摘要： A fuel injection apparatus for an internal combustion engine includes a fuel supply passage and a valve arrangement for controlling fuel pressure within the fuel supply passage. The valve arrangement includes a valve member movable between an open position in which the fuel supply passage communicates with a low pressure fuel drain and a closed position in which communication between the fuel supply passage and the low pressure fuel drain is prevented. The valve arrangement comprises damping means for controlling and/or damping movement of the valve member between the closed and open positions.

摘要： The invention relates to a fuel injection system of the common rail type having a rail body comprising a central bore and one or more outlet bores in fluid communication with the central bore for communicating with a respective fuel injector. The outer circumference of the rail body is substantially oval in cross-section and is thicker in cross-section in a direction substantially perpendicular to the outlet bore axis as compared to the thickness in cross-section substantially parallel to the outlet bore axis. By increasing the thickness of the rail body in this way, stresses at the intersection of the intersection of the central bore with the outlet holes may be reduced by up to 10% or more, thereby increasing the acceptable cycled running pressure of the system.

摘要： A fluid delivery system for delivering a metered dose of fluid from a supply tank (28) to a downstream chamber or vessel (10), comprises a pump apparatus (20) comprising a pump plunger (32) which is operable to perform a pumping stroke under the control of an electromagnetic actuator (36), including a solenoid (36a), to effect delivery of the fluid and a control unit (24) for supplying an input signal (58) to the solenoid (36a) to initiate a current flow to the solenoid (36a) and thereby initiate movement of the pump plunger (32). An electronic device (54) provides an output signal to indicate that movement of the pump plunger has stopped at the end of the pumping stroke, and a timer determines a time difference between the input signal (58) being supplied to the solenoid (36a) and the output signal being output by the electronic device (54). A processor (26) compares the time difference with a predetermined time difference and determines, as a result of the comparison, whether or not the pump plunger (32) has performed a valid pumping stroke in which an intended volume of fluid is displaced.

摘要： A method and apparatus for controlling a fuel pump assembly comprising a plurality of pump elements for delivering fuel at high pressure to a rail volume, each of the pump elements comprising a plunger which is driven by an associated cam to perform at least one pumping event per engine revolution and a control valve for controlling fuel flow into and/or out of the pump chamber. Each pumping event corresponds to an associated cam lobe of the associated cam. The method comprises, for each pumping event of each pump element, controlling the control valve of said pump element in response to an output control signal derived from at least one previous pumping event. The output control signal is derived by measuring fuel pressure within the rail volume to derive a measured rail pressure value; and comparing the measured rail pressure value with a demanded rail pressure value to derive a rail pressure error. A proportional and integral calculation is performed on the rail pressure error to derive a proportional term for the rail pressure error and an integral term for the rail pressure error. The proportional term and the integral term are combined to derive the output control signal.Monitoring of the integral term for each pumping event of each pump element provides a means for identifying and diagnosing a fault condition within the fuel pump assembly or associated fuel system.
