The present disclosure is directed to a valve actuation assembly, with a valve (122), means for sensing (126), a cable (121), means for actuating the valve (122) by pulling on the cable (121) and a brush bearing. The cable (121) includes a brush bearing with bristles extending from the cable (121) to maintain the cable (121) at least generally centered within a channel as the cable moves in the channel. The bristles can be electrically conductive and can convey a voltage to an electrode pair near the valve to ionize at least a portion of the fuel to urge the fuel from the injector through the valve. |
