摘要： A fluid quick connector has an integrated pressure sensor for sensing the pressure of fluid in the quick connector. The pressure sensor is mountable in a housing which may be an integral molded part of the quick connector housing, a separate housing fixedly connected to the quick connector housing, or a separate housing latchingly coupled to the quick connector housing. An orifice in the pressure sensor and/or pressure sensor housing is disposed in communication with the bore extending through the quick connector housing for measuring the pressure of fluid within the quick connector bore. An electrical connector may provided for communicating electrical signals representative of the sensed fluid pressure by the pressure sensor externally of the quick connector.

摘要： Electro-hydraulic engine valve actuation system providing an actuator and an actuator control system. The actuator includes primary and secondary actuation chambers, defined by a piston, connected to the engine valve, and characterized by increasing and correspondingly decreasing chamber volumes, as the piston is urged away from neutral position. A fluid inlet is connected to a flow control valve. A control valve includes an actuator, and has flow states for controlling flow between two fluid inlets and a fluid outlet. The control valve includes first and second opposed, control chambers, each connected to the actuator. There is a spring in the second control chamber. The actuator of the flow control valve is controlled to a first and second state, and there is an electrically uncontrolled third flow state. There is a pair of temperature-compensated orifices which create internal feedback, with the control chambers, between the engine valve motion and the control valve position.

摘要： The durability of a fuel cell having a polymer electrolyte membrane with an anode on one surface and an oxygen-reducing cathode on the other surface is improved by substituting electrically conductive titanium carbide or titanium nitride particles for carbon particles as oxygen-reducing and hydrogen-oxidizing catalyst supports. For example nanosize platinum particles deposited on nanosize titanium carbide or titanium nitride support particles provide good oxygen reduction capability and are corrosion resistant in an acid environment. It is preferred that the catalyst-on-titanium carbide (nitride) particles be mixed with non-catalyst-bearing carbon in the electrode material for improved electrode performance.

摘要： A process for adjoining materials by friction stir welding. Two adjacent material segments are heated by localized heating to raise the temperature of each segment along the intersection to a discrete predefined level below the melting point of the particular segment of material being heated. In conjunction with this discrete localized heating, friction stir welding is carried out along the intersection to form the solid state bond.

摘要： A method is provided for control of transition between combustion modes of a direct-injection engine operable in a homogeneous charge compression ignition (HCCI) mode at lower loads and a spark ignition flame propagation (SI) mode at higher loads. The engine includes a variable valve actuation system including two-step high and low lift valve actuation and separate cam phasing for both intake and exhaust valves. The method includes operating the engine at steady state, with fuel-air-exhaust gas mixtures at predetermined conditions, for each speed and load, and controlling the engine during mode changes between the HCCI mode and the SI mode by switching the exhaust and intake valves between low lift for HCCI operation and high lift for SI operation. High load may be an SI throttled mode with an intermediate unthrottled mode (SI/NTLC} in which transition between HCCI and SI/NTLC modes requires switching only the exhaust valve lift and transition between SI/NTLC and SI throttled modes requires switching only the intake valve lift, with predetermined phase adjustments in the valve timing phasing.

摘要： A fuel cell electrocatalyst layer having increased voltage cycling durability. The electrocatalyst layer comprises annealed platinum particles having an average particle size diameter from about 3 to about 15 nm deposited on a support structure. The platinum particles are annealed at a temperature from about 800 to about 1,400°C for a time period such that the surface area is reduced by about 20% as compared to the original surface area. In various embodiments, the electrocatalyst layer retains an electrochemical surface area that is greater than 50% of an original electrochemical surface area after about 15,000 voltage cycles in the range from about 0.6 to about 1.0 V.

摘要： The durability of a fuel cell having a polymer electrolyte membrane with an anode on one surface and an oxygen-reducing cathode on the other surface is improved by replacing conductive carbon matrix materials in an electrode with a matrix of electrically conductive metal compound particles. The electrode includes a catalyst supported on a nanosize metal oxides and electrically conductive nanosize matrix particles of a metal compound. One or more metal compounds such as a boride, carbide, nitride, suicide, carbonitride, oxyboride, oxycarbide, or oxynitride of a metal such as cobalt, chromium, nickel, molybdenum, neodymium niobium, tantalum, titanium, tungsten, vanadium, and zirconium is suitable. For example, the combination of platinum particles deposited on titanium dioxide support particles mixed in a conductive matrix of titanium carbide particles provides an electrode with good oxygen reduction capability and corrosion resistance in an acid environment.
