These arrived in a shipment from Germany.
They are new Bosch pintal assemblies.

Due to the nature of the cargo I think they may be Mercedes injectors for
a OM352(a) type engine.

The boxes are Bosch. Part # DN 8 S 2.
There are about 75 pintals in all.

I have the paper manual for the OM 352/a and OM 355/5 engines from Mercedes but there is no mention of the Bosch injector part number....only Mercedes part #'s for repair tools.

I've searched Google but apart from test rigs, not able to identify.
Local Bosch agent not any help either.
Before I email Bosch I thought the 'collective' might know.

I tried a set in an old 240D but they smoked too much and the engine overheated (too much fuel.)

The pintal is different from the 240/300 injectors.
These are flat nosed and not cross drilled.

TIA....dk

So you've found nozzles that fit in the OM616/617 housings and fuel more heavily than stock? There might be a market for those.

In a word...NO.

I think the spray pattern is different from a prechamber injector.
On my test bench it seems to spray a wide cone spray..
The 616/7 OE's seemed a tighter cone.

I'm going to do a back to back spray check right now, and see if my observations of a few months ago where correct.


Stand by for update tonight.

Just had a thought......The controlling factor of injection quantity is the lift element in the pump, not the injector .Hmmmm.

Not entirely, the Dodge/Cummins engines pick up 20-70 hp (depending on which injectors the engine had stock) when you stick Lucas marine injectors in it. Some of what the IP sends out goes into the prechamber, some of it goes into the return line. The injector controls the amount that gets returned.

As stated before...not entirely. THe injetors can only flow SO much at so much pressure...so if you, in essence, make the flow higher then you can get more fuel in there with similar atomization, etc.

Find out anything yet?

I have a element that is leaking at the base. Is this a easy fix? What is involved? Looks like a gasket at the base where it is leaking. Is it a matter of taking off , new gasket? Or is it under pressure and I am fixing to open up a can of worms? THANKS for ALL info.
