Abstract

MOTOR DE COMBUSTãO INTERNA COM SISTEMA DE INTRODUçãO DE GáS DE ESCAPE. é descrito um motor de combustão interna (1) com um sistema de gás de escape (2), no qual pode ser introduzido gás de escape do motor de combustão interna (1) e dentro do qual está prevista uma unidade de transferência de calor (4), através da qual pode ser retirado calor do sistema de gás de escape (2) e que é colocado em uma câmara de processo (5) de um sistema de tratamento posterior de gás de escape (14) . Neste caso, a partir de um reservatório (8) pode ser retirado uma aditivo, que é colocado dentro da câmara de processo (5), no qual pode ser feita uma alteração de estado de agregado pelo menos parcial, por meio do calor retirado do sistema de gás de escape (2), e o aditivo pode ser adicionado ao sistema de gás de escape (2) com auxílio de uma unidade dosadora (16) conectada a jusante da câmara de processo (5) no sistema de tratamento posterior de gás de escape (14) A solução técnica descrita destaca-se pelo fato de a unidade de transferência de calor (4) estar alojada em um retorno de gás de escape (3) do sistema de gás de escape (2), no qual pode ser introduzido gás de escape do motor de combustão interna (1) e através da qual pelo menos uma parte do gás de escape pode ser conduzida a um suprimento de ar de combustão (21) do motor de combustão interna (1)
