摘要:
A high-pressure fuel injection system includes a nozzle housing and a nozzle needle that is axially displaceable in the nozzle housing and with which an outflow opening in a valve seat of the fuel injection nozzle can be closed and opened. At least one pulsation reducer is arranged between the nozzle needle and an inside of the nozzle housing. The pulsation reducer includes a plurality of breakwater elements that dampen pressure pulsations in the fuel flowing through the injection nozzle to the outflow opening.
