Abstract: An exhaust valve arrangement for use in a combustion chamber (12) of a compression ignition internal combustion engine, includes a piston (72) which is movable outwardly from the combustion chamber (12) in response to pressure generated within the combustion chamber (12) as a result of combustion, and an outer sleeve (70) within which the piston (72) is movable. The outer sleeve (70) is an exhaust valve which is actuable between open and closed positions to open and close, respectively, an exhaust passage (40) from the combustion chamber (12). The exhaust valve arrangement further includes a pump chamber (77) for receiving fluid, and a pumping plunger (73) coupled to the piston (72) and movable with the piston (72) so as to pressurise fluid (e.g. fuel) within the pump chamber (77) as the piston (72) is urged outwardly from the combustion chamber (12). The pressure within the pump chamber (77) is proportional to cylinder pressure and is sensed by a sensor (14) which provides an output signal to an Engine Control Unit (ECU 16). An accumulator volume (125) receives fluid that is pressurised within the pump chamber (77). Where the fluid is fuel, the accumulator volume (125) is arranged to deliver fuel to one or more injectors (14) of a common rail fuel injection system. Alternatively the accumulator volume (125) may be arranged to deliver pressurised fluid to one or more engine systems e.g. for actuation purposes.

Abstract: 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 and which may therefore be used in a totalized flow calculation.
