Abstract

"SISTEMA DE INJEçãO DE COMBUSTìVEL PARA UM MOTOR DE COMBUSTãO INTERNA". A presente invenção refere-se a um sistema de injeção de combustível para um motor de combustão interna capaz de fornecer, em estrutura na qual válvulas de injeção de combustível são arranjadas sobre o lado a montante e sobre o lado a jusante da válvula de estrangulamento respectivamente, uma quantidade adequada de combustível para o interior da câmara de combustão todo o tempo, sem que combustível adira à, e permaneça na, válvula de estrangulamento, mesmo quando a válvula de estrangulamento é fechada de maneira abrupta. Com base em diversos parâmetros que incluem a abertura de estrangulamento (<sym>TH) e a velocidade de motor (NE), estão incluídos: dispositivos (101), (102), (105) para determinar cada quantidade de injeção das válvulas de injeção de combustível a montante e a jusante, dispositivo (5) para detectar uma taxa de mudança (<30><sym>TH) da abertura de estrangulamento na direção de fechamento da válvula de injeção, dispositivo (104a) para interromper injeção de combustível devido à válvula de injeção de combustível a montante quando a taxa de mudança (<30><sym>TH) é grande, e dispositivo (104b) para reduzir a quantidade de injeção a partir da válvula de injeção de combustível a jusante quando a injeção de combustível da válvula de injeção a montante é interrompida.
