This International Standard specifies dimensional requirements for the mounting of injection nozzle holders in internal combus-tion compression-ignition (diesel) engines.
The location of the fuel inlet and leak-off connections are not defined since they vary according to the particular applica-tion.
This International Standard applies to screw-mounted injection nozzle holders, types 12, 13, 14, 15, 16, 17, 18 and 19.
Nozzle holders types 12 and 13 are used with the nozzles specified in ISO 2697; nozzle holders types 14 and 15 may also be used with these nozzles.
