Abstract

Se proporcionan métodos y sistemas para mejorar el control de la alta dilución de EGR. Una cámara de admisión se divide para que se pueda suministrar aire puro y EGR a los cilindros del motor mediante porciones de cámaras destinadas. Se proporcionan distintos conjuntos de válvulas reguladoras en los puertos de admisión del cilindro acoplados a las diferentes porciones de cámara para que se pueda ajustar rápidamente una proporción de flujo de aire y flujo de EGR a los cilindros del motor en respuesta a cambios bruscos (por ejemplo, aumento o descenso) en la demanda de EGR.
