Goodbye DPF and soot?

First you have not addressed the point without regulation the research into making the engines run cleaner.

Never said it hasn't, and I am not against regulation that are well thought out and not some number reached for political browny points.

Most of the time it happens is in the suburbs. A guy in a new, shinny, lifted pickup can leave the light, blowing enough black smoke that pedestrians can disappear. But the maid on her way to clean the house of the rectum that just choked the kids walking to school can get a ticket because 20 year old Toyota is smoking as she slows for the light.

Well that guy deserves a ticket just like the guy in the gas truck that clearly was blowing oil though his piston rings that I had to smell for miles down a back country road the other day. Just to make it clear, I am against rolling coal just as much as you. However, you can still modify your truck and not roll coal. With today's diesels, you have actually program the truck to roll coal because they will not with a clean tune even with all the emissions system off.

This is a problem. But I think a good part of the problem is unlike most of the developed world, somebody running for office in the government can say he will listen to god and money, not scientist. (Most people I know, if they mention the voices in their head we beg them to get back on meds. But I guess if they could get on the news they could get elected)

As a husband of a senior level III scientist, I can tell you that even they are capable of giving subjective bias data that fits their predetermined mindset.

I implore you to go back and look how and when the recent 2007+ diesel regulations were created and what the market did to reach these numbers. Look at everything from the decreased efficiency of every engine, the mining of added catalyst materials, the creation and emissions from soot burning DPF cleaning machines, the plants that make DEF fluid, the plants that make the DEF jugs, the added pollution from the DEF jugs, the emissions from the truck that deliver DEF, and so on. Then ask yourself if all this was worth the very minuscule amount PM and NOx limit change when the EPA told the manufacturers a number to reach and did not recalculate the impact on what they did to reach it.

Then look into why our emissions regulations are biased toward gas engines even though they spew more greenhouse gases than diesels. Not only that, but also look into why our fuel economy tests are also geared toward attaining the highest number possible for gassers which is why gassers generally do worse than the EPA numbers in the real world and diesels do better. You can also look into other EPA CAFE regulations and how they actually had a reverse effect in many cases by making cars bigger while killing off smaller more efficient vehicles and is one of the reasons why automakers will stop making cars.

Trust me, the EPA is not perfect, but some seem to take what they say as the word of God without question or even knowing what the regulation is. I bet nobody here even knows what the current CO, CO2, PM, or NOx limit is without looking it up or knowing their impact between each regulation, but by God they will defend it to their dying breath because it came from the EPA.

Let me see. A long time ago it was discovered for society to develop past substance farming cities are needed to concentrate market and labor. I think most who live in city do so because that is where the jobs are. It is pure ignorance to think any vehicle will pollute less driving 100 miles a day instead of 10.
But most important, who in sam hill is forcing you or anybody else to pay the cost? When I lived on the farm, we used 2 pickups. When I got old enough to need one, I bought one that was 10 years old. As soon as we knew it would work we could pull the 14 year old one out of service long enough to rebuild the engine. Emission standards have been on heavy duty diesel pickups for what 13 years? If you don't want to pay the cost, drive the old truck, or buy a gasser.

Actually it is not pure ignorance when speaking in terms of PM and NOx. Read more about these two and you will know what I mean. NOx is is only bad in lower atmosphere, but is good ozone in upper atmosphere. In highly populated areas where it does not have time to dissipate in the stratosphere, it is harmful to humans. However, in less populated areas where it does have time to dissipate into the stratosphere to become good ozone, it is not harmful. CO and CO2 on the other hand(which gassers mainly emit) do stay in the air regardless of where you are at.
