摘要： A fuel injector with a direct needle control for an internal combustion engine, having an actuator, a hydraulic booster, and a nozzle needle guided in a nozzle body and acting on a nozzle needle sealing seat. The hydraulic booster includes a booster piston connected to the actuator and a nozzle needle booster piston connected to the nozzle needle; a booster chamber in the form of an actuator coupler chamber is associated with a pressure surface of the actuator booster piston; and depending on the pressure in the actuator coupler chamber, the nozzle needle is lifted away from the nozzle needle sealing seat, thus initiating an injection. In addition to the actuator booster piston, a control element is provided that is able to execute a stroke motion, is hydraulically coupled to the actuator coupler chamber by means of a first control surface, and is associated with a control chamber by means of a second control surface. The actuator booster piston has a second pressure surface, which, as an additional control surface, is associated with the control chamber.

摘要： A fuel injector for an internal combustion engine is proposed having a directly actuatable injection valve element. The fuel injector has a nozzle needle, axially guided in a nozzle body, and an actuator accommodated in an injector housing. The nozzle needle is connected to a coupling piston on the nozzle-needle side and the actuator is connected to a coupling piston on the actuator side. The coupling piston on the actuator side acts on a coupling chamber and the coupling piston on the nozzle-needle side acts on a control chamber. The nozzle needle is lifted from a nozzle-needle sealing seat as a function of the pressure in the control space. An intermediate plate is provided between injector housing and nozzle body. The plate has a conduit hydraulically connecting the coupling chamber to the control chamber. The conduit contains a hydraulic throttle which has at least two sections having different cross sections of flow. The section having the smaller cross section of flow faces the coupling chamber and the section having the larger cross section of flow faces the control chamber. The throttle disclosed suppresses oscillations of the actuator in the transmission of the actuator stroke to the nozzle needle stroke.

摘要： In a method for operating a fuel injection system for an internal combustion engine of a motor vehicle, an output signal of a pressure sensor which characterizes a fuel pressure in a pressure accumulator is evaluated. An undesirably high fuel pressure in the pressure accumulator and/or a fault in the fuel injection system is/are inferred at the time when the output signal assumes a maximally possible value for at least a predefinable monitoring period.
