Abstract

resumo arranjo para inserir um meio líquido em gases de descarga a partir de um motor de combustão arranjo (1) para inserir um meio líquido em gases de descarga a partir de um motor de combustão, compreendendo: - uma câmara de misturação (2) destinada a ser borrifada pelos gases de descarga e delimitada em uma direção radial no sentido para fora por uma primeira parede de metal tubular (6), e - um elemento de injeção (10) para injeção do meio líquido como uma pulverização (11) na câmara de misturação (2), e - um canal de descarga (12) que se estende ao longo do exterior da primeira parede tubular. o canal de descarga (12) é delimitado em uma direção radial no sentido para fora por uma segunda parede tubular (13), a qual guia os gases de descarga fluindo através do canal de descarga de modo que eles passem sobre o lado externo da seção de parede (6a) da primeira parede tubular que deve ser impactada pela pulverização. um estrangulador (14) é disposto na seção (12a) do canal de descarga que está localizado no lado externo da seção de parede (6a) para acelerar os gases de descarga de modo que os mesmos fluam com uma velocidade aumentada sobre o exterior da seção de parede (6a).
