摘要： A fuel injector apparatus comprising a piezoelectric driving stack and injector assembly wherein a flow control member of the fuel injector apparatus is driven directly by the piezoelectric stack without additional amplification means or interposing elements while the flow area of the nozzle portion is variably adjustable to deliver controlled flow rates in a desired flow profile to improve engine performance and reduce emissions. The injector configuration is adapted to support required flow rates with minimal linear movement of the flow control member.

摘要： A mechanically actuated electronically controlled unit injector includes an electronically controlled spill valve to precisely control timing of fuel pressurization within a fuel pressurization chamber. Cavitation bubbles may be generated in the region of the valve seat when the spill valve member is closed to raise fuel pressure in the fuel injector. This cavitation can cause erosion on the spill valve member and the surrounding injector body. In order to preempt cavitation damage, the valve member may be modified to include a compound annulus that includes a small annulus that corresponds to an identified cavitation damage pattern. Although the generation of cavitation bubbles may continue after such a strategy, cavitation erosion, and the associated liberation of metallic particles into the fuel system can be reduced, and maybe eliminated, by the preemptive cavitation reduction strategy.
摘要翻译：机械致动的电子控制单元喷射器包括电子控制的溢流阀，以精确地控制燃料加压室内的燃料加压的时间。当泄漏阀构件关闭以在燃料喷射器中提高燃料压力时，可能在阀座的区域中产生气蚀气泡。这种气蚀可能导致溢流阀构件和周围注射器主体的侵蚀。为了预防气蚀损伤，阀构件可以被修改为包括复合环，其包括对应于所识别的空化损伤模式的小环。虽然在这样的策略之后产生气蚀气泡可能会持续，但可以通过先发制人的空化减少策略来减少气蚀侵蚀和相关的金属颗粒向燃料系统的释放。

摘要： A fuel-injection system for injecting fuel into an internal combustion engine, having at least one fuel injector and a fuel-distributor line, is provided for each fuel injector with a connecting piece, which is connectable to an inflow section of the fuel injector. The connecting piece is connectable to the fuel injector via a screw connection made up of a screw cap and a thread. A retaining sleeve is able to be slipped with form locking over the screw cap and a counter-hold section, matched in form, on the side of the thread, in order to prevent a twisting of the screw cap and the thread relative to one another.

摘要： A fuel injection valve having a valve body (3), in which a bore (7) with a pistonlike valve member (10) disposed in it is embodied, which valve member (10) is longitudinally displaceably in the bore (7) counter to a closing force and by its longitudinal motion controls at least one injection opening (22), through which fuel can be injected into the combustion chamber of the engine. A valve holding body (1) is braced axially against the valve body (3). An inlet conduit (12), which carries fuel at high pressure, extends through the valve holding body (1) and its contact face, embodied as a high-pressure sealing face (30), on the valve body (3) as far as the injection openings (22). The bracing of the valve holding body (1) against the valve body (3) is effected by means of a lock nut (5), which grips the valve body (3) and with a female thread (44) engages a male thread (42) embodied on the valve holding body (1). The contact flank (52) of the male thread (42) and the contact flank (50) of the female thread (44), which are pressed against one another by the bracing, are embodied perpendicular to the longitudinal axis (8) of the male thread (42), so that upon the bracing of the lock nut (5), no radial forces oriented outward against the lock nut (5) result (FIG. 1).
