<p>A fuel injector for delivering fuel to a combustion chamber having a chamber ceiling, the fuel injector having a primary axis and able to control fuel delivery through a first outlet opening or together through both the first outlet opening and a second outlet opening. The first and second outlet openings are oriented such that, in use, when fuel delivery is permitted through only the first outlet opening, a first spray formation reaches a first target distance below the chamber ceiling at a radial distance from the primary axis. When fuel delivery is permitted through both openings together, respective first and second spray formations merge externally of the injector so as to give rise to a combined spray formation reaching second target distance below the chamber ceiling at the radial distance from the primary nozzle axis, wherein the second target distance is larger than the first target distance.</p> |
