Abstract
CÂMARA DE DECOMPOSIÇÃO. A invenção se refere a uma câmara de decomposição para um sistema de pós-tratamento de gás de escape, que inclui um tubo de entrada, um membro catalisador de redução catalítica seletiva (RCS), uma parede do coletor de mistura, uma tampa de distribuição e um tubo divisor. O tubo de entrada é configurado para receber o gás de escape. A parede do coletor de mistura inclui uma abertura do fluxo do conjunto de mistura. A tampa de distribuição é acoplada ao tubo de entrada e configurada para receber o gás de escape a partir do tubo de entrada. O tubo divisor é acoplado à parede do coletor de mistura. O tubo divisor separa a tampa de distribuição da abertura do fluxo do conjunto de mistura. O tubo divisor inclui uma primeira abertura de entrada do tubo divisor que é configurada para receber o gás de escape a partir da tampa de distribuição. A abertura de saída do tubo divisor é configurada para fornecer o gás de escape para a abertura do fluxo do conjunto de mistura.
