摘要： A fuel injection system for supplying pressurised fuel to a fuel injector (50), the fuel injection system comprising an accumulator volume (59) for supplying fuel at a first injectable pressure level (P1) to the fuel injector (50) through a fuel supply passage (52), pump means (63) for increasing the pressure of fuel supplied to the injector (50) to a second injectable pressure level (P2), and valve means (62, 162, 262, 362) operable between a first position in which fuel at the first injectable pressure level (P1) is supplied to the injector (50) and a second position in which communication between the injector (50) and the accumulator volume (59) is broken so as to permit fuel at the second injectable pressure (P2) to be supplied to the injector. The injection system may include valve means in the 15 form of a three-position valve (262) or may include a shut off valve (464; 1464) for controlling the supply of fuel through the fuel supply passage (52).

摘要： 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.

摘要： 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.
