DPF and NOx Filtration Begin 1 Jan 07

[rbattelle]

Last week's Automotive News has an article titled "Dodge diesels will get high-tech emission gear". Among the more interesting parts of the article is this:

Frank Klegon, the Chrysler Group's executive vice president for product development, said heavy-duty diesel Rams sold next year will have a diesel particulate filter and oxides of nitrogen absorber.



Dodge plans to make a running change during the model year. Ram diesels built before Jan. 1 will have the same emissions system as 2006 models. Starting in January, the Ram will have the new system - and probably a higher price.



The particulate filter, which contains precious metals, would likely cost an automaker $600 to $800, according to one supplier familiar with diesel truck emissions systems.

It goes on to discuss the loss of power associated with the DPF, and says Ford will move up in displacement to make up for it (6. 4L Powerstroke) while GM will offer a variable geometry turbo, new EGR, and "other enhancements".



The bottom line is that the DPF will cause a loss in power and economy, and an increase in the cost of the vehicle. Buy before 1 January if you want to get a 3rd gen!

It might be too soon to say, but this may very well be the last new diesel truck I own. With all the emmission stuff, it will be tougher to modify, more expensive to buy and maintain, and less fuel mileage. It will be harder to justify the added cost over a gasser. So, I'm gonna take care of the one I got.

restricted exhaust will cause that. . but if they use the same systems that will be on the chassis/cab version [w/6. 7L] it will be a dificult job removing them without setting codes [and of course it is illigal to tamper with federal emission equipment... ]

Why not bio?

I have read story after story and heard news that just a 20% blend of biodiesel with the new ULSD would make our CURRENT engines run cleaner than the proposed new emission standards for '07 using all the added complex systems and ULSD alone.

WHAT is the advantage of "cleaning up" emissions a little if it uses significantly more fuel to do so AND has less power, thus requiring a larger engine to do the same work?

If what I have heard/read about biodiesel is true, WHY is it not simply mandated that there be a blend of 20% bio fuel for 2007?

The real advantage I see is we can run cleaner with bio/ULSD, using CURRENT technology while exceeding '07 emission standards, PLUS all the diesel vehicles currently on the road would run cleaner as well!

The H3LL with making engines more complex, less powerful, less reliable and less fuel efficient... CLEAN UP and CHANGE the damn fuel!! Much of the cost of implimenting the new bio/ulsd fuel would be offset by less cost of un necessary emission equipment and much more improvement in emissions could be made by cleaning up our entire current diesel fleet in the US by simply adding a little clean bio fuel. PLUS our dependency on foreign and fossil oil would be reduced!

Seems like a practical, environmently friendly, cost effective solution to me! Why is nobody (corporate bigwigs, EPA, etc) pushing for something like this!?!

Unfortunately, just changing the fuel will not fix the problem. Diesels by nature make lots of NOx and particulates. This is not totally the fuel's fault.



Wait until 2010 when the next emissions regulation comes into effect. That is what everyone is really worried about in the industry. 2007 emissions regulations are much more relaxed compared to the 2010 levels.

We should have manditory B-20 in this country though. Its not a cure, but it would sure help the problem. I'd also be up for a law saying that if you don't use the diesel you're buying you can't buy one. (Head to the city and look at all the duramax's without a dent or ding in the bed. :-laf )
