Other people can answer this better than I, but you'd probably be surprised how much $$$ they are spending on research to get these things to pass the emissions. There lies the problem. The emissions were better before the aggressive and shit EGR systems. And thus better before DEF.So you plan to reduce emissions by forcing everyone to add another tank, pump, hose, chamber in the exhaust, and fluid to add to the vehicle. They're not forcing anyone to add anything. All they did was set the maximum level of emissions that can come out the tailpipe. How the manufacturers actually go about doing that is up to them. #1 thank you for letting me know. I thought DEF was a government requirement. The fleet workers I k.ow use it and cannot imagine it is the cheepest way for them to continue passing the tests. #2 it still causes more harm than good in the total cycle. More harm, but higher profits for all involved.

Nine times out of ten the solution they go with is the simple "band-aid" fix.

Oh I'm sure they spent a pretty penny. Thing is, they probably came up with several viable solutions, then presented these solutions to management. Management then runs cost-benefit analysis on each of the proposed solutions, and chooses the one that will benefit the company the most.

So, instead of spending R&D to figure out a way for their engines to run efficiently, they instead slap on some cheap & quick fixes.

To compensate for the all this damn soot, some of the newer engines run leaner to ensure a more complete combustion. Uh oh, all that extra oxygen ramps up NOx emissions! Shit! What do we do now!? Diesel exhaust fluid is injected into the exhaust system. It vaporizes and combines with the exhaust gases to form compounds which can be broken down by the catalytic converter.

Oh no, far from it. I simply don't care for the stupid ass penny pinching measures the OEM's are using. The EGR system recirculates a portion of an engine's exhaust gas back to the engine cylinders to reduce NOx emissions. Adding the exhaust gases in a diesel enigne reduces the specific heat ratio of the combustion gases in the power stroke, which reduces the amount of power that can be extracted by the piston. It also tends to reduce the amount of fuel burned in the power stroke, resulting in incomplete combustion, which increases soot. Soot, the black smoke coming out of the tailpipe, is that partially burnt fuel. That's literally money shooting out the damn tailpipe; you're burning money! Now what?! That's where the DPF comes in. All it does is filter the soot so it doesn't shoot out the tailpipe. Over time it clogs up, restricting exhaust flow, robbing more power. Then it uses yet again more fuel to burn the built up partially burned fuel (soot) in the DPF during the regen cycle. BRILLIANT!

Used to happen all the time in Texas. A lot of the highways had two speed limits: one for day, usually 65-70, and one for night: usually 55-65. At dusk the highways basically turned into a giant speed trap.

of course, I never let my vehicle drop below a quarter tank anyway because I'm paranoid about starving the fuel pump

because of how much fuel it dumps into the DPF during a regen cycle

I don't remember but I think it's Chevrolet's trucks that are programmed to not run a regen cycle if you get below 1/4 of a tank

The real kick in the nuts is the Diesel Particulate Filter, or DPF. When it gets "full", the computer dumps a bunch of fuel into it, and burns the built up soot. It's called the regeneration, or regen, cycle. Because of the large volume of fuel it dumps into the DPF during a regen cycle, fuel economy plummets.

They're basically patching the engines with "band-aid"s to meet federal emissions standards, because it's the cheapest route.

Less problems in total, far greater cost per failure. I agree 200% I was reading something about the Ford 6.4l and it seems that if you don't drive it long distances that you'll have problems with this exhaust filter thing not being able to burn off the soot and then all this talk about exhaust fluid and adding shit in your fuel and different blends of fuel for the winter and the list goes on. WTF is exhaust fluid and why the hell would you build an engine that doesn't do well in town or idle. It sounds like a damn drag engine not being able to drive in town and not being able to sit at idle for long. I don't know if all or this is just a bad Ford design or if its all manufacturers. I've always heard diesels were a lot more maintenance free than a gas engine, but after all the had things I read it sounds like somebody needs to get their head out of their ass! Lol Check out this thread out; it shows the emissions systems on the newer Cummins. Chevrolet and Ford use similar systems.

http://www.theatlanticwire.com/global/2013/09/theres-clown-terrorizing-small-british-town/69425/ This is hilarious. Clowns are no laughing matter. Seriously. NSFW People freak out at the haunt when the clowns come out. I saw some article the other day talking about haunts where the actors will bind and gag the guests, drool on them, jam their fingers in the guests' mouths, and other creepy shit. Some even have the actors acting out scenes of graphically violent rape. Yes those Haunts are out there, but I promise you we do not do that at Spookhaven. Oh I know you're on the up and up; I was just surprised that there were such things out there. Some people are a little...off...

Everyone will bug you about the EGR and then when you tell them it's been dealt with and tuned it will pull down apartment complexs. Great trucks. Strong engine. Really horrible EGR problem. Databoutit. So much so that Ford severed ties with International and started making the diesels for the Super Duties in house.

the 6.0 Power Strokes have big time issues with the EGR cooler
