Abstract

"SISTEMA DE INJEçãO DE COMBUSTìVEL DO TIPO COMUM DE TRILHO COM BOMBA DE VELOCIDADE DE FLUXO VARIáVEL". Sistema de injeção de combustível (1) do tipo de trilho comum equipado com uma bomba de alta pressão (4), que fornece combustível para um canal comum (3) que, por sua vez, abastece uma série de injetores (2), e uma unidade de controle (7), que é capaz de manter a pressão do combustível no interior do canal comum (3), momento a momento, igual a um valor desejado que varia geralmente ao longo do tempo; a unidade de controle (7) é acoplada a um dispositivo (6) para regulagem da velocidade de fluxo da bomba de alta pressão (4), a fim de controlar a velocidade de fluxo da bomba de alta pressão (4), de forma a fornecer ao canal comum (3), momento a momento, a quantidade de combustível necessária a fim de ter o valor desejado de pressão no interior do mencionado canal comum (3).
