  • Fuel injection system for internal combustion engine with injector isolator
    Patent number: 7827964
    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 an isolator which is loaded at a lower, elastic rate during lower power operation, with the elastic load element being stacked solid and subject to higher rate column loading 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.
    Type: Grant

  • Fuel injection system for internal combustion engine with injector isolator ring
    Patent number: 7823565
    Abstract: A fuel injection system for internal combustion engine includes an injector mounted within a pocket formed in the cylinder head, and an isolator which defines a radial clearance gap with the injector pocket. The isolator expands radially outwardly into a clearance gap in response to axially directed force imposed upon the isolator by the injector, so that a dual rate force/displacement effect is achieved by the isolator.
