摘要： A fuel pipe assembly for supplying fuel to a fuel injector located within a bore of an engine cylinder head comprises a tube nut for connecting the fuel pipe to the fuel injector and a securing arrangement comprising a locking nut and a deformable clamp member for securing the fuel pipe within the tube nut. The tube nut comprises a tubular member defining an axial bore to receive the fuel pipe, a distal end shaped for cooperation with the head of the fuel pipe, and a proximal end having an attachment mechanism for engaging a compatible attachment mechanism of the locking nut. The locking nut has an axial bore to receive the fuel pipe, and an attachment mechanism for engaging a compatible attachment mechanism of the tube nut. The clamp member defines a bore to receive the fuel pipe and is deformable under compression. In a first state of engagement, the locking nut and tube nut define a volume therebetween that accommodates the clamp member in an unstrained configuration and the fuel pipe is able to move laterally. In a second state of engagement, the clamp member is compressed between the locking nut and tube nut into a strained configuration such that lateral movement of the fuel pipe is constrained.

摘要： A piezoelectric actuator comprises a co-fired stack of piezoelectric elements formed from a piezoelectric material and a plurality of positive internal electrodes interdigitated with a plurality of negative internal electrodes throughout the stack to define active regions of the piezoelectric material which are responsive to a voltage applied across the internal electrodes, in use. An external positive electrode connects with the positive internal electrodes and an external negative electrode connects with the negative internal electrodes. The actuator is characterized in that the stack further comprises means for deliberately creating artificial cracks within the stack at a location at which the artificial cracks do not give rise to a short circuit between the internal electrodes but serve to relieve stresses within the piezoelectric material.

摘要： An injection device for administering a reagent into an exhaust chamber of an internal combustion engine, comprising a device inlet and a device outlet and a sub-assembly held securely within a device housing. The sub-assembly comprises (i) valve housing defining a valve seat, (ii) valve means movable outwardly from the valve housing, away from the valve seat, to permit the reagent to be delivered into the exhaust chamber through the device outlet, whereby a force is applied to the valve means due to reagent delivered to the device inlet which serves to urge the valve means away from the valve seat, and (iii) bias means for applying a biasing force to the valve means which serves to urge the valve means against the valve seat so as to prevent delivery of the reagent through the device outlet into the exhaust chamber. The device housing is a separate part from the valve housing and has a housing bore within which the valve housing is held securely so as to hold the sub-assembly securely within the device housing.

摘要： A method for controlling the displacement of a stack of a piezoelectric actuator adapted for use in a fuel injector in order to control the fuel injection rate and volume. The method comprises driving a varying current through the stack during an opening phase including a first opening stage and a second opening stage; driving the stack during the first opening stage with a first opening current level for a first opening time period and driving the stack during the second opening stage with a second opening current level for a second opening time period. The second opening current level is less than the first opening current level and the current levels are selected so that the fuel injection rate in the opening phase includes a first portion corresponding to the first opening stage having a gradient that is steeper than a second portion corresponding to the second opening stage.

摘要： A fuel pressure regulation system for a compression ignition diesel engine. The system comprises a fuel supply line connected to an inlet of a transfer pump and a transfer pressure fuel line connected between the transfer pump outlet and the high pressure fuel pump inlet. A fuel filter is positioned in the transfer pressure fuel line and a fuel spill line fluidly connects a fuel pressure regulator to the transfer pressure fuel line at a point between the transfer pump outlet and the fuel filter. A fuel return line is connected between the fuel pressure regulator and the fuel supply line and a control fuel line is connected between the fuel pressure regulator and the transfer pressure fuel line. The fuel pressure regulator comprises a bore within which is located a valve member moveable from a non-regulating position of the fuel pressure regulator to a regulating position of the fuel pressure regulator. In use, any fuel entering the bore through a control fuel line connection acts upon a valve member thrust surface which results in a force acting to open the fuel pressure regulator. Any fuel entering the bore through the fuel spill line connection enters a region between the first end and the second end of the bore. There is provided a leak passageway connected from a point between the first and second ends and a fuel return line connection. In normal operating use, a fuel flow path from the fuel spill line connection to the fuel return line connection is kept open when the fuel pressure regulator is in the non-regulating position.
