Abstract
"SISTEMA DE INJEçãO DE COMBUSTìVEL PARA MOTOR DE COMBUSTãO INTERNA". A presente invenção tem como objetivo prover um sistema de injeção de combustível para um motor de combustão interna, no qual válvulas de injeção de combustível são dispostas no lado a montante e no lado a jusante da válvula de estrangulamento, respectivamente, e em que a válvula de estrangulamento será impedida de congelar, sem o envolvimento da adição de uma tubulação e similar. A invenção refere-se, portanto, a um sistema de injeção de combustível para um motor de combustão interna, que tem uma válvula de injeção de combustível a montante provida a montante da válvula de estrangulamento e uma válvula de injeção de combustível a jusante provida a jusante dali, que inclui: um meio (101) para a determinação da quantidade de injeção total de cada válvula de injeção de combustível, um meio (102) para a determinação de uma taxa de quantidade de injeção de combustível devido a cada válvula de injeção de combustível; meios (2, 3) para a aquisição de uma informação de temperatura representando a temperatura da válvula de estrangulamento; e um meio (103) para a correção da taxa, com base na informação de temperatura, caracterizado pelo fato de o meio de correção (103) diminuir a taxa de injeção da válvula de injeção de combustível a montante, quando a válvula de estrangulamento estiver a uma temperatura baixa.
