Abstract

"SISTEMA DE INJEçãO DE COMBUSTìVEL". Um sistema de injeção de combustível (1) para motores de combustão interna com uma válvula de injeção de combustível (10), que apresenta um disco de furos de pulverização, pelo qual o combustível é injetado na câmara de combustão (2). A câmara de combustão (2) é limitada por uma parede de cilindro (3). Um êmbolo (6) é guiado na parede de cilindro (3), e uma vela de ignição (7) se projeta para dentro da câmara de combustão (2). Os diâmetros de furos de injeção dispostos no disco de furos de pulverização estão distribuídos de tal maneira que, num determinado momento da injeção, o combustível injetado é distribuído tão homogeneamente quanto possível em um volume de injeção (23) da câmara de combustão (2) limitado pelo êmbolo e pela parede de cilindro (3).
