Dodge to offer 1/2 ton diesel truck

[owmygulay]

All of the new stuff is Fiat designed.

Yep. Just about all of it. I read today that the vm 3.0 that is going in the 2014 Grand will be getting 30mpg highway. The ram should be close to that.

Cool, but I'd much rather have a diesel Toyota Tacoma

It's a shame that it's not the same engine in the Sprinters. We have a lot of guys running those and getting 24+ mpg with a full load.

They're great until they break though. I'll see those suckers with the engine pulled out and the joke is that they're just doing an oil change.

$200 oil change.

I used to take care of one of those FedEx contractor's sprinters.

I came a signature away from buying one about a month ago. 24 MPG is awfully nice, but having access to qualified mechanics is nice too. The Chevy Cutaway gas vans and International diesels are so common anybody will work on them.

Diesel engines run at overstoichiometric air-to-fuel ratio to ensure the combustion of soot and prevent unburnt fuel from being emitted. The excess of oxygen necessarily leads to generation of nitrogen oxides (NOx), which are harmful pollutants, from the nitrogen in the air. Selective catalytic reduction is used to reduce the amount of NOx released into the air using DEF. Diesel exhaust fluid (from the DEF tank located in large trucks) is injected into the exhaust as it moves through the engine where it vaporizes and decomposes to form ammonia and carbon dioxide. With the SCR catalyst, the NOx are catalytically reduced by the ammonia (NH3) into water (H2O) and nitrogen (N2), which are both harmless and are released through the exhaust.[4]

p.s.

That's a copy/paste. I'm not nearly that smart.

thanks for taking time to find that... 

Here's a really good explanation of the stoichiometric combustion principal.
http://www.mae.ncsu.edu/eckerlin/courses/mae406/chapter3.pdf
 
I studied this as an Incinerator operator years ago.   There is never a complete burn of everything, but we're learning to be more fuel efficient while emitting less unburned dioxins to the atmosphere.  It always troubled me as to why the EPA required CAT's to be installed in consumer diesel exhaust systems, when most of us are increasing pipe diameter to get better cooling, so in effect, the cat never gets warm enough to do it's job, Yet, they don't (or didn't -they may now for all I know), require them on commercial rigs!  The urea injection is just a stop gap until we learn more about how to clean things up a bit better. I understand that the propane injection, (to cool fuel mixtures and build even more power), burns even cleaner than a post treatment urea engine.   If I'm going to pay to add a post combustion 'additive', I'd like to make more power or increase fuel economy. Not just reduce emissions.

The def fluid from what I understand only lasts about a tank full. Just another thing to add to the high cost of diesel! Another $6+/- per tank. No thanks.

Dodges will likely get topped off at each oil change interval. Don't know about the rest.

Not even close. My Duramax uses about a half gallon of DEF per tank of fuel. Thats about 10 tanks of fuel for every tank of DEF.

DEF generally adds between 2/10ths and 4/10ths of a penny per mile to the cost of operating the truck.

Just get a delete kit if your non comercial.. I'm gona run my 0305 into the ground before i buy this new crap.

[WDFW Hates ME!!!]

I drive a 17,000 pound lift truck at work. It is a Ford with the new motor. Also has the Urea injection. We put a 5 gallon jug about every oil change. It gets 10 MPG. But it is 17,000 pounds.

At home i drive an 08 mega cab with the 6.7 cummins, with the DPF delete and a 4 inch straight pipe exhaust, best mileage i ever saw was 23.5 from salt lake to boise, routinely get 22 unloaded on the highway.

I see the new half tons as a fad. What is the use of a half ton over the 3/4? The only thing that changes is the rearend and an inferior motor.
Sounds like a waste of time to me, anybody that will buy a half ton over a 3/4 doesn't really need it.

[Special T]

Make it a 4 door and its not worthless.... But you and I do real work with our trucks...

[fillthefreezer]

i would rather see a 1/4ton with a little disel that gets 30. im not selling my one ton. and i want a little crew cab that gets good mileage and makes tq. seems to be nothing in the market that suits me currently.

The other issue is it's new. With new comes a year or two of fixing and working out  the bugs. The 2nd issue is that if enough aren't sold it will be a one maybe 2 yr production.
