A fuel injection system includes a fuel injector socket including a first attachment feature and a fuel injector including a second attachment feature that corresponds with the first attachment feature. The first attachment feature engages with the second attachment feature connecting the fuel injector to the fuel injector socket and preventing rotational movement of the fuel injector relative to the fuel injector socket. The corresponding attachment features not only enable simple connection and disconnection of a fuel injector to a fuel injector socket of a fuel rail, but can also be integrated into existing injector to fuel rail assembly processes and are applicable in any fuel injection system. The corresponding attachment features may be used with metal fabricated fuel rail assemblies as well as for fuel rail assemblies where the manifold supply tube and the fuel injector sockets are overmolded with a plastic material.

An electro-hydraulic valve assembly includes a center pole mounting an electric solenoid assembly and slidably received in a valve boss. The solenoid assembly controls the fluid pressure in a chamber defined in the center pole. Fluid in the chamber is biased against a deflectable disc which controls fluid flow through the valve assembly. Control of electric current to the solenoid assembly controls fluid pressure in the chamber and, thus, fluid flow through the valve assembly. When utilized with a damper and a controller, the present valve assembly provides continuously variable damping in real time.
