I have not done much research in this but can tell you that urea is a commonly used fertilizer. In dry form it is 46% nitrogen, and is available in liquid form with 32% and 28% nitrogen, mixed with water to create these solutions. I believe the fertilizer is similar to what is being used, but like I said, I have not done much research in it. A quick google search told me that def is prepared by dissolving solid high purity urea in deionized water to create a 32.5% solution.

DEF is one route for making cleaner diesels, but it's not the only one.

Right now, Cummins, BMW and Volkswagen/Audi diesels don't use it. Mercedes uses something called 'BlueTec', which is fundamentally the same.

By and large, smaller diesels (3L and less) can be made emissions-ready without using urea injection. It's kind of a shortcut, in that it's easier to take a non-compliant engine and engineer it for urea than it is to design a clean engine from the ground up.

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?
VW 4banger diesel swap can you say torque and Gas savings?

some people have done diesel swaps in wranglers but it was ranked as a top overrated engine swao due to the complexity, weight,

i was very interested in the jeep grand cherokee CRD diesel but theres not many out there

due to gas mileage and the upcoming fuel spikes i will be going to a duramax

The problem with a lot of diesel swaps in Wranglers is that the ones most people use, Cummins 4BTs, are too powerful for a Wrangler and will never get to a good operating temperature, unless you're really hammering it.

Hopefully Chrysler's parent, Fiat, will see the need to eatablish a diesel option for the wrangler here in the states. I'll be the first at my local dealer to order one. Until then, I'm running VW diesels in all my vehicles...

It will never happen. We can't get a diesel ... anything over here. Just a few overpriced, overcomplicated pickups with a lot of hype behind them.

Big brother's "Green" people division hates diesel. And ruins it too by making it so complicated that none of the companes even want to think about bringing a diesel or a clean diesel over here.

Expecting Chrysler, who only took 4 years to get rid of the anemic 3.8 engine in the wrangler, to put a diesel in? Not going to happen. The only way Fiat would do it is if they could see it strengthening the Jeep name. That's about the only worth Chrysler has today.

u would think chrysler,well not sure of fiat's capacity,but you would think they would be developing a hybrid,albeit i'm far from an expert on chrysler concepts,but their the last of the big three who has no current hybrid's in production,hybrid's would probably increase their sales considerably,and leave them room to venture on more unconventional ideas.

I was thinking of maybe buying a 2012 Jeep JK Diesel in Europe and having it shipped to Canada. It would be extra $$$$ but at least I would have one if it could pass inspection.... Just an idea for the moment as I will be ready to buy once the 2012 are on the market....

What would be the point of making an efficient, powerful engine that will literally last the lifetime of the owner?

Because there is VERY little demand. Hybrids may be hyped up by the greenie crowd, but theyre the only ones that buy them. Its such a tiny market and in reality, the cost and complexity dont result in any $$ savings. People that buy trucks and 4x4s want power, capability, longevity, and the ability to upgrade a vehicle. Try doing a lift and bigger tires on a hybrid. It would probably fry the computer trying to compensate for any of this. Oh and forget about any kind of engine mods. Leave the hybrids to Toyota. Hell, even in tree hugger infested Portland, the used car lots are packed full of these things that no one wants.

Diesel Has its Place in a Jeep

I'm all for diesel... its in my user name!

I don't care what the anti-diesel crowd has said in this post, diesel engines are a viable option for the future of America. New diesels are more powerful then they have ever been before. Furthermore, they are clean and the emission systems are rapidly changing to make the system overall more efficient. The torque, the mileage, and the longevity are all pros of a diesel engine. However on the other hand, the weight, the cost, and the platforms these vehicles can fit in are certainly the cons of a diesel platform at this time.

Now with that being said, the 2016 emission standards are going to push the modern automobile into its next phase. All types of engines produced today are going to need to be reinvented or scraped. Diesels put out far less pollutants across the board, minus nitrogen oxide emissions. What is even better is that they can run on biodiesel! You can make biodiesel from numerous food and non-food based sources. From waste veggie oil, to soybeans, and the rapeseed plant. Biodiesel can be made today,tomorrow, and the next day after that... all from renewable resources! Not to mention the future of most second generation fuels will certainly come online within the next decade.

Jeeps are durable vehicles and I'm sure fiat has wranglers equipped with diesels already in them. VM Motori motors (think Jeep Liberty CRD diesel motor company) currently power the European 2011 Grand Cherokee. There is only a matter of time before the vehicles we build in America (sent over with diesels engines) are simply sold in America.

Time will tell but I know it will happen, lets just wait and see. In the meantime, pick up diesel power magazine. There is always articles regarding future diesel motors in American vehicles.

Well it's a fact that Jeep Diesels are available in Europe, but because of emissions they have yet to be certified here, requiring additional engineering. A diesel in a Wrangler will happen at some point, and I am willing to wait. I have refused to buy a new solely due to the lack of a diesel option. Used and aftermarket has been my solution. The 3.0 CRD in '06 for the GC and Liberty almost made it to the Wrangler, but fell short because of the now well known financial problems of that period that played through to a the bailout and ultimate majority sale to Fiat.

And yes, Diesel Power magazine is a must read for anyone even remotely interested in owning a diesel. While they are mostly full-size truck orientated, the editors have been expanding coverage to more diesel platforms both larger and smaller. I am a dedicated subscriber since the magazine's inception and occasionally send in submissions to their reader rides (My '06 Super Duty LWB Crew made it in a few years ago). Oh and check out the bottom right of page 21 of the Feb 2011 issue titled "New Diesels for Jeeps". It mentions the 2.8L being put into the Wrangler and Wrangler Unlimited, but "Only outside of North America".

Let's go Fiat, get a Diesel Wrangler for North America already!. It's long overdue!

Here in France, the 2.8VM diesel is the common motor in the Wrangler (fuel consumption is better), the V6 model is much more expensive (and higher consumption ) and could only be buy in JEEP dealer on special purchase order . Generally in Europe (except Switzerland) price of gasoline (for V6) is also more expensive than fuel due to the fact that nearly European trucks have diesel. More the torque is much better in the diesel than in V6.
But in 2014 all European Diesel in new cars must be much cleaner (specially regarding Nox) i think we will have similar emissions as in US therefore JEEP will have to put a much cleaner Diesel in JEEP models or a much better V6 ( lower consumption).
I assume that FIAT will put in JEEP a cleaner Diesel in this case they will certainly be able to pass also American emissions . I hope it will be a reliable diesel .
