2010 Diesel Emission Standards

There are some pretty tough new emission standards coming out in 2010 for Diesel engines. Cummins is using a technology which will inject urea into the exhaust while Detroit is using an exhaust method that puts the exhaust back into the engine as I understand it. The standards are stingent enough that Cat has ceased making over the road Diesel engines for 2010. My question is, do you think someone should buy now to avoid the new requirements, or don't worry about it, or wait a few years until the bugs are ironed out of the new engines?

The GM Duramax is also going to the urea injection system. The system works so well, in some cities the air coming out of the engine is cleaner than the air going in.

Having said that...if I had a choice I would buy now to avoid having to fill the urea tank as needed.

I understand new BMW car diesels already have the urea injection

It sounds like the 2009 diesels are getting terrible fuel mileage load or unloaded so hopefully this doesn't make it worse. I have been wondering about buying a low mileage '06 or '07 due to this.

Don't forget that there 2 versions of what is being talked about here.....

The OP is talking motorhome diesel engines, (it is posted in the MOTORHOME forum) which are different from the diesels in our pick up trucks. The current Cummins motor in pickups is already compliant with the 2010 standards, WITHOUT a urea tank. The Duramax and Ford diesels will use urea in the 2010 pickup engines.

I am not up to date on the motorhome diesels, but I did hear that CAT was backing out of them.

yep
the 6.4 cummins by virture of its egr is 2010 legal
however, dont look for it to be around in that config very long
egr has been problematic for a all three and thats the other reason they are going with urea.

the urea should by design regain some mpg and not reduce HP
fords new pickup engine is stated as going 7500 miles from one urea tank fill
i would assume all will be close to that.
cat...is a killer they gave up the ghost for the 2010 over the road engine....however i would expect them to be back, to big of a market to not re-look at the engineering

By the time you figure the extra cost of the diesel, the extra cost of diesel fuel, the cost to fill the urea, the V-10 gasser may be a viable alternative; at least for some. Depends on how much you have to pull and how far you have to pull. No one right answer but the diesel is not necessarily a no-brainer answer for everyone.

As there is some discussion regarding gas vs. diesel, I've attached a link to a test done in 2007 comparing gas vs diesel 3/4 and 1 ton pick-up trucks...makes for interesting reading.

Appears the above link isn't working. Try cutting and pasting.

Wow. If any one is interested, I still have my very low milage, loaded 2005 GMC 2500 Duromax crew cab for sale from my 5th wheel days. Now I'm glad we went with the Ford V-10 this time in our motor home.
