摘要： In accordance with preferred embodiments of the invention a timing adjustment device includes a cam follower that is engaged between an overhead cam and an injector rocker arm, and is mounted on a rotatable eccentric shaft. The geometry of the eccentric shaft and cam follower is designed so that, as timing is varied by rotation of the eccentric shaft, no change is produced in the vertical height of the rocker arm when the cam shaft is on the outer base circle and the injector is bottomed, in order to assure that the "mechanical crush" of the PT type injector is constant despite changes in timing. In a first application of the timing arrangement, it is used together with a simple injector, which does not utilize a multi-plunger arrangement to form a hydraulic link, to achieve lower parasitic losses. To obtain independent control over injection pressure and timing, a fuel injector in which a hydraulic link is formed between plungers of a multi-plunger arrangement is used with the timing arrangement in order to allow the injection pressure to be maintained constant over a wide range of engine speeds without interfering with engine timing.

摘要： An electronically controlled fuel supply system is provided for employing a plurality of fuel injectors which maximize SAC pressures under both low speed and high speed operating conditions and are capable of sustaining SAC pressures in excess of 30,000 psi. The fuel supply system of the present invention includes a gear pump which supplies pressure-modulated fuel to a fueling channel and to a timing channel and from there to a plurality of injectors. Fuel pressure regulator means and timing fluid pressure regulator means are provided in the fueling and timing channel, respectively. An electronic control unit receives information relating to engine operating conditions from a plurality of sensors and actuates the fuel pressure regulator means and the timing fluid pressure regulator means to adjust the pressure as required for the specific engine operating conditions. The timing fluid is delivered to the injectors by the present system at a pressure sufficient to sustain a hydraulic link within the injector of the length necessary to maintain high SAC pressures during injection. Several embodiments of a fuel supply system which achieves these objectives are disclosed. A mounting integral with the cylinder head for an electronically controlled injector fuel supply system is also provided.

摘要： A fuel injection system is provided for a multicylinder internal combustion engine. Each cylinder is provided with at least one fuel injector. The system includes a cam-operated pumping plunger which maintains fluid pressure within an accumulator and controls the intermittent application of fluid pressure from the accumulator through a first chamber in which the plunger moves to one end of a metering plunger. The opposite end of the metering plunger coacts with a second chamber in which the metering plunger moves to define a cavity into which fuel is supplied for subsequent feeding to the cylinder injector. Fuel enters the cavity during those periods when the metering plunger is not subjected to the accumulator fluid pressure, the latter being under the control of the pumping plunger. The pumping plunger reciprocates within its chamber and is rotatable about its longitudinal axis. An elongated groove is formed in and encompasses the exterior of the pumping plunger. The effective axial length of the groove may be varied depending upon the relative position of rotation of the pumping plunger within the first chamber, so that the time may be changed as to when the accumulator fluid pressure is intermittently supplied to the metering plunger via the first chamber and during the pumping stroke of the plunger. The rotational adjustment of the pumping plunger is controlled by external means which may be responsive to the operational demands of the engine.

摘要： A communication interfacing device which allows for automatically coupling two diverse communication systems which transmit audio information. The device further includes a telephone answering circuitry which allows a telephone to be interfaced automatically with radio transceivers, computers, and intercoms such that the device will automatically connect and disconnect incoming telephone calls to and from such devices. The system employs voice responsive controllers which affect the timing cycles of individual communication channels to allow for a two-way conversation between remote stations utilizing diverse communication devices. The controllers allow for discriminating between incoming and outgoing calls on a priority basis such that channel switching modes cannot be interrupted until a conversation on the priority channel or an audio signal ceases.
