Abstract
An internal combustion engine includes a fuel system having a first fuel rail with an integrated diverter portion coupled to a high-pressure pump and separated from a common rail portion by a flow restriction device. The first fuel rail includes a pressure sensor coupled to the diverter portion at one end and a control valve coupled to the common rail portion at the other end of the same fuel rail. In V-engine embodiments, a second fuel rail communicates with the integrated diverter portion of the first fuel rail. In one embodiment, components including the first and second fuel rails, a pressure sensor, and a pressure or volume control valve are externally mounted outside the engine valve cover.
