摘要： To obtain a gasoline direct injection rail that enables plating treatment to be easily and reliably performed on the inside of a rail body and an inlet part, also, that includes an orifice, and that has excellent mechanical properties. In a gasoline direct injection rail comprising a steel rail body 4, an inlet part 6 provided integrally with or separately from a first end 5 of the rail body 4 and comprising therein a communication passage 7 in communication with a fuel passage of the rail body 4, and a plurality of injector holders in communication with the fuel passage, a stainless orifice member 1 formed separately from the rail body 4 is securely disposed in the communication passage 7 of the inlet part 6.

摘要： Obtaining a fuel rail capable of forming a fuel rail body by hot forging and having high flexibility of the layout with a simple structure while reducing the cost even when the distance from the fuel rail body to the combustion chamber is long. A fuel rail body 1 and an injector cup adapter 6 independently formed from the fuel rail body 1 are included, the fuel rail body 1 is formed by hot forging, the injector cup adapter 6 is formed by cutting, and the injector cup adapter 6 and the fuel rail body 1 are connected and fixed to each other in a state that a connection portion 16 is sealed by an O-ring 15.

摘要： To provide a connection structure for a fuel pressure sensor that can prevents relative rotation between an abutting surface of a fuel rail and a sealing surface of a fuel pressure sensor, so as to suppress a deterioration in a sealing performance. A connection structure (1) for a fuel pressure sensor that connects a fuel pressure sensor (106) for detecting a pressure of a fuel to a fuel rail (103) in which the fuel to be supplied to an internal-combustion engine flows, includes a tubular attachment boss (10) that is formed in the fuel rail (103) and includes a male screw portion (13) and an abutting surface (14), an attachment portion (20) that is provided in a sensor body (106a) of the fuel pressure sensor (106), and includes a contact surface (22a) that abuts to the abutting surface (14) and a bearing surface (22b) provided behind the contact surface (22a), and a nut (30) including a female screw portion (33) that is screwed on the male screw portion (13) and a pressing portion (34) that presses the bearing surface (22b) to the abutting surface (14) by screwing the female screw portion (33) on the male screw portion (13).
