede lateral, de modo que um bolso seja formado entre a parede de engate, a estrutura de centralização e a superfície inferior.
