Abstract
Patente de Invenção: "SISTEMA DE INJEçãO DE COMBUSTIVEL". Um sistema de injeção de combustível (1) para motores de combustão interna compreende uma válvula de injeção de combustível (12), que injeta combustível diretamente para dentro de uma câmara de combustão (2), formada por uma parede de cilindro (3), na qual é guiado um êmbolo (5), e uma vela de ignição (8) que se projeta para dentro da câmara de combustão (2). A válvula de injeção de combustível (12) gera na câmara de combustão (2) um jato de injeção (13) em forma de cone por meio de pelo menos uma fileira (23) de furos de injeção (24) dispostos na periferia num corpo de válvula (20) da válvula de injeção de combustível (12). Nisto, o corpo de válvula (20) possui adicionalmente um furo central de injeção (22) que gera uma área central do jato de injeção (13) direcionado para a vela de ignição (8).
