Abstract
A coaxial quill assembly is used for supplying gaseous and liquid fuels from separate common rails to individual fuel injectors of a compression ignition engine. Each coaxial quill assembly includes a matched pair of an outer quill and an inner quill that are matched based upon a fuel system dimensional specification that causes both the inner and outer quills to sealingly engage a common conical seat of a fuel injector. During pre-installation handling, the matched pair of inner and outer quills are retained together with a retainer.
