Chrysler Eco Diesel Emissions Tests by EPA maybe another dieselgate

The particulates contribute to climate change (if you believe in it) due to heat absorption. I had an apartment in Europe with a balcony adjacent to a road. Every thing on the balcony would literally turn black from the diesel particulates.

I'm a big diesel fan, too. When I hear people complain about it, it's always the smell. They say it stinks going in, and it stinks coming out. If the petroleum industry could make diesel fuel smell like peppermint tutti-fruiti going in and caramel mocha latte coming out, I think more people would get on the diesel bandwagon.

The myth of " Clean Diesel is right up there with "Clean Coal Technology " and " Smoking isn't Harmful to your Health" .
No perfume will cover up the foul stench of diesel .
Diesel engines have their place and make sense for commercial ,industrial and work applications but are of questionable value in commuter vehicles. Diesel owners touts the MPG's they get with their small diesel vehicle but some how overlook all the negatives that also come with the vehicle .

Last summer I replaced my Jeep Grand Cherokee after 93000 miles and only had a bad fuel pump relay once in that time. I again considered a diesel version to have close to 400# torque but again went with the Hemi engine but in the Dodge Durango because I wanted two wheel drive for the sunny climates. We now have nearly 6000 miles and I guess it must be broken-in since the trip to PHX and back 260 miles we got 22.6 mpg at 70 to felony speeds. The computer claimed 23.6 but actually it was the 22.6. We get 16 to 18 around town and 15 to 16 towing. Now if I could talk Nancy into switching her gas Fiat convert for an electric one if they start selling them in AZ. Now I'm glad I don't have the diesel and I hope our son-in-law can get his Jetta diesel sold back soon.

The vast majority of the abundance of food we take for granted in this country is planted, harvested and distributed using diesel fuel. I don't think we will ever see a grain combine capable of harvesting 150-200 acres of wheat per day running on solar power. If we ever run out of diesel fuel in this country, a lot of people will need to start liking the taste of tree bark. Now I'll step back off my political stump.

Transportation uses immense amounts of diesel fuel, trains, trucks, ships. As well, most of the US Forces vehicles are diesel powered as well. Diesel (or all fossil fuels) is a long way from not being used at all.

Best of both worlds, a diesel in the driveway, and a fat bike on the ski trail. This mornings commute, a balmy -8.

It's all a Machavelian / Communist plot secretly led by the Russians , Chinese , oil companines , government , auto companies ,environmentalists , vegetarians , radical socialists , scientists and Muslim extremist.
If you don't like dirty air just stop breathing & complaining.

My wife has COPD and has trouble breathing . Diesel exhaust fumes are a particularly tough problem for her . One of the reasons we moved from a major city to a rural area was to get away from diesel exhaust fumes as well as other pollutants.

I'm sorry for your wife's illness, but my comment had nothing whatsoever to say about "conspiracy theories". The war on diesel is highly politicized, but that doesn't mean the various entities that are opposed to it are conspiring.

Ok, is the EPA valid ?

Of course it is, although that too has been politicized more than I'd like. The key is an emissions standard, and the advancement of ultra low sulfur clean diesel technology. Some diesel engines today produce even less particulate emissions than their gasoline counterparts. I say keep the advancements coming.

It just seems that anytime the scientific community comes up with a finding that does not agree with someone's personnal opinion , they attack the scientists and accuse them of having an agenda .
The scientist often are not the ones politicizing the issue but it's being done by those who have a financial stake in the outcome.
Small diesel engines create a lot of pollution and by nature will have a difficult time meeting modern air quality standards.
If someone can design and build a clean small diesel engine , it would be beneficial to all of us . I am not anti diesel but I am anti dirty air.
There are groups that are anti diesel but not necessarily for self serving reasons or for political gain.

PS; I wasn't responding to your post cause I never read it.

I think the frequent on/off used in newer hybrid and ecoboost engines will doom small diesel engines for the automotive market although there will still be a major use of them in trucking and diesel/electric applications...and fracking.

I'm guessing that LNG will become a much more common fuel since fracking technology has awarded us with an unlimited supply of natural gas and if it isn't used it ends up getting flared off which is a horrible waste of energy. The major shipbuilding yards in North America have been busy for several years now building LNG carriers and LNG export terminals are getting built in Texas and Alaska.

No worries Steve. I agree with much of what you say, but I guess I don't have as much faith in the "scientific community". First, because it's not really a single entity, despite what some would have us believe, and second, because the "community" often does have an agenda, and has been proven wrong. Just look at the dire warnings about climate from the scientists of 30 years ago. Every single prediction they made about the worldwide cataclysms coming in the next few decades turned out to be completely wrong. Concensus often can translate to group think, and often, that's not sound science.

Amen to all you wrote Bryan.
Add to that - politicization of most government departments.

Well, good, I guess we can stop worrying about those chunks of Antarctica the size of small states breaking off, all those record high temperatures all over the globe and charts like this from those "group thinkers" all across the planet. Luckily they will all soon be proved wrong once we depoliticize those departments
