Abstract:
A fuel injector comprises a fuel feed arm and a fuel injector head and the fuel injector head has a fuel passage. The fuel feed arm has a fuel supply passage in fluid communication with the fuel passage in the fuel injector head. A first light guide extends through the fuel feed arm and has a distal end arranged to direct light into the fuel passage in the fuel injector head. A light source is arranged to supply light into a proximal end of the first light guide. A second light guide extends through the fuel feed arm and has a distal end arranged to receive transmitted light in the fuel passage in the fuel injector head and a light receiver is arranged to collect light at a proximal end of the second light guide.
