Abstract
SISTEMA DE INJEçãO DE COMBUSTìVEL ADEQUADO PARA COMBUSTìVEIS DE BAIXA VISCOSIDADE. A presente invenção se refere a um sistema de combustão interna compreendendo um Sistema de Gerenciamento de Motor (Engine Mana gement Sys tem) (EMS) (6), uma bomba de alimentação de combustível (2), uma linha de retorno (13), uma bomba de alta pressão (3), suprindo combustível sob pressão para uma grade comum (4), uma válvula hídraulicamente operada (7) formando uma câmara de saída (9) conectada para a grade comum (4) e uma câmara de controle (10), a válvula (7) sendo projetada de maneira que, em sua posição fechada, a válvula previne o fluxo para fora da câmara de saida (9), e uma válvula piloto eletrícamente operada (12) adaptada para controlar a posição da válvula hidraulícamente operada (7). Em concordância com a presente invenção, o referido sistema de injeção de combustível para um sistema de combustão interna está caracterizado pelo fato de que um bocal (8) com um recurso resiliente (flexivel) (18) que inclina (guia) o bocal (8) em direção ao fechamento, é conectado para a saida da válvula hidraulicamente operada (7) de uma maneira tal que a pressão na saída da válvula hidraulicamente operada (7) tende a superar a força do recurso resiliente (18) e abre o bico (8), e de que uma válvula de derramamento eletricamente operada (19) é conectada entre a saída da válvula hidraulicamente operada (7) e a linha de retorno (13)
