Abstract
A fuel system for a direct injection engine having a fuel rail and a plurality of direct injection fuel injector assemblies mounted to the fuel rail. Each fuel injector assembly includes a mounting surface and a dampener made of a resilient material is disposed around this mounting surface. A bracket is secured to the engine and has a recess for each fuel injector assembly. Each fuel injector assembly is positioned in its associated recess so that at least a portion of the dampener is sandwiched between the fuel injector assembly mounting surface and a complementary mounting surface formed on the recess. A holder secures the injector assembly in its associated recess.
