Abstract: The purpose of the present invention is to provide a high pressure fuel rail apparatus for an engine directly spraying gasoline and a method for manufacturing the same capable of reducing costs and weight by omitting the process of brazing with the high temperature by applying an AI extruded material with the high temperature as the material of a fuel rail instead of the prior SUS material and performing the high speed cutting after a main pipe and a fixing bracket extrude. The high pressure fuel rail apparatus for an engine directly spraying gasoline according to the present invention to achieve the purpose comprises: a main pipe making fuel to flow therein and having both end parts mounted with an inlet fitting and an end plug; and a fixing unit integrally formed in the main pipe and fixing the main pipe in the upper end of the engine by using a bolt, wherein the main pipe and the fixing part are made of an aluminum alloy material. The present invention can reduce the unit cost of material by applying an aluminum alloy rather than the prior SUS material, and reduce costs and make a vehicle lighter by integrally forming the fixing unit in the main pipe.
Abstract translation: 本发明的目的是提供一种用于直接喷射汽油的发动机的高压燃料轨道装置及其制造方法，其能够通过应用AI挤压材料省略高温钎焊的方法来降低成本和重量 高温作为燃料轨道的材料而不是现有的SUS材料，并且在主管和固定支架拉伸之后执行高速切削。 根据本发明的用于直接喷射汽油的发动机的高压燃油轨装置旨在实现目的包括：使燃料在其中流动并具有安装有入口配件和端塞的两个端部的主管; 以及固定单元，其一体地形成在主管中，并且通过使用螺栓将主管固定在发动机的上端，其中主管和固定部由铝合金材料制成。 本发明可以通过应用铝合金而不是现有的SUS材料来降低材料的单位成本，并且通过在主管中一体地形成定影单元来降低成本并使车辆变轻。
