No but it likely is yours. true emissons is grams or lbs per mile, not
PPM because in a turbo diesel you can delute the PPM in exhaust while
still dumping a lot of polutants volume wise but if you knew this you
would not have made your "crack". Gas engine would run a lot better
today if they had been allowed to skirt around most emission
requirement like diesel have in the past. It will be a more level
playing field starting in 2008 and it will get stricter every year for
diesels until they basically catch up with gassers.
The "new" diesels will start coming with catalytic converters, which
will do a lot of scrubbing against the NOx? Thats the biggest reason
why sulfur is being eliminated - so you can actually use an effective cat.
Now, if Cummins/Chrysler was just smart enough to start extracting the
waste heat in the exhaust system to do something productive... BMW has
managed to extract another 20-30% from exhaust heat alone.
You do realize you can run a diesel on a lot more than just a diesel,
right? Spray some hairspray, propane, or whatever else in a diesel's
intake sometime and see what you get. Avoid 'cleaner' products as
they'll wipe the lubrication right off the cylinder walls.
While they will start using CAT's in 08, diesels make so much NOx that
they cannot controll it with CAT's alone. They are experamenting with
different methods of capturing or converting NOx and one of those
methods include ammonia injection in exhaust manifolds.(either from a
cartridge that you must change regularly or have a seperate tank for
it that you refill from time to time) If you read and researched more
before you commented you would know what a serious problem NOx
reduction in a diesel presents for Detriot. They are not happy that
their loop hole is being closed. And it get "better" yet, California
has set CO2 limits on vehicle emission that start taking effect in
about 2009 which REALLY has Detriot worried and shakey in their boots.
They are fighting it vigorously in court (they will not win though as
legal advisors have stated from the beginning) and being that 1 out of
every 5 vehicles made is sold in California, it is just a question of
time before it becomes federal too. When that happens it will do what
high gas prices have not been able to do yet, kill big SUV sales
completely because they will have to start building them smaller and
lighter so less CO2 is produced by their operation because in the
scope of things, CO2 is a pollutant too that is over due regulation as
Guess again, it is still a thermo reactor because the sulpher in
diesel fuel will kill a CAT (this is the reason they removed it from
gas long ago) THe reason it smell different today is because of
improvement in injection and the amout of sulpher being reduded for
EPA mandate to require true CATS to be installed on diesels starting
with 08 models. Many mistakingly call them CAT's.
Well, Sno says they're not cats, so he's right and everyone else is wrong...
Had he said that starting in '07 (of course, he's convinced the new diesel
emissions regs kick in starting in '08... whatever), diesels will be using
THREE-WAY cat-cons, instead of the two-way cat's that have been used in the
past - he'd almost sound like he knows what he's talking about.
Ah well... what do we know. We still think 8.0" and 8.25" are distinct and
unique measurements. Sno says they're the same. Go figure...
It seems like dodge could put the 2.7 mercedes diesel in the dakota without
much trouble.there would obviously have to be a good sized market for that
in order for them to do it.maybe gas prices being what they are people may
opt for the more efficient diesel.another option would seem to be the 4
cylinder version of the cummins b (i believe it is a 3.9) that is used in
bread and snack trucks and the like.
Putting a diesel in an American half ton would be a disaster. The full fuel
infrastructure simply isn't there as many of the gas stations don't sell it
and the ones that do usually only have it at one pump or island. This would
cause long lines. The massive increase in demand would also cause a
significant increase in fuel costs, especially during the winter where it
would also cause a significant increase in the cost of home heating fuel.
Another problem is the torque created by a diesel can be pushed way above
what the drive train of most 1/2 ton trucks can handle which would either
force them to heavier duty components in or deal with a lot of pissed off
customers when they refuse to do warranty work due to owner modifications.
Either way, the bottom line would be a significant loss of profits that they
are unwilling to deal with at this time.
