Abstract

"CONJUNTO INJETOR DE COMBUSTìVEL QUE POSSUI REGULADOR DE PRESSãO DE INJEçãO INICIAL E INJEçãO DE PICO COMBINADO" Conjunto injetor de combustível para um motor de combustão interna, que inclui um corpo injetor em comunicação fluida com uma fonte de combustível e um conjunto de bocal, através do qual o combustível é disperso a partir do conjunto injetor de combustível durante um evento de injeção. Um sistema de fornecimento de combustível sob alta pressão fornece combustível sob alta pressão para o conjunto de bocal. Além disso, o conjunto injetor de combustível inclui um regulador de pressão de injeção inicial e injeção de pico combinado que é operável para controlar o conjunto de bocal, a fim de regular a velocidade de injeção de combustível no início de um evento de injeção, e é adicionalmente operável para limitar a pressão máxima do combustível disperso a partir do conjunto do bocal.
