    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.

    摘要： A method for operating a fuel injection system of an internal combustion engine is described. The fuel injection system has an injector for metering fuel into a combustion chamber of the internal combustion engine. The injector has an actuator, a control valve and a nozzle needle. In the method, the actuator is supplied a voltage and/or a current during an activation period. The control valve is set into a lifting motion by the actuator. The injector is opened and closed by the nozzle needle, using the lifting motion of the control valve. A further time period is ascertained. The further time period ends at the closing time of the nozzle needle. A function is ascertained, which links the activation period to the further time period. A shortest activation period, for which the nozzle needle opens and produces an injection, is ascertained with the aid of the function. An opening delay period (do1) of the nozzle needle is ascertained as a function of the shortest time period.

    摘要： An arrangement is proposed for forming a piezoelectric actuator, which has at least one piezoelectric element that in each case consists of a multi-layer structure of piezoelectric-layers, wherein internal electrodes arranged between the piezoelectric-layers in the direction of the build-up of the layers of the piezoelectric element, have an electrical voltage of different polarity alternately applied to them. Around the piezoelectric element, or in the case of multiple piezoelectric elements positioned in series in the activation direction, around the piezoelectric elements, and at least partially around the actuator head and the actuator foot there is arranged a covering system made from at least one layer of an insulating material. The at least one layer encloses the joints between the piezoelectric element or elements and the actuator head and the actuator foot, forming a seal.

    摘要： A fuel injection system for internal combustion engines, including a high-pressure part and a low-pressure part. In the high-pressure part, fuel is delivered to a high-pressure reservoir via a high-pressure pump and a high-pressure line. Injectors are supplied from the high-pressure reservoir. In the low-pressure part, the injectors communicate with a low-pressure reservoir where a pressure of ≦50 bar is maintained by a pressure holding valve. At a pressure in the low-pressure reservoir above the opening pressure of the pressure holding valve, the fuel is returned to the fuel container via a return line. The low-pressure reservoir communicates with the high-pressure line of the high-pressure part via an overflow valve and an overflow line.
