摘要： A fuel injector for fuel injection systems in internal combustion engines, including an actuator, a valve needle operable by the actuator for operating a valve-closure member, which, together with a valve-seat surface forms a sealing seat and a swirl device including at least one swirl channel, through which fuel flows with a tangential component relative to a longitudinal axis of the fuel injector. The axial position of a plunger element determines a cross-section of at least one bypass channel that bypasses the at least one swirl channel without a tangential component.

摘要： A method and system for placing logic nodes based on an estimated wiring congestion are provided. Specifically, under the present invention, relative probabilities for potential implementations of wiring interconnects between logic nodes are determined. Then, for each edge between adjacent bins, a total of corresponding relative probabilities is compared to a wiring availability. Based on the comparison, the logic nodes can be placed within wiring constraints.

摘要： A fuel injector is described, in particular an injector for fuel injection systems in internal combustion engines, that includes a valve needle having a valve-closure member which cooperates with a valve-seat surface arranged in valve-seat member to form a sealing seat and which has several injection orifices which are arranged downstream from the sealing seat, and are sealed by sealing seat against a fuel supply. A disk element is arranged downstream from the sealing seat, the disk element having at least one valve section, which changes its shape when the temperature changes. Valve section is connected to a heating element and optionally covers an injection orifice.

摘要： A method and a device for triggering an injector are described, allowing expansion of the metering range of the injector. The injector is triggered by a trigger voltage that is adjusted according to a predefined voltage for opening the injector, the trigger voltage being first increased to open the injector, starting from the predefined voltage, and then reduced after a predefined time. The predefined time is selected in such a way that the energy stored in an energy accumulator mechanism of the injector has reached a steady-state energy level after the predefined time.
