Abstract
Fuel injectors used in present day applications are normally requiring high pressure injection, short injection times and split or modified injection. Thus, this type of injection inherently produces an excess of noise. The present fuel injector assembly (22) overcomes the above deficiencies by controlling the noise emitted from a fuel injector (33). For example, as an actuation system (27) operates the fuel injector (33) the noise created by the opening and closing of the fuel injector (33) is absorbed within an isolator (34). As the fuel injector assembly (22) is installed, the fuel injector assembly (22) is positioned within a bore (26) with the fuel injector assembly being in a second position (29). And, a plurality of fasteners (28) are tightened to a predetermined value moving the fuel injector assembly (22) into a first position (24). Additionally, the fuel injector assembly (22) remains seated with respect to a cylinder (14) as the isolation material of the isolator (34) is biased positioning the fuel injector assembly (22) into the first position (24).
