FUEL STORAGE SYSTEM
First Claim
1. A fuel storage system for storing dimethylether (DME), a blend including DME, or other similar highly volatile fuel on a vehicle, the fuel storage system comprising 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, wherein the valve arrangement in the normal operating setting provides a fuel passage between the main storage tank and the expansion tank, and wherein 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, wherein the fuel storage system comprises a mechanical locking device located adjacent the fuel filling receptacle and configured to selectively lock the fuel filling nozzle in the fuel filling receptacle, the mechanical locking device being;
- 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.

Abstract
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.

30. Method for refuelling a fuel storage system for storing dimethylether (DME), a blend including DME, or other similar highly volatile fuel on a vehicle, the fuel storage system comprising 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, wherein the valve arrangement in the normal operating setting provides a fuel passage between the main storage tank and the expansion tank, and wherein 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 comprising:
-
inserting the fuel filling nozzle into the fuel filling receptacle; locking by means of a mechanical locking device the fuel filling nozzle in the fuel filling receptacle, such that the fuel filling nozzle is mechanically prevented from being disconnected from the fuel filling receptacle, wherein the valve arrangement is automatically set in the fuel filling setting; refuelling the main storage tank; unlocking the fuel filling nozzle from the fuel filling receptacle by positioning the valve arrangement in the normal operating setting; and removing the fuel filling nozzle from the fuel filling receptacle.
