Sure can. First tho, have a read here: https://www.manilatimes.net/2016/07/...4UQlY-ORb7k4NY

The spray angle of your injector nozzles differ. The "0" in "NP-DN0PDN112" corresponds to the spray angle. That is the nozzle angle that I believe corresponded to the ford and '90 4d56 rectangular pre cup I have. These motors evolved over time and as you mention there are recessed valve, flush valve, but also oval (d shape?) and square pre-cups. you'll find 0, 10, and 15 degree nozzles all in application to the 4d56 if you search the interwebs.
A diesel shop sold a friend with a fordubishi 4d55 np-dn15pd6 Denso or some brand nozzles for his zexel pump. I was curious right off the bat why it was a Denso injector nozzle number on the bill sheet. He had brought them a spare pump to rebuild and if it was from another application they could have pulled a nozzle specification for that pump build from a database such as this: https://fuel-inject.com/injection/ze...ch.9460610423/
And cross referenced with Denso or something else.
And told him those are the correct nozzles.
But they may not be, even tho the engine starts and runs "good". But for how long? The wide spray in a narrow precup would concentrate more heat in the pre chamber. More bad because he didn't put the nozzle tip seals in when he installed them. And, they may be nozzles of uncertain quality.
I'm trying to get him sorted out as I do the same for me.
Hope this brings you a bit further along.
If you put your pump zexel number in a search engine, you'll find some info at fuel-inject.com. It's pretty amazing. Still have the old ram pump:?
