摘要： A device comprises an armature movable in a first direction and a second direction for causing a needle to contact and separate from a seat assembly. Stop means provide a motion stop in at least the first direction. Damping means are applied to the needle for reducing bounce of the needle when the needle contacts the stop means, by altering spring rates and vibration modes of the needle.

摘要： A fluid-pressure indicator includes a housing having a first region and a second region. A pressure-responsive member is disposed in the first region and is movable between an expanded state and a compressed state. An indicator disk is viewable through the pressure-responsive member when the pressure-responsive member is in the compressed state and is obscured from view through the pressure-responsive member when the pressure-responsive member is in the expanded state. A diaphragm is movable from a relaxed state to a deflected state in response to pressure within the second region exceeding a threshold pressure and prevents fluid communication between the first region and the second region. The diaphragm additionally causes the pressure-responsive member to move from the expanded state to the compressed state when the pressure exceeds the threshold pressure.

摘要： A valve damping piston and a cam follower piston have telescopic sliding fits in opposite ends of a through-bore in the lifter housing. A pressure chamber is cooperatively defined within the housing between the two pistons, and is communicated to the engine oil supply. A lash adjusting piston has a telescopical sliding fit with the exterior axial end of the damping piston, and the two cooperatively define between themselves a lash adjusting chamber. The lash adjusting chamber is communicated to the pressure chamber by an axial segment of the telescopic sliding fit of the damping piston to the housing. The clearance provided by this axial segment creates a flow restriction that results in the pressure in the lash adjusting chamber being appreciably lower, 50% for example, than the pressure in the pressure chamber. The damping piston contains a circumferential groove that is directly communicated to the termination of the axial segment. A radial and then an axial hole in the damper piston communicate the groove to the lash adjusting chamber. 00

摘要： Apparatus and method for integrating mass air flow for a specified cylinder event in the intake tract of an internal combustion engine. The respective outputs of a mass air flow sensor and a directional air flow sensor are used to determine an accurate net integrated value of mass air flow. The magnitude of mass air flow is sampled and electronically integrated several times during each specified engine event in either a positive or negative sense (depending upon air flow direction) to obtain a net mass air flow value, which is then input to a A/D converter and then a microprocessor in an engine electronic control unit for use in engine management control.

摘要： A variable camshaft timing system for an internal combustion engine varies the relative angular position between the intake camshaft and the exhaust camshaft by controlling the path of the timing belt means. A first belt means is interconnected at one end of the engine between the crankshaft and the exhaust camshaft. At the other end of the engine the intake camshaft and the exhaust camshaft are connected by a second belt means for rotating the intake camshaft from the rotational drive supplied via exhaust camshaft. Idler arms are positioned for controlling the path and tension in the second belt means for varying the timing of the intake camshaft relative to the exhaust camshaft. A motor means operates to position the idler arms through a positioning cam means. The motor is controlled from an electronic control unit which receives signals indicating the engine operating characteristics and through a look-up table steps the positioning cam means to pivot the idler arms to rotate the intake camshaft relative to the exhaust camshaft thereby changing the intake valve timing.

摘要： A fuel metering apparatus, for supplying metered fuel to an associated combustion engine, has an idle fuel metering and supply system comprising adjustable valving means which, in turn, comprises a discharge orifice means and cooperating valving member which is adjustably selectively positioned with respect to such orifice means in order to thereby establish a desired metered rate of fuel flow through the thusly determined effective flow area of the orifice means for a particular pressure differential thereacross; the adjustable valving member is generally contained within a cooperating body member or portion and access to the valving member, subsequent to it being selectively positioned, is prevented by closure members placed in position after the said selective positioning of said valving member.

摘要： An active fuel pressure pulsation cancellation technique includes receiving, at a controller of an engine having a camshaft-driven fuel pump, an unfiltered fuel pressure signal indicative of a measured pressure of fuel in a fuel rail. The technique includes detecting, at the controller, fuel pressure pulsations in the fuel rail based on the unfiltered fuel pressure signal. The technique includes generating, at the controller, a cancellation signal based on an opposite polarity of the fuel pressure pulsations. The technique also includes controlling, by the controller, an actuator associated with the fuel rail using the cancellation signal to cause the actuator to generate liquid-borne cancellation pulsations that cancel the fuel pressure pulsations in the fuel rail.
