Abstract: A control valve arrangement for use in controlling fuel pressure within a control chamber (30) includes a control valve member (32) which is movable between a first position in which the control chamber (30) communicates with a source of high pressure fuel, and a second position in which the control chamber (30) communicates with a low pressure fuel drain and communication between the control chamber (30) and the source of high pressure fuel is broken. The control valve arrangement also includes restricted flow means (55, 70, 86) for restricting the rate of flow of fuel from the control chamber (30) to the low pressure fuel drain when the control valve member (32) is moved from the first position to the second position. It is desirable for the restricted flow means to be configured and arranged such the rate of flow of fuel from the source of high pressure fuel to the low pressure drain for the period of time for which the control valve member (32) is moving between the second position and the first position is also restricted.

Abstract: A fuel system for use in an internal combustion engine, particularly of the type provided with an after treatment device for reducing emissions levels, comprises a fuel pump (10) having a pumping cycle during which fuel is pressurized to a high level within a pumping chamber for delivery to an injector (14). The injector (14) is arranged to provide a primary fuel injection event, and a secondary fuel injection event within the same pumping cycle, in use. The injector (14) includes a valve needle (16) which is engageable with a valve needle seating to control fuel delivery through an injector (14) and injection control valve means for controlling movement of the valve needle (16) so as to control the primary and secondary fuel injection events. The primary injection event may be a main injection of fuel, and the secondary injection event may be a late-post injection of fuel for regeneration of the after treatment device. Engine having an after treatment device.

Abstract: A control valve (16) of an engine fuel system includes a valve member which is coupled to an armature (17) and is moved to engage a seating when a winding (18) is energised. The current flow in the winding is first allowed to rise to a peak value to initiate movement of the armature and valve member at which time the winding is disconnected from the supply. The decay of current in the winding is controlled using two rates of current decay to ensure that the valve member moves into engagement with the seating with the minimum of bounce.
