摘要： A fuel delivery system includes a fuel pump assembly, an extension tube, and an injection nozzle assembly. The fuel pump assembly includes a pumping chamber, an inlet valve configured to direct fuel to the pumping chamber, a piston configured to pressurize fuel in the pumping chamber, an electromagnetic actuator operatively coupled to the piston, and an outlet check valve configured to direct pressurized fuel out of the pumping chamber. The electromagnetic actuator is configured to produce a force sufficient to move the piston to pressurize fuel in the pumping chamber and direct pressurized fuel through the outlet check valve. The extension tube is located downstream of the outlet check valve, and the injection nozzle assembly is located downstream of the extension tube. The injection nozzle assembly includes a nozzle check valve configured to selectively permit pressurized fuel received from the outlet check valve through the extension tube to exit the fuel delivery system.

摘要： A method refreshes an injection law of a fuel injector to be tested in an injection system. The method comprises steps of establishing a desired fuel quantity for the fuel injector to be tested, performing at least one first measurement opening of the fuel injector to be tested in a test actuation time, determining a pressure drop in a common rail during the first measurement opening of the fuel injector to be tested, determining a first fuel quantity that is fed during the first measurement opening, calculating a second fuel quantity as a difference between the desired fuel quantity and the first fuel quantity, and performing a second completion opening of the fuel injector to be tested for feeding the second fuel quantity needed to reach the desired fuel quantity.

摘要： A fuel rail assembly is disclosed. The fuel rail assembly includes an elongated tubular fuel rail and a plurality of fuel delivery lines for hydraulically coupling the fuel rail to fuel injectors. Each fuel delivery line has an injector cup, a pipe being arranged between the fuel rail and the injector cup, and a fixation bracket. A rigid connection is established between the fixation bracket and a portion of the pipe, the portion being spaced apart from each of the fuel rail and from the injector cup.The injector cup, the pipe, and the fixation bracket are individual parts. The fixation bracket is spaced apart from the injector cup and from the fuel rail.

摘要： In a GDI fuel rail mounting system comprising a fuel injection rail, having at least one fuel injector receiving cup with a generally cylindrical shape directly attached to the fuel rail generally perpendicular to and offset from the center of the fuel rail. The fuel rail further comprising at least one generally cylindrical attachment means proximal the fuel injector receiving cup, also attached to the fuel rail offset from the center thereof, the attachment means and the fuel injector receiving cup being disposed generally parallel to each other. A securing strap is attached to the outer curvature of at least one of the injector receiving cup and the attachment means, at least partially wrapping around the outer periphery of the attachment means, thereby inhibiting torsional, lineal, and lateral movement of the injector cup relative to the attachment means and the fuel rail.

摘要： A pressure relief valve for a common rail fuel system includes a hard ceramic spherical valve member that moves into and out of contact with a conical valve seat of a soft metallic valve body. Fretting damage to the valve is inhibited by using the dissimilar materials, and by using a guide pin that is allowed to move on the spherical surface of the ceramic spherical valve member. The valve member may be constructed of silicon nitride.
