摘要： An arrangement for supplying fuel from a fuel pressure source located on an outside of an engine enclosure to a fuel injector located on an inside of the engine enclosure includes a fuel pipe for transporting fuel from the fuel pressure source to the fuel injector via an opening in the engine enclosure, and a seal for sealing the fuel pipe at the opening. The seal includes a first part configured for a sealing contact around the fuel pipe and a second part configured for a sealing contact around a sleeve extending around the opening. An internal combustion engine provided with such an arrangement and a method for providing an internal combustion engine with such an arrangement are also provided.

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 fuel storage system is provided for storing dimethylether (DME), a blend including DME, or other similar highly volatile fuel at a vehicle. The fuel storage system including a main storage tank, an expansion tank, a fuel filling receptacle configured to receive a fuel filling nozzle of a filling station, and a valve arrangement having at least a normal operating setting and a fuel filling setting. The valve arrangement in the normal operating setting provides a fuel passage between the main storage tank and the expansion tank, and the valve arrangement in the fuel filling setting both provides a fuel passage between the fuel filling receptacle and the main storage tank and prevents fuel flow between the main storage tank and the expansion tank. The fuel storage system is configured to mechanically prevent disconnection of the fuel filling nozzle from the fuel filling receptacle unless the valve arrangement is in the normal operating setting. A corresponding method, as well as a further example embodiment of the fuel storage system, are also provided.
