Abstract
An engine assembly may include a cylinder head, a cam cover and a fuel rail assembly. The cylinder head may define intake and exhaust ports and the cam cover may be fixed to the cylinder head. The fuel rail assembly may include a fuel rail, a bracket assembly and a fuel injector. The bracket assembly may be fixed to the fuel rail and may include a fastener and an isolation member. The fastener may be engaged with the cam cover and may secure the fuel rail thereto. The isolation member may be located between the fuel rail and the cam cover to isolate vibration therebetween. The fuel injector may be in communication with the fuel rail and may extend into a combustion chamber defined by the cylinder head at a location between the intake and exhaust ports.
