Abstract

Un sistema de recirculación de gas de descarga para reducir emisiones que incluye una porción de descarga que tiene un alojamiento de salida para recoger gas de descarga de un distribuidor de descarga de un motor de combustión interna. El sistema también incluye una porción de admisión que tiene un alojamiento de entrada para introducir aire hacia un distribuidor de admisión de un motor. El sistema también incluye un conducto de fluido para transportar gases de descarga desde la porción de descarga a la porción de admisión. El conducto incluye un primer extremo y un segundo extremo. El primer extremo está conectado al alojamiento de salida con una junta deslizante y el segundo extremo está conectado al alojamiento de entrada con una junta deslizante, sin la necesidad de ligazón intermedia. El sistema incluye una pluralidad de miembros de sello para sellar el sistema y permitir la expansión térmica. Los miembros de sello conectan el primer extremo al alojamiento de salida y conectan el segundo extremo al alojamiento de entrada.
