Abstract

Un dispositivo de control de EGR incluye una porción de cálculo de la proporción de EGR de estimación adaptada para calcular una proporción de EGR de estimación a partir de una cantidad de flujo de aire fresco en una porción de unión con el pasaje de EGR de un pasaje de admisión y una cantidad de gas de EGR que pasa a través de la válvula de EGR, y una porción de estimación de la proporción de EGR de la porción de unión adaptada para corregir una proporción de EGR de estimación con base en un estado gaseoso dentro del pasaje de introducción cuando la válvula de EGR conmuta de un estado cerrado a un estado abierto, para calcular una proporción de EGR de la porción de unión que es una proporción de una cantidad de gas de EGR con respecto al aire fresco en la porción de unión.
