Fuel injector for injecting fuel in combustion chamber of internal combustion engine, has high pressure chamber which is attached to injector body, where high pressure chamber is communicated with nozzle chamber

摘要

The fuel injector has a high pressure chamber which is attached to an injector body (1), where the high pressure chamber is communicated with a nozzle chamber (6). The nozzle chamber is connected over nozzle holes (8) with the combustion chamber, where the nozzle holes are controlled by a nozzle needle (9). The high pressure chamber and the nozzle chamber are communicated with each other over a connection and a throttling channel in a parallel manner.
