FUEL SYSTEM FOR A COMBUSTION ENGINE HAVING LOCAL LEAKAGE DETECTION

摘要

The application relates to a connector (11) for connecting at least a portion of a double-wall tubing (9) to a high-pressure line (4) and a fuel system having a high pressure line (4), a double wall tubing (9) and connector for coupling the double-wall tubing (9) to the high-pressure line (4). The connector (11) is configured to establish a fluid connection between a portion of the double wall tubing (9) and the high pressure line (4). The connector also provides a fluid detection passage, and a fluid connection between another portion of double wall tubing and said fluid detection passage. The application also relates to a method for detecting a leakage in a fuel system of the above type, having a plurality of first detection units and a second detection unit, in which fuel leakage, which may stem from different areas of the fuel system, may be detected by at least one of said first and second detection units.
