Bosch diesel injectors

[jonfall]

Hi, clever people, can anyone tell me what the no's on an injector relate to?
ie: 0432193701
Do they signify certain parameters as do the injector pump no's?
Thanks

Its just a part number. It relates to the injector body, the nozzle and the set pressures but it isn't decipherable easily unlike the pump numbers I believe.
