Abstract
A fuel injection system includes a fuel supply rail, a fuel injector configured to control the delivery of fuel from the fuel supply rail, and a noise filtering device engaging an upstream end of the fuel injector and/or positioned at least partially within the fuel injector. The noise filtering device defines a fuel passage configured to direct fuel from the fuel supply rail into the fuel injector. The noise filtering device can include one or more of several features including a pocket, a wrap-around shape to conform to the inlet end of the fuel injector, a face-sealing portion, a compression section, and a plurality of parallel restriction passages.
