I have had a trawl around the internet and had no luck, so I am asking here;
Does anyone have good pictures of the tips of the Siemens Deka 12569091 (z22se standard) fuel injectors?
I am in the midst of writing an engine model and the information I am looking for is whether or not they are single/multiple hole or pintle type injectors. I am not in a position to pull some out to look.
This info will allow me to make a better port and combustion model.
Thanks,
Photos Wanted Of Siemens Deka Z22Se Fuel Injectors.

That would be very gracious of you, if you have the time.
However I wouldn't do anything with the others, at least not for a long time.
If you are happy to create a library of photos though it would be something good for myself and hopefully others to refer to.
At the moment the model only needs the spray cone angle, or a good estimation thereof, and looking at that LSJ injector i'm goning to guess the z22se parts were also from that same period of injector development for engines with bifrucating inlet ports, so will also be 2 hole.

A few years ago i had a various bunch lying around, and created below pic.
As taking actual picture of the pinholes was a pita, i took a good look, and used paint to put them in.
This does not describe spray pattern, just the pinhole locations.

Smiley,
thank you. I can infer spray pattern from the holes.
I always believe things like this may not be of use to anyone today, but may have a value later on to someone, so it's always worth adding to 'the databank'.
Can you confirm the N/A's 2 holes are off-axis, please?
The implication of being off-axis is that some fuel is to hit the back of the valve in one port and in the other port spray over or under the valve (or more unusually on the SSR or LSR of the other port).
By no means impossible, but certainly unusual.
Whereas the Turbo, VXR and those lovely EV14s are on-axis.
I'm not familiar with 680s, but is that also a Paint anomaly, or are they really off-axis?
