I think our air is clean enough, its so much better now than it was in the 70's and 80's, I think we should just stay where we are emissions wise, and let the manufactures work on efficinecy. the ole 12 valves would pull down 20mpg with no sweet in 4x4 duallys etc. imagine if the EPA had not got invovled and with the aid of electronics where we would be now, I bet we would all see 25mpg, pretty soon we will be at half that in the same applications, I still don't understand how a less efficient diesel engine can produce less emissions even though its using a greater amout of fuel to do the same work

NO kidding. The problem is that we're burning fuel with all kinds of nastiness in it.



The emissions system on these trucks are almost like having a sewage plant in your own home. You start with dirty junk, yet you're supposed to have super clean waste output???



Diesel should be CLEAR imo. I've seen a lot of biodiesel that looks like water (only thicker).



But of course we can't get it, because that might make farmers some money instead of the oil barons.



ULSD is a step in the right direction, and I'm excited to get it.



Buyt ultimately, a super clean fuel like some GTL stuff or super-refined bio is going to be best.

This is why EXXON is now richer than WALMART!!!!!!!!!

Which is nothing new. Who do you think has been there before? What companies have been there and are always in the top competition for the forbes 500? oil and car companies. im just wondering why they are posting profits in the billions for a quarter and im paying 2. 70 for diesel this last fillup. profits. not net. none of that goes for building new infrastructure or paying salaries, those bills are worked out in company operating costs. profit is shareholder money. at least thats what the word profit means to me.

This is exactly what I don't understand either, makes absolutely no sense to have a more efficient diesel that gets crap fuel mileage.

Just like being a Racist or Pedophile, nobody in the EPA or Washington for that matter wants to be associated with lowering "pollution" standards. While the Diesel engine runs much lower CO2 output than a gas engine with comparable output, they do put out more particulates or soot.

In Europe they have recognized that there is a benefit to trading one type of pollution for another if you end up with less net pollution in the end. In the US, they do not want to be seen as soft on soot, so the the diesel does not get a break on the amount of particulates they emit.

You are correct on one point, they lower MPG means the the later model engines emit more CO2 but they have developed ways of emitting much less soot.

The 5. 9 has been around for close to 30 years and has lived in the Dodge pickup for 17 years with only incremental changes to the basic block. Ford has had between 3 to 5 major engine changes since then, depending on how you want to classify them. They will go to a new 6. 4 liter engine to meet the 2007 regulations. Ford's biggest problem. in my opinion, is they do not stick with an engine long enough to work out the bugs. GM has only been back in the diesel market for real since 2001. They have been smart enough to stick to the basic design and work towards improvement.

This is the first engine change in nearly 20 years for Dodge. Will it be as smooth as the 1989 introducton of the Cummins or as disastrous as the 2003 Ford 6. 0. All of the good armchair QBs will be able to tell you just how it went by Jan. 2010.

I don't know wha the actual #'s are, but here's an example.



Let's say pickup A gets 20mpg and is 97% efficient. Pickup B gets 10mpg and is 99% efficient. Which one produces less total emissions?



Pickup A would have to get 30mpg to get to the same level of emissions. And since we're the ones paying for the fuel, why should they (gov't) care as long as the emissions are met.

I think our air is clean enough, its so much better now than it was in the 70's and 80's,

maybe so, but the air in the northeast is terrible due to the dense population and the coal power plant's along the ohio river. We have acid rain which is killing forest and sterilizing ponds and lakes all the way to maine. Just because we can't see it, doesn't mean it isn't there. I think we need to bring on the mag hilev, but that's another debate

 

[EMorad]

Maybe DC can just sell the truck with a engine delete ... then install "old" used 12 and 24 valve engins in there.

LMAO @ engine delete

 

[MMeier]

So, how are they going to implement the urea injection? Are we going to have to pull over to pee in a separate tank?



jh

With some of the stuff I used to drink in my younger days, that could be one explosive mixture!!!

LMAO @ engine delete

This is something Ford should think about :-laf

I won't buy an other dodge untill they do come out with that 4500. If there isn't one out by 2008, I am taking my cummins and going f450 shopping. Anyone want a new powerstroke engine for free



My other option is to build my own truck over the next couple of years. Something along the lines of a 3-5 tonne chassis, remove the axles and replace with 2. 5tonne Rockwells with disc brakes and independant lockers, and international (I think they use spicer?) transmission and transfer case mounted to a slightly turned-up Cummins 5. 9B series (with the super reliable P7100 injection pump of course), and for tires instead of going with duals, running just 4 of those "super singles", the kind you see on many off-road logging trucks on their steer axle. The suspension would be changed to military style coils, or, multi stage leaf packs, whatever was easier for the spring shop. I figure I could put this all together for a little under $40,000 which would probably save me close to $20-30,000 over something like a unimog. Inspection might be a pain though, I'm not sure about how that would go b/c it would be a homebuilt commercial vehicle, which they might not like very much Where there is a will, there will always be a way.
