Abstract

A pump and rail assembly includes a plurality of quills that are compressed between quill seats on a pump and an output rail. A rail pressure control valve and a rail pressure sensor are attached to respective ends of the output rail. An inlet throttle valve is attached to a housing of the pump and rail assembly. Depending upon the application, the output rail may supply fuel to a first injection bank that includes a plurality of fuel injectors in a first common rail, and a second fuel injection bank that includes a second common rail and a plurality of fuel injectors. Different engines having different numbers of cylinders may use similar pump and rail assemblies that each include a plurality of quills, a plurality of pumping elements positioned in a pump housing and an output rail. The quills for each of the different engine applications are interchangeable but differ in number. In addition, the pumping elements of each of the different engine applications are also interchangeable but differ in number.
