Abstract

MéTODO DE CONTROLE DE UM SISTEMA TIPO TRILHO COMUM PARA INJEçãO DE COMBUSTìVEL DIRETA EM UM MOTOR DE COMBUSTãO INTERNA. Um método de controle para um sistema de injeção de combustível direta (1) em um motor de combustão interna (2) provido com um número de cilindros (3); o método compreendendo os estágios de: suprir fluido pressurizado para um trilho comum (5) por meio de uma bomba de alta pressão (6); acionar ciclicamente um número de injetores (4) tendo uma agulha hidraulicamente atuada (21) para injetar combustível nos cilindros (3); estabelecer um nível de pressão de combustível desejado dentro do trilho comum (5); determinar um valor limite (ETmin) para os injetores (4), de modo que nenhum combustível é injetado por cada injetor (4) se ele é acionado por um intervalo de tempo mais curto do que o valor limite (ETmin); e reduzir a pressão de combustível atual dentro do trilho comum (5) pelo acionamento dos injetores (4) por um intervalo de tempo de acionamento (ETred) mais curto do que valor limite (ETmin). (Figura 1).
