Definitions
- the present invention relates to a fuel rail (delivery) for supplying high-pressure fuel supplied from a fuel pressurizing pump such as an electronic fuel injection type automobile engine via a fuel injector (injection nozzle) that directly injects the fuel into a cylinder of the engine. More particularly, the present invention relates to a terminal seal structure of a fuel rail for a gasoline direct injection engine having an injection pressure of about 20 to 100 MPa in a type in which fuel is directly supplied from a rail to an injector.
- a fuel rail for a gasoline direct injection engine of this type for example, in a fuel rail having a main pipe and a plurality of branch pipes, through holes for receiving the branch pipes are formed on the outer wall of the main pipe.
- the through hole has an annular wall projecting outward and inward of the main pipe, and each branch pipe is structured to be fixed to the annular wall, and the branch branch pipe is connected to the body portion which is a pressure accumulating vessel.
- fuel rails and the like that are configured to be connected directly or via a branch joint fitting (nipple), and a structure in which an injector connection socket is directly attached to a rail body made of a pipe or other tubular body.

- the above-described conventional fuel rail for a gasoline direct injection engine has the following problems. That is, in the conventional fuel rails for various gasoline direct-injection engines, the rail body formed of a pipe or the like has a structure in which one end or both ends are closed, and the terminal rail structure is, for example, FIG.

Abstract
Description
即ち、上記従来の各種のガソリン直噴エンジン用燃料レールにおいて、パイプ等の管体からなるレール本体は一端又は両端が閉じられた構造となっており、その端末レール構造は、例えば図2、図3に拡大して示すように、円筒状の本体パイプ111の開口端部にエンドキャップ112A、112Bを、それぞれろう付けにて接合する構造のものが一般的である。
さらに、ろう付け部113A、113Bが直接燃料(圧力媒体)に接することから、当該ろう付け部に形状の不均一部分が存在した場合には、応力集中による当該ろう付け部の破損の要因となり易いこと、等の問題がある。
本発明におけるガソリン直噴エンジン用燃料レールは、一端もしくは管壁面に燃料導入管(図示せず)が接続され、その燃料導入管は配管(図示せず)を介して燃料タンク(図示せず)に連結されており、この燃料タンクの燃料が配管及び燃料ポンプを介して燃料導入管に移送され、燃料導入管から本管レールへと流動し、インジェクター(図示せず)からシリンダー(図示せず)内に噴射される。
この本管レールは、ガソリン直噴エンジン用燃料レール本体であって、周壁部に前記インジェクターを接続可能とするソケット(図示せず)等が複数設けられている。例えば4気筒エンジンの場合には4個のソケットが、直列6気筒エンジンの場合には6個のソケットが、それぞれ所望の間隔で設けられている。
又、燃料レール本体1とカラー2とのろう付け部3は、ガスケット5の作用により燃料レール本体1内の燃料(圧力媒体)に接しない構造となっているので、該ろう付け部に形状の不均一部分が存在しても応力集中による破損の要因となることが皆無となるのみならず、凸形エンドキャップ4の締め付けにより発生する軸力により燃料レール本体1の開口端面(受圧面)1-1bにガスケット5を圧接させてシールするメタルシール方式であるから、燃料レール本体1端部のシールの安定性、信頼性も確保される。
