摘要： In a fuel injection valve having a nozzle hole plate wherein a nozzle hole is formed, the nozzle hole is formed with a flow path cross-section having an oval shape that has long axes and short axes, and the nozzle hole is formed having a tapered shape in which a flow path sectional area becomes larger from an entry-side open end portion toward an exit-side open end portion. The nozzle hole is formed such that a second angle that is an intersecting angle of opposing nozzle hole inner wall surface portions in an oblique section along the short axes of the entry-side open end portion and the exit-side open end portion, is greater than a first angle that is an intersecting angle of opposing nozzle hole inner wall surface portions in a longitudinal section along the long axes of the entry-side open end portion and the exit-side open end portion.

摘要： PROBLEM TO BE SOLVED: To uniform sizes of fuel particles in spray in an early stage of fuel injection not to generate large droplets that are less likely to evaporate in the spray in the early stage of the fuel injection.
SOLUTION: A nozzle plate for a fuel injection device (3) is disposed opposed to a fuel injection port of a fuel injection device. A nozzle hole (6) through which fuel injected from the fuel injection port passes is formed at the nozzle plate (3). At this nozzle plate for the fuel injection device (3), the nozzle hole (6) has a fuel-flow-in-side opening end (6a) whose shape is a circular shape. The nozzle hole (6) is coupled to the fuel injection port via fuel guide channels (15 and 16). The fuel guide channels (15 and 16) have an opening (20) into the nozzle hole (6), and a pair of opposing channel sidewalls (21 and 22). The opening (20) has a channel width smaller than a hole diameter of the nozzle hole (6). One (21) of the opposing channel sidewalls (21 and 22) is formed to extend in a tangential direction of the nozzle hole (6). The fuel is directly flowed into the nozzle hole (6) to generate a flow of the fuel in a spiral pattern in the nozzle hole (6).
摘要翻译：要解决的问题：为了在燃料喷射的早期阶段使喷雾中的燃料颗粒的尺寸均匀，以在燃料喷射的早期阶段不产生在喷雾中不太可能蒸发的大液滴。本发明提供一种燃料喷射装置用喷嘴板（3），其与燃料喷射装置的燃料喷射口相对配置。在喷嘴板（3）上形成有从燃料喷射口喷射的燃料通过的喷嘴孔（6）。在该燃料喷射装置（3）的喷嘴板上，喷嘴孔（6）具有形状为圆形的燃料流入侧开口端（6a）。喷嘴孔（6）经由燃料引导通道（15和16）联接到燃料喷射口。燃料导向通道15和16具有进入喷嘴孔6的开口20以及一对相对的通道侧壁21和22。开口（20）的通道宽度小于喷嘴孔（6）的孔直径。相对的通道侧壁（21和22）中的一个（21）形成为沿喷嘴孔（6）的切线方向延伸。燃料直接流入喷嘴孔（6）以在喷嘴孔（6）中以螺旋形式产生燃料流。

摘要： The invention relates to a device for nebulizing or spraying or injecting liquid into an operating chamber, wherein at least one multiple jet nozzle (1) is provided, having at least two jet ducts (2, 3) for generating at least two liquid jets colliding at least partially with one another in a collision zone (7), such that a jet substantially in a fan shape can be produced, the extent of which in a fan plane is larger or at least twice as large as in the direction transverse to this fan plane, wherein a nozzle body (1) of the multiple jet nozzle (1) comprises at least the two jet ducts (2, 3), whereby a fan jet which is as stable and/or as controlled as possible is produced. This is achieved according to the invention in that a distance (A) of the nozzle body (1) from the collision zone (7) and/or a collision point (7) of the at least partially colliding liquid jets is between 0 millimetres (mm) and 15 times a diameter (D) of the jet duct/s (2, 3).

摘要： Combustion engines may emit soot. It may be necessary to eliminate soot from combustion engine emissions in order to comply with regulatory requirements. It may be desirable to avoid the need for a separate after treatment apparatus in order to eliminate soot from combustion engine emissions. A compression ignition engine is disclosed which may be configured to result in combustion having a peak value of equivalence ratio at the lift off length of less than 4.0. This may result in particulate emissions of fewer than 10
12 particles per kWh.

摘要： An injection valve for internal combustion engines is specified, which injection valve has a sealing seat, formed by a valve seat (14) and a closing head (15) of a valve needle (16), and a plurality of spray holes (21) which are arranged downstream of the sealing seat. The spray holes (21) of stepped cross section in each case have at least one upstream hole inlet section (22), with a very small hole cross section and a hole inlet opening (221), and a downstream outlet section (23) with a very large hole cross section and a hole outlet opening (231). In order to avoid undesired depositing of burnt fuel on the edges of the hole outlet openings (231), all hole outlet sections (23) are connected to one another via a groove (25) with a groove opening which points downstream.
