Can a Euro 930 be retrofitted?

[cstreit]

Gang,

Can a Euro 930 (82) be retrofitted with emissions equipment to pass state emissions requirements?

I'm hoping not to assist in getting a waiver...

If not, why?

If so, how?

Thanks!

Sure it can be done. But I wouldn't want to.

What smog requirements do you have up there? Visual, sniffer, both? The Euro can be tuned to pass the sniffer. The visual will cost you a grand in used parts and at least 35hp.

If this becomes an unfortunate reality for you I have all the parts you need. Or - you could just move a few miles south (my vote).

[cstreit]

Rarly,

THere is no visual if you pass...

SO... How do you pass?

[RarlyL8]

Lean it out.

I don't know what CO target you would need, <1.5 I would think. Find out the requirements for CO, NOx, and HC. You can then pinpoint a spot on the curves for these items and tune accordingly.
(Look at me giving advice when my own car doesn't run right yet).

[cstreit]

THe real issue is that emissions are way off across the board.

HC standard is 2PPM, mine is 7.16
CO is 60PPM, mine is 218

In fact, the CO was so bad, it didn't even show up on the printout...

[cstreit]

So what I need help with are the reasons that a Euro 930 CAN'T be retrofitted!

Can anyone help?

Well you can always dilute gasoline with alcohol...people usually do that here in sweden when their car isn't going trough... :-)

You'll get much lower CO then...

Fine-tuning of mixture and ignition-timing together with cleaner fuel will certainly get it trough...

Funny thing is that my stock euro 930 get's 0.1% CO @ idle ,and 4.5% is max allowed

[john walker's workshop]

CO is in %, HC is in PPM. so what are your readings again?

[cstreit]

My readings are Hydrocarbons 7.16 (GPM)
and CO 218.6 (GPM)
CO2 is 400.3

THe CO is off the charts!

[john walker's workshop]

here in washington, we're not familiar with the GPM thing. (grams per what?). we still do percentage. did the tech try to turn down the mixture with an allen wrench when it was on his gas analyzer? high HCs are often just a byproduct of high CO.

[beepbeep]

CO is notoriously unstable on theese cars...when i smoged my car with semi-warm engine it showed 5% CO = too much...

I sent it to the mech (for some other reasons ) and asked them to adjust CO, he told me "there was nothing wrong with CO, just warm up the engine..."

So i drove like a idot before smog check and voilá: 0.1% CO ...

on the other hand, low CO means lean mixture, wich means high combustion temps, which means high NOx , but i doubt they check NOx on our cars.

Here they only worry about CO at idle...i bet my car spews death as soon as i step on the accellerator

[cstreit]

They check the car on a dyno, CO and Hydrocarbons. I had taken the car for a 20 minute drive on the highway prior to the test. It was warm.

I think part of the issue is that the tester was lugging the motor, adding lots of unburned fuel....

SO... What I have to do is get a waiver, to do that, I need to

1) Prove the car was legally imported. (I have that documentation)
2) Document that the car is NOT able to be retrofitted ...(THis is what i need help with)
3) Make sure on the retest the car shows "SOME" improvement in emissions.

Beg and plead

[RarlyL8]

I don't know how much this will help your case, but just HOW FAR do you go before you can claim "unable to retrofit"?
Anything can be done.
In this specific case the retrofit IS NOT a bolt on. The reason is the air injectors that screw into the heads. New heads or machine work would be required to use the stock system.

[cstreit]

Well that's just the thing:

If I can show that it is not REASONABLE to retrofit the car (for instance, air injectors requiring head modifications) then this adds to my case of getting a waiver...

So there are a few things that should help

1) There is no oxygen sensor, right? No system to handle it.
2) No air injection on heads or facilities for air pumps
3) Catalytic converters, did the 82 930 have them?

[dean]

Go to the dealer and get the list prices for all the parts that you would need to retrofit. For example I think the turbo inlet pipe lists for $2200 or so. That should help your case. Then lean out the mixture alittle before retest.
Good luck

Euro 930 all have air pumps and air injection as stock, of course, most of them don't work or have been removed. Refitting the parts that were there in the first place isn't going to be difficult.
German versions were available with a catalyst.

Your local technician should be able to "adjust" the engine to pass any smog test.
If the CO is off the charts there is SOMETHING WRONG with the engine.
When I lived in Europe, we usually set 930 at about
3 - 5% CO with the air pump disconnected. The pump drops the CO about 1 - 2% The HC and CO2 readings should stabilise to normal.

Hmmm... I wonder if there's a place that I can borrow a CO tester for a few days...
