Has WI come to a end of a era for deisels?

A month ago I had the privilage to attend a couple of new model engine seminars/classes. The big topic this year is emissions. Go figure.
Anyone who has been in traffic behind a 1976 Mack knows the soot these monsters blech. By 2010 the emissions coming out of these creatures will be cleaner than what goes in. New fuel, new federal emission standards, new spot testing for all deisel vehicils not just commercial tagged class 1's, and a no BS policy of reinforcment with big fines.
Point being WI is used widly in big ass in-line turbo charged 6's and supercharged 8's alike as a means of keeping a clean burn and lower EGT's. With the new generation of deisel engines any enemy of high EGT's is a enemy of emissions.
It's getting wierd again, just like it did for the gas engine in the 80's

you know that the average diesel has over 20,000psi at the injectors!!!!

I hope not, the diesel market is going crazy, has been for the last 2 years. We had a customer gain 205 lbs tq on his 99 F350 with our dual pump smart injection kit, pretty crazy stuff.

I always thought diesels were emissions exempt? Maybe im just crazy or maybe that was just in CALI or maybe I just need sleep.

The cummins M80 They had could develope over 56000 psi in the feed rail. I've ben workng with the IH DT466E's for years now and I thought those where getting a bit over board. The new Mercedes engine in the frieghtliner our new engine of choice.

No more mufflers. What looks like a muffler is really a catyletic converter. They use high EGT's, a burst of compressed air and a shot of fuel to burn off all the particulates caught up in the cat. Yup. The muffler now has it's own fuel injector. If EGT's are not high enough the clean burn cycle will never happen. At that point the engine de-rates for a few hours. After that and a few warning lights it just shuts down. Then I get to come out with my lap-top and force a cycle to run. Sounds like a lot of $$$.
These cat's also have to be replaced every 5 years or so depending on the fuel and driving conditions. So it's a $5000 muffler job.
You can see where WI might benifit one end and hurt another. Guess one would have to figure out what is more cost effective.
