Device for injecting fuel into the combustion chamber of an internal combustion engine

摘要

A device for injecting fuel into the combustion chamber of an internal combustion engine with at least one injector includes an injector body equipped with a high-pressure accumulator, a nozzle needle axially displaceably guided in the injector and surrounded by a nozzle chamber, a high-pressure line connecting the high-pressure accumulator to the nozzle chamber, and a resonator line arranged in parallel with the high-pressure line and communicating with the nozzle chamber and opening into the high-pressure accumulator via a resonator throttle. The resonator line and the high-pressure line, at least in their sections adjacent the high-pressure accumulator, are formed in a retaining body which, on its end face, is screwed into the accumulator pipe forming the high-pressure accumulator.

1. A device for injecting fuel into the combustion chamber of an internal combustion engine with at least one injector comprising
an injector body equipped with a high-pressure accumulator, a nozzle chamber; a nozzle needle axially displaceably guided in the injector and surrounded by the nozzle chamber, a high-pressure line connecting the high-pressure accumulator to the nozzle chamber, a resonator throttle; and a resonator line arranged in parallel with the high-pressure line and communicating with the nozzle chamber and opening into the high-pressure accumulator via the resonator throttle, wherein the resonator line and the high-pressure line, at least in their sections adjacent the high-pressure accumulator, are formed in a retaining body which, on its end face, is screwed into an accumulator pipe forming the high-pressure accumulator, and wherein the retaining body, on its end face screwed into the accumulator pipe, comprises an annular recess surrounding the mouth of the resonator line and the mouth of the high-pressure line.
