Hello Stef!

In AFN nozzles, the first stage has an opening pressure of 190 bar, and the main stage has an opening pressure of 300 bar.
I hope I was able to help you.

Regards,
Alex.

hello
Thank you very much for your reply.
I only don't understand one thing: people often say in this forum that these nozzles cannot be stolen.
The problem also exists with Toyota Land Cruisers, and it's not a problem to adjust the two-stage injectors.

best regards, stef

Hello Stef!

The main problem is primarily related to adjusting the main settings.
The opening pressure of the pre-chamber can be checked with very simple testing equipment. In principle, all you need for adjustment are the shims (spacers) that fit the nozzle holder, and ideally some experience, so that you don't have to disassemble the nozzle holder combination 10 times .
For the upper grades, verifying the opening pressure is considerably more challenging, as the testing equipment must be capable of generating and delivering the high pressure required.
Mechanically, disassembling, adjusting, and reassembling the DHKs should not be a major problem if you have the appropriate tools.

Alex.
