METHOD AND SYSTEMS FOR A LEAKAGE PASSAGEWAY OF A FUEL INJECTOR

摘要

METHOD AND SYSTEMS FOR A LEAKAGE PASSAGEWAY OF A FUEL INJECTOR Various methods and systems are provided for a leakage passageway (230) for a fuel injector (118) of a common rail fuel system (114). In one embodiment, a fuel injector (118) for an engine comprises an injector accumulator (204), an injector flow limiter valve (202) configured to control a flow of fuel from a common fuel rail (114) and into the injector accumulator (204), and a leakage passageway (230) coupled between the injector accumulator (204) and an inlet (302) of the injector flow limiter valve (202), the leakage passageway (230) bypassing the injector flow limiter valve (202).
