Diesels have 2 more dangerous emissions, Nox and soot. The DPF resolves the soot problem, and the urea will reduce the Nox problem. Problem is, IMHO that the urea will reduce combustion temps and cause the regen cycle to drag on for longer yet, as well as the pain of extra maintenance associated with urea, it gets -40 here and urea wont be flowing to quickly.......do you think people will spend money fixing or upgrading the urea system, or mod their truck and rid it of all the emissions BS????
I dont mean to be nagative here, but it just seems that this is where its going...
Despite the need for a urea solution, I think SCR technology has some big plus's.
SCR is an exhaust treatment, removing NOx gases which is the big issue/hurdle for the engine manufacturers now.
By cleaning it up post combustion, we can concentrate on optimizing combustion. Improving power, economy, hotter exhaust, less particulates(soot), less or no active regens for the DPF. All these big positives that help every aspect except NOx output. So SCR only has to clean up the NOx. Everything else can be "tuned" out.
Therefore we could expect better fuel economy, good power, without the problems associated with EGR valves and coolers. I'm for it!
I notice a lot of people who seem to have been brainwashed by all this. Go ahead and spend your money. There is no reason Ford, CAT, International or anyone else would need to add stuff to fuel if they built an engine that would burn fuel properly. I know, I'll get reamed by that statement but I believe diesels don't pollute at the level gas burners do.
It will never end as long as anyone builds engines.
Someone is alway's going to come up with some law, excuse or something the thing causes. Why don't they make airplanes run catylitic converters, make them quit leaving contrails acrosss the sky. We all know they just say it's vapor but its probably smoke. In conclusion, our horses have to wear diapers because they pollute and I hear California is passing a law that all diesels have to wear them.
That's just it though. Diesel fuel burnt properly will burn very cleanly and efficiently. But to do that requires burning at very high temperatures. Unfortunately, a by-product of any cumbustion at high temperature is the formation of NOx.
It's not just a diesel thing either. Petrol engines could be made to run on leaner fuel mixtures (and result in better economy), only that leaner means hotter burn and more NOx. So we've been dumping excess fuel through our petrol engines all this time just to reduce NOx and satisfy EPA and greenies.
That's why I'd be supporting SCR systems if I were you. Engines burning the fuel properly to start with and clean up the exhaust afterwards, rather than compromise the combustion and reduce efficiencies. Makes sense to me.

Diesels do put out less emissions, but the one thing they do produce a lot of, NOx, is a biggie for treehuggers. And yes, that trail you see behind jets IS water vapor. They do leave emissions, but they aren't what you're seeing.

The 6.7 is already out? I wish International would make the good ole 7.3 again that was the best diesel ever made! Mine has 565000km (371000miles) on it and still runnin' strong
My experince with breaking in new motors is don't use a high quality oil..... The are too slippery and it takes the rings a long time to seat. When we rebuild our diesel tractor engines we have to buy cheap non dertergent oil. Used our normal high quality years ago on a new motor and 600 hrs. later it still hadn't seated and burned oil, john deere dealer disasembled the motor to see what was wrong, motor still had hone makings said the rings hadn't seated yet. Used cheap oil to break in motor no problem. Sounds like you may have the same problem.
well on the discussion of pollution I think were to late and a dollar sort theres just to many rigs on the roads and factories pumpin out the smog
everyone needs to just live it with you only live so long on this planet anyways
diesels safe hell it feels to ground gas go up diesel smoke goes down but but motors burning oil

I think this is a good translation, diesel emissions drop to the ground while the gas burners emissions rise to the sky but diesels are oil burners, something to that affect
by the way. i just read the new urea system will cost us less than half as much as the DPF on the new truck. The current system cost right at $2000 per truck for Ford to install on these new trucks. The 6.7 emmision stuff will be around $800

Urea Injection does not replace the DPF. You still have both.
Not true. The Urea system is being implemented to allow the diesel engine to perform at normal levels without the assosiated restrictions and added fuel consumption. As a matter of fact this system underwent a great deal of scrutiny because this will be the first emissions system that is dependent on the drivers input to keep the system operational. Since Urea is ony introduced into the exhaust stream it makes no difference to the engine if its avaliable or not. So, in order for the EPA to approve this system the automakers had to agreed to implement a governing system that would not allow a vehicle to restart once the Urea is depleted from the system.
