58 MPG by 2032

[WinterDeere]

Not criticizing, I totally get it. I love old muscle cars and racing fuel. But I do understand why reducing the emissions of daily commuters is a worthwhile goal. I'd like if that could not impede the fun of enthusiasts, who make up a small part of the emissions-generating public.

Like I said before, every time I start my old diesels and they fill the barn with smoke that burns my eyes, it brings me tears of joy. LOL

Quickly watering eyes is usually a sign that you body is trying to flush some toxins or contaminants, lol. Personally I am glad my tractor has a DPF so I can keep my garage cleaner.

My '03 diesel VW Jetta could touch 58 mpg on the highway if you kept the speeds reasonable... miss that car.

Yeah, I do like that my 3033r has DPF. My old 855 used to just about choke me out of the shed if I left it running while hooking up or moving implements. The 3033r smells like roses, by comparison.

I will agree it is nonsense to stifle agricultural diesels the same as urban. Carbon is still in the emissions with DPF, only in smaller pieces. Carbon harmlessly falls to the ground eventually, is good for plants, bad for lungs and buildings.

^This!

Between the much smaller number, fewer hours of operation and widely dispersed vehicles, it made no sense to make rural tractors meet emmison standards as if they were in the city.

My body is already full of toxins after 40 years of running trucks and spraying the dump boxes with diesel fuel in the wind every day loading asphalt.

And tearing strips of real asbestos my dad brought home to his welding shop from the steel mill, and lining the doors of the all the wood stoves he produced when I was 8 years old.
According to all the attorney commercials I see on American TV I should be dead by now, LOL Either that or I should have sued my father, LOL

The carbon is still there, just small enough not to form soot.

"The" carbon? That implies a DPF does reduce carbon emissions at all, but we know they do.

"DPFs verified by EPA and CARB are typically effective at reducing emissions of PM by 85 to 90 percent or more. EPA’s Verified Technology List also shows that certain DPFs reduce emissions of hydrocarbons and CO by 70 to 90 percent."

PM or particulate matter is defined as being larger than a certain size. The DPF only re-combusts the big chunks of C2 into smaller chunks. And some becomes CO2 but there isn't any oxygen added to the regeneration process but that in the fuel.

Think man. Carbon. A nuclear reaction is required to convert carbon to anything else. Carbon goes in, carbon must go out.

Okay, but you're playing fast and loose with the facts. Yes, if we pretend carbon dioxide generated during the reburn is the same as carbon of other forms going into the DPF, then we can say that ultimately the carbon all passes out. This is true.

But it is not the same, with regard to impact on the operator or the environment. The carbon is not just being broken into smaller particles, but going through a chemical change with the aid of heat. More succinctly and using the example I posted earlier, the amount of carbon put into the air I'm breathing while hooking up implements in my shed is not the same, because I don't let the thing sit and regen while I'm in the shed with it.

This isn't far from the folks that pretend EV's aren't any better for greenhouse gas generation than ICE's, "because they both ultimately use fossil fuels". Half-truths aren't full truths!

No, the large carbon flakes are harmful to your lungs while the smaller carbon "ash" (according to the PDF you cited) is not as harmful and according to the EPA is no longer a particulate.

To make CO2 there has to be 2 oxygens for every carbon. Where are you getting that? Is not in the fuel during regeneration because if the fuel had that much oxygen if sparked it would burn without air. You know, just like lithium batteries? Without stopping until it was fully combusted.

The DPF is a particulate filter. It catches big particulates and only lets pass when burned to smaller particulates. Ideally you get the DPF up to temperature working the engine hard and it keeps itself burned clean. If the DPF could always operate like this the net cost would only be the loss of HP from the diesel engine due to restriction in the exhaust. But when pressure across the DPF increases indicting it is getting stopped up, a regeneration cycle is started by adding raw fuel to the exhaust.
