Abstract

"SISTEMA DE INJEçãO DE COMBUSTìVEL". A presente invenção se refere a um sistema de injeção de combustível para um motor de combustão interna, compreendendo um bocal (2) com uma entrada e um êmbolo (5) acionado por came formando uma câmara de êmbolo (7), a qual é conectada à entrada do bocal. O sistema de injeção compreende também um conduto comum (10) para o combustível e uma válvula de controle (9), instalada entre a câmara de êmbolo (7) e o conduto comum (10) , em que a válvula de controle é capaz de abrir ou fechar uma comunicação hidráulica entre a câmara de êmbolo e o conduto comum, após receber um comando de controle elétrico. Uma válvula de controle de bocal (21) atuada eletricamente é usada para abertura e fechamento do bocal (2). O sistema também compreende um dispositivo (11) para pressurização do conduto comum e regulagem da pressão do combustível no conduto comum (10).
