The first letter indicates where the nozzle was made, or in some cases where the design responsibility lies; eg. B = Britain (Lucas-CAV), R = France (Roto-Diesel) etc. D = Nozzle (or Deuchland for Bosch?) [BD]L = Short stem nozzle (Hole type) [BD]LL = Long stem nozzle (Hole type) [BD]N = Pintle Nozzle [BDN]0 = Spray cone Angle [BDN0]S = 6 mm nozzle needle diameter [BDN0S]D = Delay type nozzle (with obdurator) [BDN0S]273 = Unique Identifier (special features) These include pintle profile (converging/diverging), flow lift curve details, anti-coking flats etc. This number simply increments as a new design requirement is requested. |
