摘要： A fuel injection valve with a valve member axially displaceable in a bore of a valve body comprises a valve stem, the combustion chamber end, with which it interacts with a valve face of the valve body, at least one injection opening downstream of the valve face and opening into the combustion chamber to be supplied with fuel, a guide section of the valve body guiding the valve member and being disposed axially between an annular gap connected to the high-pressure fuel line and an annular space leading to the valve face, a first throttle connection permanently interlinking the annular gap and the annular space, and a second throttle connection interlinking the annular gap and the annular space as of a defined opening stroke of the valve member and having a smaller throttle resistance than the first throttle connection. The guide section is configured by a guide sleeve that is fastened at the combustion chamber end of the valve body in the bore so as to be stationary.

摘要： A common rail fuel system essentially comprising at least one rail, at least two injectors, and a respective supply line of a definite length between the rail and each injector. In order to prevent oscillation-generated movements of one supply line from being transmitted to the adjacent supply lines, the respective adjacent supply lines are embodied with different natural frequencies as a result of the supply lines of a rail being of different dimensions, for example different lengths.
