    摘要: A multipoint fuel injection system comprises an injection system segment including a circumferentially extending outer support defining a fuel manifold with a plurality of manifold passages extending circumferentially therethrough. A first connector is included at a first circumferential end of the outer support and a second connector is included at a second circumferential end of the outer support opposite the first circumferential end. The first and second connectors are each configured to connect each manifold passage with a manifold passages of a respective outer support of a circumferentially adjacent injection system segment. The system includes a circumferentially extending inner support and a plurality of circumferentially spaced apart feed arms extending radially between the inner support and the outer support. A plurality of outlet openings extend in an axial direction from each feed arm for feeding respective injection nozzles.

    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: 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.

    摘要: The present disclosure is directed to a fuel circuit of a fuel injector that includes a first channel, a second channel, and a valve. The first channel is configured to receive a first fuel and define a flow path for the first fuel. The second channel is configured to receive a second fuel and define a flow path for the second fuel. The valve is in fluid communication with the first channel and the second channel. The valve is adapted to direct the second fuel to the first channel when a pressure in the first channel reaches a predetermined level.
