Abstract

A fuel injector comprises a barrel, a plunger, and a port. The plunger is disposed in a bore in the barrel such that it intersects the port disposed in the barrel. The plunger has an injection rate shaping device and a cavitation control device disposed therein. The pressure control device is in such a position on the plunger such that subsequent to the rate shaping device passing fluidly communicating with the port, the cavitation control device aligns with the port to control the pressure wave propagated through the port by the termination of rate shaping.
