(02-05-2011, 05:49 PM)Volker407 So you say prechamber atomization is better altough common rail has higher injection pressure (3-4 times higher than our OM61Xs got) and can superheat through pre-injectionsYes. IDI injects and vaporizes all the fuel at the same time. Common rail still has separate injections which means the fuel still has less time "in heat".

(02-05-2011, 11:18 AM)OM616 Implying that the members that posted information that you disagree with are liars is nothing but confrontational. If we can not trust what a member says, then what is the point. I mean heck, anyone that has any skill with a graphics program can create a dyno sheet that supports anything.
I say enough. Statements that contradict solely for the sake of contradiction are aggressive, and deter members from posting. Unless you have something relevant to "CONTRIBUTE" to a thread, don't.
While this is very true, I recommend everyone stay on topic here.
What I think would prove to be beneficial here is some simple testing. Why doesn't someone rig up a testing station? Lets stop talking theoretical and half assed tests, lets start talking scientific experimentation. I would think a pop tester rigged with some prechambers that are mounted into a jar that is similar in size to that of a piston would provide some interesting results. Video record the differences.
This would be a real contribution that would far surpass anything that has been contributed in this thread so far. Jeemu has more power without fully knowing whats going on. I have a half cocked theory that more holes would be better. Forced thinks its a bad idea period.
Less talk more walk here people. The point of this board is to do more than the others.

I normally use the same uphill, try to test during same temperature and humidity. and for example use third gear and time acceleration from 2000-5000rpm with WOT. Not perfect but it will tell you if the engine has more power.
I hope someone will do that(I can't, we have ice on the roads now) and tell us about it. We will take your word for it(well most of us
) when you tell us if it helped or not
Not trying to be "negative", bu I can't see how this test will provide any useful information. You will need to create the same conditions you have during compression and combustion. The only way to do that(for people with normal equipment) is to use an engine in a car. If you don't have access to a dyno, you can do a road test.

(02-06-2011, 03:05 PM)erling66 Not trying to be "negative", bu I can't see how this test will provide any useful information.If you were testing for flame front yes. I think just seeing how the fuel mists and is dispersed would be very interesting. I believe that FI is right about Jeemu's bigger holes, that Jeemu is wasting fuel as it is being sprayed on the piston and walls and not misting in the middle. There is no doubt in my mind he is seeing more power from more fuel but I think more holes are the solution not bigger ones.
Somewhere I read a detailed thread/doc on the injectors, the angle of injection, the rotation of the pintles etc and the specific reasons they were changed. One of the items the thread/doc impressed was that fuel on the cylinder walls and piston head is essentially wasted. Even without firing the fuel in my suggested test you should be able to clearly see the difference. A simple example of my idea is the garden hose sprayer. One jet, lots of pressure. 6 jets, a shower. 32 jets, a fine mist. We definetely want a fine mist.
An additional problem to my idea is the physical integrity of the pc itself, which is where Jeemu's solution *might* be the only correct one.
If I had a pop tester this video would already be shot

You can rent it on PeachParts, or buy it from MercedesSource. You need a slide-hammer with a special attachment to pull the pre-chamber, and a separate tool to remove and re-torque the locking collar that holds it in. Maybe you can copy the design from the MercedesSource photos?

(02-07-2011, 03:56 PM)ForcedInduction Pulling the prechamber is the easiest part, its removing and torquing the collars without fucking up the slots thats difficult.
With the right tool its a cinch. I ruined three sockets making a home made tool. The secret is the angle of the dog ears and the ability to lock them in.

One thing I have access to is both chassis & engine dynos so there may be some testing on hot bulb changes going on in the I.E. for the SoCal crew, keep this thread going!
Man this is a great site, I remember about a year ago there was some heated discussion about pc's but not like this, imho I think there can be some tunning advantages screwing around with the pc and I agree the best way to find clues to this question is on the dyno.

I'll donate a set of five pre-cups from a 1981 SD to whoevers going to the dyno. Whoever wants them, just PM me.
It would be nice to see the graphs from a variety of different sized precups and just how the hp/torque curves increase or decrease or move around.
Now that I think about it, I have two sets of five I'll donate.

1981 300SD...Too much propane = bent rods. Junked
1980 240D...Body fell off. Saved drivetrain and junked

One other measurement that is critical is the dimension that the prechamber tip protrudes out from the head.

Not at all. The only thing you need to consider is if the head has been machined. If it has, you use a thicker seal ring.

You can get the ring collar tool at pelicanparts the cheapest. I have one you can borrow for shipping costs both ways. I also have a 22mmx1 ring you can borrow. The ring, a washer, bolt and a slide hammer will pull em out. You will need replacement shims but they are cheap.
