摘要： A fuel injection system includes a first high pressure fuel source, a return channel connected to a second low pressure fuel source, a residual pressure regulator having an inlet and an outlet connected to the return channel, and a fuel injector having a control valve arrangement comprising an inlet, an outlet and a return port, a fuel injection nozzle having an outlet chamber, an injection outlet, and a needle member in the outlet chamber. The needle member is biased to a closed position to block fluid communication between the outlet chamber and the injection outlet, and to open fluid communication by a pressure in the outlet chamber. The residual pressure regulator is connected to a spill valve to regulate pressure to a residual pressure higher than the pressure in the return channel and lower than the pressure of the first fuel source.

摘要： A method for operating a switching arrangement of an energy storage system, the energy storage system comprising a plurality of parallelly arranged battery packs and the switching arrangement comprising an associated contactor for each battery pack, the contactors being configured to connect and disconnect the battery packs relative a load by closing and opening, respectively. The method comprises disconnecting the battery packs from the load by means of the contactors such that the battery packs are disconnected in a sequence in which one contactor is opened last and thereby subject to increased disconnection wear, controlling the sequence in which the battery packs are disconnected in such a way that the increased disconnection wear is accounted for and used to distribute contactor wear among the contactors during subsequent disconnections of the battery packs from the load.
