Abstract

Un motor de combustión interna que incluye una pluralidad de cilindros y un colector de admisión conectado para suministrar aire a dichos cilindros, un colector de escape conectado para recibir los gases de escape de los cilindros, caracterizado porque dicho colector de escape está dividido en secciones primera y segunda, estando conectada dicha primera sección para recibir los gases de escape desde un grupo de cilindros de bombeo de EGR y estando conectada dicha segunda sección para recibir los gases de escape desde el grupo restante de cilindros, una tubería de EGR conectada para conducir los gases de escape desde dicha primera sección de colector de escape a dicho colector de admisión, una unidad de turbina- compresor que incluye un compresor conectado para suministrar aire a dicho colector de admisión y una turbina dividida en secciones primera y segunda, estando conectada dicha primera sección de la turbina para recibir los gases de escape desde dicha primera sección del colector de escape y estando conectada dicha segunda sección de la turbina para recibir los gases de escape desde dicha segunda sección del colector de escape, y dicha primera sección de turbina tiene un área de flujo que aumenta la presión en dicha primera sección del colector hasta por encima de la presión en dicho colector de admisión.
