摘要： A fuel delivery rail assembly for supplying fuel to a plurality of fuel injectors in an engine is provided. The assembly comprises an elongate conduit having a longitudinal fuel passage therein, a fuel inlet pipe, and a plurality of sockets. Outer walls of the conduit include at least one flat or arcuate flexible first absorbing surface, which is smoothly and integrally connected to an arcuate second absorbing surface. The first absorbing surface or the second absorbing surface faces fuel inlet ports of the sockets. The sectional configuration of the conduit can be flat, a telephone receiver shape, a character “T” shape, a corrugation shape, a dumbbell shape or a reverse eye mask shape. Thus, fuel pressure pulsations and shock waves are reduced by abrupt enlargements of fuel passages and bendings of the absorbing surfaces.

摘要翻译：提供了一种用于向发动机中的多个燃料喷射器供应燃料的燃料输送轨道组件。组件包括其中具有纵向燃料通道的细长导管，燃料入口管和多个插座。导管的外壁包括至少一个扁平的或弓形的柔性的第一吸收表面，其平滑且整体地连接到弓形的第二吸收表面。第一吸收表面或第二吸收表面面对插座的燃料入口。管道的截面形状可以是平坦的，电话接收器的形状，字符“T”形，波纹形状，哑铃形状或反向眼罩形状。因此，通过燃料通道的突然扩大和吸收表面的弯曲来减少燃料压力脉动和冲击波。

摘要： A purpose of the present invention is to provide a fuel delivery pipe having a flexible absorb wall surface formed on a wall surface thereof in which a fuel introduction pipe is connected to an interior of the fuel delivery pipe body at one end thereof in a longitudinal direction in order to achieve a suppression of a transfer of a first mode of a standing wave and a second mode of the standing wave and an enhanced placement layout and inexpensive cost.The fuel delivery pipe includes the flexible absorb wall surface formed on the wall surface thereof and injection nozzles, in which fuel introduction pipe 10 is connected to one end of fuel delivery pipe body 1 of a returnless type without a circuit returning to a fuel tank and is coupled with the fuel tank through an underfloor pipe arrangement. In the fuel delivery pipe, provided that an entire length of an interior of fuel delivery pipe body 1 in the longitudinal direction is 100, fuel introduction pipe 10 is inserted into fuel delivery pipe body 1 up to a position between 15 and 35 or a position between 65 and 85 with regard to the entire length and then securely connected to fuel delivery pipe body 1.
摘要翻译：本发明的目的是提供一种燃料输送管，其具有形成在其壁表面上的柔性吸收壁表面，其中燃料引入管在其一端沿纵向连接到燃料输送管体的内部以便实现驻波的第一模式和驻波的第二模式的抑制以及增强的布置布局和廉价的成本。燃料输送管包括形成在其壁表面上的柔性吸收壁表面和喷射喷嘴，其中燃料导入管10连接到无返回型燃料输送管体1的一端，而没有返回到燃料箱的回路，通过地板下的管道装置与燃料箱连接。在燃料输送管中，如果燃料输送管主体1的长度方向的整体长度为100，则将燃料导入管10插入燃料输送管主体1中，直到15〜35的位置，相对于整个长度在65和85之间，然后牢固地连接到燃料输送管体1。
