Abstract
A common rail single fluid injection system includes fuel injectors and control valve assemblies with an internal cooling fluid circuit to improve overall life and performance of the injector. This is accomplished by supplying cooling fluid to the injector and allowing the same to come in direct contact with one of the hottest locations within the fuel injector; the high-pressure leak split spot. By providing cooling fluid directly to this location and then allowing the cooling fluid to drain out of the injector, the present disclosure effectively and efficiently manages thermal loads within the injector.
