    Default New diesels and emissions. A bad thing?

    I see a lot of complaining on this forum about the diesel emissions requirements on new trucks and machinery. I have mixed emotions about this subject. I am by no means a tree hugger, but I read an article in Diesel Power magazine about this subject a few months ago. He said have you ever gone outside in the morning, taken a deep breath and said "the air is too clean today". This is coming from a magazine that has a lot of ads for deletes on diesel trucks. He put forth the idea maybe we shouldn't be doing all these deletes. Anybody that pays attention to this stuff also knows the government is watching this. I think Edge products got hit with a suit and settled out of court for $500,000.

    I think there are a lot of parallels between the emissions on gas engines and diesel engines. If you remember the late 70's and early 80's, these were pretty dim years for cars, and performance cars even more so. Things have progressed, we have fuel injection, computers, cats, egr etc. that have really cleaned up gas engines. I never read on this forum about people complaining about all the stuff on there gas trucks. Cars get good mileage, ride and handle well, and perform better than ever.

    In my opinion, diesel owners just need to ride this out, auto makers, tractor makers and heavy equipment makers will figure this stuff out, make things better and cleaner.

    What say all you?

    I see your point. Its a tough pill to swallow when your 10 year old truck out performs the new models.

    Problem is the EPA hopes to regulate vehicles off the road . However with enough technology and money the engines can be made to burn clean.
    Now the EPA is inventing a concern over CO2 because the manufactures managed to meet regulations on NOX, soot, HC and a NOX the EPA had planned on being impossible to achieve.
    Unlike choked 70's and 80's carbureted emission gassers. There was still computer control as a solution. There is no simple or economical updates left to make diesels run, cleaner, cheaper or better.

    Diesel being an oil by nature is heavier and more difficult to achieve a clean burn than gasoline, alcohol, LP, natural gas or hydrogen.

    I say what abou other countries and emmisons? Travel outside the US to other countries and see what they drive/sell new. Makes you wonder, I guess the air there never travel to the US.

    Agree with buickanneere.

    No one is opposed to the idea of being clean, but the way the government goes about demanding it doesn't include a lot of common sense, and you have to question their motives at times.

    Dodge Man good idea for a thread and I think your point may be valid regarding early attempts at emissions equipment on gas engines. Those were dark days (have you ever fooled with a feedback quadrajet on an 80's GM product!?).I'd never have expected the levels of performance and emissions we have today from cars. For example a new honda with a ULEV rating is something like 100 times cleaner than a previous LEV rated car, which is a matter of only a few years progress. However the huge leap forward came from developments in automotive electronics and injection systems, and I wonder if there will be a similar leap with diesel.

    The inversion in fuel pricing has killed off the major cost/efficiency incentive for diesel though, and they may never recover from that. Our company hauls with an 06 Ram 3500/6.7 cummins and its got plenty of power, but I might as well be using my gasser gmc as it costs the same when you compare fuel cost and mileage. And one was a heck of a lot more to buy and maintain than the other

    Some commercial drivers and fleet managers I've talked with claim mpg reductions, higher maintenance costs, and decreased longevity from large trucks, so perhaps there will be some lobbying from the industry to resolve some of this.

    Maybe its just where we live her in Ohio, but hot rod diesel trucks outnumber muscle cars and imports, and the kids sure like to play with the tuners. Wonder when the Fast n' Furious movies will start using Powerstrokes and Dmaxes rollin'coal instead of Hondas burning NOS

    Most really don't realize how much soot and NOx those '90's model diesels are making. Probably the only way they were allowed to do this was because, especially in the 80's/early 90's, there were so few diesel passenger cars/trucks on the road. By the late 90's it had probably went from a fraction of the trucks/cars to several percent, and much more emissions and soot.

    I am not a pollution engineer but I seem to remember that with diesels the particulate (soot) and NOx were the big offenders on these trucks. I don't know if the particulate filters and exhaust fluid will be the long-term answer. I wonder if we will have to have those on our small tractors? I have seen a lot of stuff written but I have never actually heard of a 50-HP or less tractor having the extra DPF/DEF. I don't know one single person (personally) who has a post-2007 Dodge that is happy with the truck and I know several who are unhappy with their GM/Ford (especially the 6.4 Ford).

    I do know that when I need to buy my next truck I will have to think really hard about getting a diesel, even though I really need one for my applications.

    I say it also at that time wasn't nearly as hard for the average Joe to buy a brand new car and/or fix it himself. So yes, cars have gotten better at the expense of complexity, meaning higher cost and sophisticated troubleshooting. Double edged sword I guess.

    As a disclaimer, I was not alive back then to know the truth about affordability, I am merely going off of conversations had with may parents and old timers. Of course their perspective could have changed over the years and possibly their memory isn't 100% accurate.

    The sad thing is, we cannot control what other countries do. That puts us in the "do gooder" category, but costs us a lot... more than just with automobiles, but also manufacturing. We simply can't compete with the low manufacturing cost in other countries that don't have to abide by these regulations.

    The cure can't outweigh the cost of doing nothing. To evaluate if an idea is worthy everything must be included into the mix. That includes the added cost to the end user, for a person struggling to put food on their table needs to be factored in. How much extra energy is needed. For example how much does it cost to manufacture and transport additives. Then there's the longevity of the engine. If an engine will not last as long then it could lead to vehicles getting taken off the road sooner, that of course means an increase in energy used to recycle and transport them. Finally what must be balanced is how much of an increase of one type of gas should we allow with trying to remove other types. For example to get as much SOx and NOx out of the emissions we are now emitting more CO2. Finally there's the economy, when times are good people can afford to pay more but when times are tough asking more of them never goes over well.

    We currently have the technology to make a zero emission diesel engine. It wouldn't be hard to connect a pump to the exhaust to fill gas cylinders. Once full you would just swap them out for empty ones. In the real world we know that the costs and performance hit far outweigh the advantage. It seams to me that we are at the point where the cost is just too much. That's why delete kits are so popular.
