Abstract
A hybrid fuel injection system which allows electronic control over the injection processes, wherein selective rate shaping and multiplicity of injections is possible. The hybrid fuel injection system consists of an add-on common rail system (CRS) which provides supplemental fuel injections with respect to the main fuel injections provided by a unit pump system (UPS). Additionally, the CRS can serve to provide fuel injections as necessary to effect a 'limp-home' mode of engine operation in the event of a failure of the UPS. Both the CRS and the UPS use common fuel supply, return, injector, and electronic controller.
