Abstract
A fuel injection system for an internal combustion engine includes a fuel injector pocket, formed within a cylinder head, for housing an injector which sprays fuel into a combustion chamber defined by the cylinder head and a piston crown. The injector is mounted with a conical isolator which is loaded at a lower, elastic rate during lower power operation, with the conical isolator being stacked solid between a tapered portion of the injector and a corresponding tapered portion of the cylinder head during high power operation of the engine and injection system. The isolator controls unwanted injector ticking noise, while protecting the integrity of the injector's tip seal by preventing excessive axial displacement of the injector during higher load operation.
