Abstract

MéTODO PARA ESTIMAR UMA CARGA DE AR EM PELO MENOS UM CILINDRO DE COMBUSTãO DE UM MOTOR DE COMBUSTãO INTERNA. Um método de estimar uma carga de ar em pelo menos um cilindro de combustão de um motor de combustão interna inclui calcular fluxo de ar em massa de cilindro baseado em um parâmetro de eficiência volumétrica modificado; e calcular o fluxo de ar em massa de estrangulador de admissão baseado em um parâmetro de descarga de fluxo de ar de estrangulador e um fator de enriquecimento do combustível. Três modelos incluindo um modelo de fluxo de cilindro de valor médio, um modelo de dinâmica de coletor, e um modelo de fluxo de estrangulador são providos para estimar a carga de ar no pelo menos um cilindro de combustão e controlar dispensação de combustível ao sistema de dispensação de combustível.
