Abstract
Official abstract text for this publication.
In order to constitute a fuel high-pressure pipe that is compact and easy to connect to injectors, one of both the end sections of a fuel high-pressure pipe is formed as a first connecting section connected to a fuel supply port of one injector, and the other one of the end sections of the fuel high-pressure pipe is formed as a second connecting section connected to a fuel discharge port of another injector. The first connecting section and the second connecting section are linearly formed parallel to each other, and head sections of the first connecting section and the second connecting section, said head sections being on the connecting side to respective injectors, are formed in the directions opposite to each other.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel high-pressure pipe which forms a fuel supply passage between adjacent injectors, wherein one of end sections of the high-pressure pipe is a first connecting section connected to a fuel supply port of one of the injectors, and the other end section is a second connecting section connected to a fuel discharge port of the other injector, characterized in that the first connecting section and the second connecting section are formed straight and parallel to each other, and the fuel high-pressure pipe is disposed so as to be extended across a line connecting centers of the adjacent injectors in a plan view. 2. The fuel high-pressure pipe according to claim 1 , wherein a plurality of curving sections are provided between the first connecting section and the second connecting section. 3. The fuel high-pressure pipe according to claim 1 , wherein the fuel supply port and the fuel discharge port of each of the injectors are arranged opposite to each other, and wherein when the fuel supply ports of the plurality of injectors are directed to the same side, the first connecting section is connected to the fuel supply port of one of the injectors and the second connecting section is connected to the fuel discharge port of the other injector so that the fuel high-pressure pipe is connected between the one of the injectors and the other injector. 4. The fuel high-pressure pipe according to claim 2 , wherein the fuel supply port and the fuel discharge port of each of the injectors are arranged opposite to each other, and wherein when the fuel supply ports of the plurality of injectors are directed to the same side, the first connecting section is connected to the fuel supply port of one of the injectors and the second connecting section is connected to the fuel discharge port of the other injector so that the fuel high-pressure pipe is connected between the one of the injectors and the other injector.
