摘要： A fluid pulse damper having increased dynamic range and sensitivity, being especially useful in suppressing pulsations in the fuel supply rail of an internal combustion engine. The damper is a longitudinal gas-filled plastic pillow having walls formed by opposed flexible short sides and opposed flexible long sides, and includes at least one internal self-contact element, and preferably a plurality of such elements. As the short sides flex, the elements make contact internally, shifting the damper into a different compression regime and extending the pressure/response over an increased range of pressures. A feature of some embodiments is that the inner surface within the contact elements is shifted into tension after the elements make contact, thereby stiffening the damper and increasing the damper's resistance to further deformation. The damper is formed of a plastic such as ultra-high molecular weight polyethylenes, high flow polyetherimides, or tubing grade polyphthalamides.

摘要： An internal pulse damper for use in a fuel rail for an internal combustion engine. The damper is formed from a length of tubular metal stock having a flat oval cross-section and ends flattened by crimping to form a captive-air pillow. The end crimps are improved through use of tooling to eliminate a creased sidewall area vulnerable to stress failure in prior art pulse dampers. Such tooling includes constraints to prevent the tubing sides from flaring out and forming a longitudinal crease adjacent the end crimp during squeezing-shut of the tube end.

摘要： An internal pulse damper for a fuel rail. The damper has an increased captive air volume and consequent improved damping and stress characteristics. The improved damper is a pillow having a modified flat oval cross-sectional profile, with two long diaphragm sides and rigid short sides connecting the two long sides. At least one of the short sides, and preferably both, is strengthened by being provided with a longitudinal reverse bend or inwardly-extending longitudinal rib generally parallel with the long sides. Preferably, the short sides are somewhat higher than the comparable short sides of similar prior art dampers, to increase the captive air volume, yet are not high enough to preclude installation of the improved damper within an existing fuel rail configuration.

摘要： A fuel pressure regulator including a valve head having a centerline offset from the centerline of a corresponding fuel orifice. The valve head may be offset with respect to the valve seat and orifice, the orifice may be offset within the seat with respect to the head and diaphragm assembly, or the axes of the head and seat may be non-coaxially biased. Because the vector of the valve closing force does not align with the centerline of the valve head and diaphragm assembly, a resulting torque on the valve head keeps the head in a stable, pivoted position at all flow rates. The valve head always makes contact with the valve seat at a predetermined point during regulator operation, eliminating pressure instabilities and noise experienced in prior art pressure regulators.

摘要： An anti-rotation clip for joining a fuel injector body to a fuel rail socket. A C-shaped base is formed to slide into an annular groove in the injector body. A pair of tangs extend from the base to straddle a rib on the injector body to prevent rotation between the clip and the injector. Opposed sidewalls extending from the base include windows for receiving a radial flange of the fuel rail socket to correctly position the fuel injector axially within the socket. Each window is divided by a locking bar for reception in a notch in the socket flange to prevent rotation between the clip and the socket. The radial positions of the injector rib and flange notch are selected such that the injector will be properly oriented with respect to the engine after installation therein.

摘要： A method for controlling a DI fuel injector relying on measurement of a engine operating parameter, preferably fuel pressure in an associated fuel rail. Regimes of low fuel injector flow require lowered fuel rail pressure, allowing lowered peak and hold currents that afford quicker closing. Under low flow conditions, a prior art fixed peak current exceeds the current required for rapid opening of the fuel injector, and a prior art fixed hold current exceeds the current required for holding the valve open for the full duration of the open window. In the present invention, the peak and hold currents, and optionally peak and hold voltages, are varied as functions of fuel rail pressure, either continuously or stepwise. The result is full function of a fuel injector over the full range of fuel flow requirements while also providing the quickest possible response under all flow conditions.

摘要： A fuel rail assembly includes an integral pressure damper and an over-pressure stop to prevent the damper from flexing beyond it elastic limit. The rail assembly also includes injector cups formed outwardly relative to the rail to provide substantially unimpeded fuel flow to the injector. The fuel rail assembly further includes a damper cover to protect the damper from outside damage. The damper cover can be hermetically sealed to form an air chamber above the damper and opposite the fuel chamber in the fuel rail thereby providing a means for keeping the pressure differential between the chambers in an APDI fuel injection system substantially constant.
