Abstract

"INJETOR DE COMBUSTìVEL PARA UM MOTOR DE COMBUSTãO INTERNA". A presente invenção refere-se a um injetor de combustível compreendendo uma cabeça (13) tendo uma face externa livre (20) e um orifício principal, a qual é adaptada para injetar um jato de combustível a uma direção principal (P) e um segundo orifício (15) que é adaptado para injetar um jato de acordo com uma direção para uma superfície externa e se comunicam diretamente com uma câmara de injeção (24). A direção secundária forma um ângulo A de 100 - 800<198> com a direção principal de modo que o jato secundário (26) intercepta o jato principal (22) em uma zona de rompimento (30) que inicia em uma distância (d).
