Fuel injector with hydraulically actuated pressure amplifier

摘要

Fuel injector for injecting fuel into combustion chamber (29) of internal combustion engine with minimum injector opening (28) with hydraulically operated nozzle needle (26) , pressure amplifier (5) and pressure amplifier piston (7) with high pressure piston part (10). Fuel pressure is intensified in high pressure intensifier body (6) and fuel under pressure comes out from high pressure area (23).
