摘要： An arrangement and method for recirculating highly pressurized fuel from a fuel rail (12) back to a high pressure pump inlet in which a fuel outflow is controllably allowed from the fuel rail (12) into a nozzle (48) to form a high pressure stream of fuel directed into a port (52) connected to the inlet of the high pressure pump (24) and a flow of fuel from a low pressure supply pump (22) is merged into the stream by a surrounding annular flow pattern. This uses the energy of high pressure fuel to increase the pressure at the inlet of the high pressure pump (24) and greatly reduces the tendency for the fuel vapor to form.

摘要： A key fob (10) for signaling a receiver on a vehicle includes a housing (12) and a transmitter (14) capable of transmitting multiple signals. The signals actuate multiple vehicle devices on the vehicle. Switches to control the signals include at least one dome (16) protruding through the housing for initiating transmission of a signal. The dome includes a first element (20) depressable for initiating a first signal and a second element (22) depressable independently of the first element for initiating a second signal different from the first signal. The first element (20) protrudes from the housing to a different height than the second element (22). Thus, the elements can be easily actuated separately from each other.

摘要： An electromagnetically operable fuel injector, for a gaseous fuel injection system of an internal combustion engine is disclosed, the injector having a generally longitudinal axis, a ferromagnetic core, a magnetic coil at least partially surrounding the ferromagnetic core, and an armature magnetically coupled to the magnetic coil and being movably responsive to the magnetic coil. The armature actuates a valve closing element which interacts with a fixed valve seat of a fuel valve and is movable away from the fixed valve seat when the magnetic coil is excited, the armature having a generally elongated shape and a generally central opening for axial reception and passage of gaseous fuel from a fuel inlet connector positioned adjacent thereto. The fuel inlet connector and the armature are adapted to permit a first flow path of gaseous fuel through a working gap between the fuel inlet connector and the armature and between the armature and the magnetic coil as part of a path leading to the fuel valve. At least one first fuel flow aperture extends through a wall portion of the armature to define a second flow path of gaseous fuel as part of a path leading to the fuel valve. The fuel flow aperture is dimensioned to provide predetermined fuel flows past said armature and through the armature. In the preferred embodiment the combined flow area across the working gap and through the working gap between the armature and the magnetic coil and valve body shell exceeds the area available for fuel flow through the armature. A method of directing gaseous fuel through the fuel injector is also disclosed.

摘要： A mounting arrangement with a fuel rail (12) having a plurality of fuel injector cups (14), a plurality of fuel injectors (16), and a clip (18). The fuel injector cups include a cylindrical tube defining a longitudinal axis, a fuel rail mounting section disposed at a first end of the tube, and a lip (28) at a second end of the tube. Each of the fuel injectors corresponding to one of the plurality of fuel injector cups. The fuel injectors have a housing with a retention groove. The clip engages both the lip (28) of the fuel injector cup and the retention groove in the housing of the fuel injector to secure the fuel injector to the fuel injector cup and allow the fuel injector to reciprocate along the longitudinal axis.

摘要： There is shown an electric motor control of the engine valves of an internal combustion engine. A brushless torque actuator controls the rotation of a cam member which provides the appropriate lift to the engine valve to move the valve from the closed to the open position. The electronic control which is connected to the actuator includes a look-up table for controlling the timing of the engine in accordance with the operation of the internal combustion engine. The electronic control operates to return the cam member to its home position closing the engine valves.

摘要： A high pressure direct injection fuel system includes a low pressure fuel supply; a venturi pump including a variable orifice, first and second inlets and an outlet, the low pressure fuel supply connected to the first inlet of the venturi pump; a high pressure pump connected to the outlet of the venturi pump; a fuel rail connected to an outlet of the high pressure pump, the fuel rail including at least one fuel injector and a pressure sensor; a high pressure regulator connected to the fuel rail; a return flow line connected between the fuel rail and the second inlet of the venturi pump; and an electronic control unit connected to the pressure sensor and the high pressure regulator. The variable orifice venturi pump suppresses gas formation in the return fuel flow thereby allowing the use of a lower fuel supply pressure.

摘要： Significant improvement in limiting the dispersion of an injected fuel stream is obtained by constructing the tip end of the needle valve (21) to have a proximal portion and a distal portion wherein the proximal portion is a surface (52) in the form of a segment of an imaginary sphere that is geometrically defined by imaginary spaced-apart, parallel planes passing through such imaginary sphere, that surface of the proximal tip portion being that portion of said tip end that seats on and unseats from a frustoconical seat (32) as the valve is reciprocated, and the distal tip portion (56) is a frustoconical surface (54) extending tangentially from the proximal tip portion. Such limiting of the dispersion of the injected stream provides better targeting of the injected fuel.

摘要： A control arrangement for a deployable airbag of a vehicle is provided with first (31) and second (32) airbag controllers for receiving a fault signal at the first airbag controller (31), and for producing at the second airbag controller (32) a deployment command signal to deploy the airbag. The second airbag controller is provided with a communication controller (51) for receiving the deployment command signal and a squib fuse (57) is fired. An energy transfer arrangement is coupled (52) to the communication controller and the squib fuse to transfer energy to the squib fuse in response to the deployment command signal. The squib fuse requires a predeterminable minimum quantum of energy to effect the firing thereof. A heater (56) provides a radiated preheat to the squib fuse whereby the quantum of energy applied to fire the squib fuse is exceeded. The radiated preheat energy is monitored (58) and controlled.

摘要： An automatic injector insertion station (10) for inserting a fuel injector mounting end (14) into a fuel rail cup (20) includes a housing (22) and an injector nest (24) moveable relative to the housing (22). The nest (24) includes first and second ends (26, 28). The first end (26) includes a support (30) for supporting and guiding the injector (12), and is moveable between a preload position, wherein the fuel injector mounting end (14) is adjacent the fuel rail cup (20), and an insertion position, wherein the mounting end (14) and o-ring (16) are mounted in the fuel rail cup (20). A compression spring (32) is mounted in the housing (22) and connected with the second end (28) of the injector nest (24). A piston and cylinder arrangement is operable for compressing the compression spring (32) to a loaded compressed position. The injector nest (24) is moveable by the compression spring (32) compressive force from the preload position to the insertion position to assemble the fuel injector (12) and o-ring (16) into said fuel rail cup (20) through linear spring force, thus preventing damage to the o-ring (16).
