I spoke to a trucker about this and took some picture of the stuff
needed to clean the carcinogenic particulates from the exhaust. The
World Health Organization has deemed diesel exhaust hazardous to
your health. Millions of old diesel powered cars are upping the
cancer rate in Europe.
The estimated cost of retrofitting a truck is $15,000. The cost of
the Diesel Exhaust Fluid is $15 a gallon. Many Cal companies are
selling their current trucks out of state. Many small truckers are
going out of business in California. You must have one of these Air
Resources Board stickers on your truck wind shield before you can
enter California.
This has increased the cost of shipping in California.
A large turbo compound rotary Wankel would make a great truck
engine due to it's robust and cannon proof design. There is no
doubt in my mind it would last as long as a diesel engine and get
equal or better MPG. Fuel price per gallon would be less. It would
weigh less than a diesel as well increasing the payload. It would
also be smoother. Large size is no problem. Some of these huge
Ingersoll Rand engines are rumored to have run for 20,000 hours.
I am probably way ahead of my time on this one as well.

Hi!: below please find one of the many references available in
Entrez PubMed, MedLIne, about the carcinogenic effects of Diesel
exhaust smoke, the nature and composition of the exhaust gases in a
Diesel, and the amount of particulates, those that give the black
smoke look to the exhaust of Diesel engines may vary, but as long
as the injection pump system is not adequately tuned, smoke in the
exhaust, performances and fuel economy will worsen.

"RESULTS:
We observed statistically significant increasing trends in lung
cancer risk with increasing cumulative REC and average REC
intensity. Cumulative REC, lagged 15 years, yielded a statistically
significant positive gradient in lung cancer risk overall (P
(trend) = .001); among heavily exposed workers (ie, above the
median of the top quartile [REC ≥ 1005 μg/m(3)-y]), risk was
approximately three times greater (OR = 3.20, 95% CI = 1.33 to
7.69) than that among workers in the lowest quartile of exposure.
Among never smokers, odd ratios were 1.0, 1.47 (95% CI = 0.29 to
7.50), and 7.30 (95% CI = 1.46 to 36.57) for workers with 15-year
lagged cumulative REC tertiles of less than 8, 8 to less than 304,
and 304 μg/m(3)-y or more, respectively. We also observed an
interaction between smoking and 15-year lagged cumulative REC (P
(interaction) = .086) such that the effect of each of these
exposures was attenuated in the presence of high levels of the
other. CONCLUSION:
Our findings provide further evidence that diesel exhaust exposure
may cause lung cancer in humans and may represent a potential
public health burden."
I was told the Ultra Low Sulfur diesel would fix almost all these
problem. Did they lie to a journalist? Horrors. Was the journalist
not smart enough to figure out how to doublecheck their claims? You
bet. ...Mac Demere
All this AND Ultra Low Sulfur diesel.

I'd say that the ultra-low sulphur fuel what it does, and what it's
intended for, is avoiding the emission of Sulphur Oxides, SO2, that
in contact with water generate acids, that are even more toxic to the
lung that the sulphur oxides itselves, and also produced 'acidrain',
don't think in drugs, please, acid rain that destroys forests and
outer layers of buildings, is a high contributor to the toxicity of
'chemical smog', and has noticeable effects on overall rainfall, even
in distant places, it was shown that the content of sulphur in fuels
used in England and other European countries was responsible of the
worsening of periodic droughts in the African zone of lake Tchad, and
the improvement in th equality of european fuels resulted in better
rainfall conditions in some parts of Africa. As far as I know, the
amount of sulphur allowed in the fuels sold in western Europe, if
there's any amount of sulphur allowed, prevents this things
happening, but as with any other internal combustion engine, an out
of tune Diesel motor is a disaster, both in terms of fuel economy and
emissions, and even the best fuel available won't solve or improve
this. Particulates, the black smoke, unburned hydrocarbons and
nitrogen oxides are the dangerous emissions from Diesels, perhaps in
this order of importance, as HCs and NOx are the dangers of gasoline
engines' exhaust. Catalyze rs help, in Diesel and in Gas engines, but
I don't know if its efficiency is 100%. My loved solution for
reciprocating engines is Single-Sleeve-Valve distribution,
Burt-McCollum type, you can watch it in Wikipedia, but today's auto
makers are using more sophisticated approaches to improve ICEs
performances, fuels may vary a lot from place to place, and even from
a season to another, for example, I owned a small car with a 1.2
liter 4 cyl engine, that worked well with the leaded gasoline
available in 1984 in Spain, but had audible detonation, knocking,
with the unleaded regular German gasoline, and many old cars are using
today in Europe a liquid additive, to be dropped to the fueling hole
when adding fuel to the tank, composed mainly of potassium (K) salts,
with no negative environmental effects, to substitute the effect of
lead in valves, and not having an engine destroyed because it was
designed for leaded gasoline, and used with unleaded gas. Times they
are a'changing, but some basic things can't change as it's the nature
of ICEs.
