    Abstract: A method of controlling a drive circuit (20a, 20b, 20c) for an injector arrangement including at least one injector (12; 12a, 12b) having capacitive-like properties, the drive circuit including at least one inductor (L1; L11; L21; L22) and a bidirectional current path (26) coupled to the at least one injector; selector means (Q13, Q14, Q23, Q24) for selecting one of the at least one injector(s) (12; 12a, 12b); and switching means for controlling current flow through the at least one injector (12; 12a, 12b) and the at least one inductor (L1; L11; L21; L22) to open and close the at least one injector, wherein the switching means includes a discharge switch means controllable to cause a charging current (I CHARGE ) to flow through the bidirectional current path (26) during a charge mode so as to charge the at least one injector, and discharge switch means (Q2; Q12; Q22) to cause a discharge current (I DISCHARGE ) to flow through the bidirectional current path (26) during a discharge mode so as to discharge the at least one injector. The method comprises selecting an injector (12; 12a, 12b) to permit a discharging current to be supplied thereto so as to initiate an injection event; activating the discharge switch means (Q2; Q12; Q22) to supply the discharging current to the selected injector until the voltage across the selected injector reaches a predetermined discharge level (V discharge ); and enabling the discharge switch means (Q2; Q12; Q22) for a time period (t1) after the predetermined discharge level (V discharge ) has been reached thereby reducing voltage ringing in the drive circuit.

The filter assembly (1) further comprising a disposable filter cartridge (4), housed within the disposable filter body (2), and housing a filter member (30) for filtering particulate contaminates from a flow of fluid through the filter assembly (1). The filter member (30) is hollow and the disposable filter cartridge (4) further comprises an impermeable wall (32) that extends axially through the filter member (30). The central support (3) is separable from the disposable filter body (2) and removable from the openings (14, 16) to allow disposal and replacement of the filter body (2) and the filter cartridge (4) during servicing. The central support (3) may include a series of integral heating elements (49) which serve to provide a heating effect to the fluid flow, prior to passage through the filter member (30).

    Abstract: A method of controlling combustion in an internal combustion engine with exhaust after treatment device is proposed, wherein upon detection of a request for a regeneration event of the exhaust after treatment device, a regeneration combustion mode comprising a pilot injection and a retarded main injection is operated. During the regeneration combustion mode the injection timing of the main injection is controlled so that its retard is not later than a retard threshold that is determined as the maximum timing retard to provide the desired torque, but with an injected fuel quantity not exceeding a maximum fuel quantity given by a stored smoke-limit map.
