Diesel in a Wrangler?

I have heard for a while that Jeep has considered putting a diesel engine in the wrangler. It has been done in Europe but will it be done in the U.S???
The only reason why I have heard that it wont be done is because of emmisions. What a horrible reason!!!
Any other plans or ideas?

well, emissions damn near killed the big three diesel manufactorers. i think the only one that actually had it in time to meet new standards was d.d. cat and cummins had to borrow technology, no i believe they had to have the gubment make d.d. giv ethem the tech just to make it. i dont know, im not in the loop anymore, but that was the last info i was gettin.

I don't think there is any reason for them (I mean I would love one) but as for them producing them the pentastar produces lots of power and gets great fuel economy (so we hear). With the power and economy of the pentastar there won't be enough diesel buyers to make the emissions hit worthwhile.

On a related note same reason we won't see a hemi, good power numbers for pentastar mean no real reson for a HEMI although Chrylser does like to shoe horn them into anything they will fit into so I guess you never know.

I really don't think it will happen in this generation of Wrangler. If it happens, 2017 or later would be more likely.

However, Allpar is reporting "Fiat diesels
will eventually power some Chrysler vehicles (possibly including Jeeps currently VM-powered), in export markets; however VM Motori continues to hold sway. The 4.5 Cummins QSB four cylinder is rumored to have high power but again, emissions are an issue for US sale. A Fiat diesel is reportedly being tested by Siemens for US certification in the 2012 Wrangler."

It really all comes down to economics. Chrysler needs money right now, they will do whatever is most profitable. New upcoming CAFE standards mean that average Chrysler MPG ratings need to increase or pay a fine. Hybrids are very expensive to engineer, so diesels could be a quick fix to avoid paying.

If they did go the diesel route, Wranglers would be a good choice since we would be more willing to buy a diesel then a Caravan or Sebring buyer. Of course, it may just be cheaper to pay the fine, or more logical to put a diesel in a higher volume model like the Ram 1500.

WOW! You guys sound like you have done your research. I had no idea about any of this. I first started thinking about it when I was watching an international jeep video from Europe somewhere. They were talking about testing out their wrangler. They mentioned that they had a diesel in it and that is how I started to think about it. I have the 4.O I6 and that is an amazing motor in my opinion and I know many others agree. I like the torque ouput on it and it is very dependable. So I know that when (if at all) there came a time to put a diesel in it, it would have to out-do the 4.0. I would definitely be willing to try it out!

A Diesel Jeep would be great, and I would venture it would sell. I guess you will not see it thanks to the big corn industry. Low sulfur clean diesel engines are a different animal compared to the old tech.

Visited with my brother in law for Christmas. He works for the Department of Agriculture. He says that farmers are complaining how fuel thirsty new farm equipment is now that they have cleaner burning diesel engines. Many say they can't afford to use new tractors but parts for the older more fuel efficient tractors are getting hard to find.
Sounds like higher food prices and more corporate farms as the individual farmer can't afford to compete.

It's not going to happen. The new diesels now require D.E.F. (diesel exhaust fluid) and you have a separate tank you have to fill or else the engine cuts down to 50% power.

This stuff sells for $7.99 gallon at ford dealerships and $3.99 gallon at oreillys. We have a 2011 diesel that requires this and bought two commercial work trucks pre-2011 to avoid this extra cost and system. It adds about $3'000 to a commercial truck.

We are getting s little better fuel economy on the f-450 running the DEF fluid as it runs cleaner.

Most auto parts stores think DEF fluid is some type of joke like blinker fluid until you insist and they look it up.

I don't see this fitting into a jeep as the canisters are pretty big and the extra tank to hold the def fluid, i would love a diesel jeep but our emissions laws are going to prevent it.

Correct me if I'm wrong, but I think the Bluetech systems use urea before the exhaust. Also, I think VW passes NOx emissions w/o any urea. Finally, don't count it out for a Jeep because of packaging. A F-450 will require a lot more urea than a Jeep. It's a smaller vehicle with a smaller engine, and can use a smaller canister.

From what I understand urea and DEF fluid are the same thing. I would love a diesel Jk and would spend the extra $6-7 it would probably cost.

We have several ford 7.3l with 300,000 plus getting 18+ per gallon. Hated diesels before I started driving them and wife's next suv will have a diesel.

Yep, it's just a chemical that reacts and reduces NOx emissions. DEF might be ammonia, I'm not sure. Either way, it's usually injected in the SCR cone.

If it's ammonia:
4NO + 4NH3 + 3O2 → 4N2 + 6H2O

2NO2 + 4NH3 + O2 → 3N2 + 6H2O

NO + NO2 + 2NH3 → 2N2 + 3H2O

otherwise if it's urea:
4NO + 2(NH2)2CO + O2 → 4N2 + 4H2O + 2CO2

So, the NOx is converted to N2 and H20

the diesel pee is just a bandaid that the mans. had to use to pass emissions. as soon as something better comes along, def will be gone. its the fuel injection/death of the carburator all over again. only you older gents/gals will remember that. i thinks the gubment is being a little to picky aboot requirements. as for the the corn industry trying to knock down the diesels, why would they? can you not make fuel from corn? the answer is yes. they are already. and they make ethonal too. and to the naysayers who say that wvo or whatever form youre using is bad for the inj. system, well leave it to the motorheads to find a cure. we wouldnt be where we are now if some knucklehead said"hey if i do this, i'll go faster..." dont worry the fuel industry will be getting thiers no matter what the fuel is. diesels put out less dangerous emissions than gas motors. remember, diesel is/was meant to be a fuel, whereas gasoline, also known as benzine in some countries, is a solvent. diesels get their bad rap because back before "clean diesels" all that black smoke disgusted them, and it was all downhill from there. now its these dinks that go around "rollin coal". not all that bad for competitions, but bad for the rest of us.

I have owned many diesels, and currently own a 2500HD Duramax truck and a 2010 VW TDI. I am a huge disel fan, and would love to see a diesel option Wrangler. My wifes TDI VW gets 35-50 MPG depending on the type of driving we are doing, and with the turbo it has plenty of power (don't have to put additives in a seperate tank either).

I don't understand why battery hybrids are so popular when you can get a modern turbo diesel to get the same MPG without the problem down the road of having to replace the batteries.

I also could never go back to a gas truck after having diesels the past 13 years. My Duramax tows like a mother, and gets decent mielage as well. Having that torque in a wrangler would be nice.

Cummins also makes a diesel, they put it in the RAM, and it doesn't need DEF...by the way, my friends Duramax only need DEF fill up every 5K miles...or so he says...
