US 2007/0163545 A1 · Isolated fuel delivery system

Abstract

An isolated fuel delivery system for an internal combustion engine includes a fuel rail with a clamping method operable to retain an isolating member with respect to the fuel rail. The isolating member operates to isolate the vibratory motion of the fuel delivery system form the attachment point or points. The attachment point is typically a cylinder head of the internal combustion engine. Additionally, an isolating ring assembly is provided having a first and second stiffening member with an isolating ring member disposed therebetween. The isolating ring assembly is disposed between a fuel injector of the isolated fuel delivery system and the cylinder head. The isolating ring member operates to isolate the vibratory motion of the fuel injector from the internal combustion engine.
