I posted this on another thread, but I thought I'd repost it in this forum. I thought he gave pretty good examples of what's coming down the pipe for diesel emissions regulations, as well as some more possible gasoline engine advances.

There will just be a few diesel heads left in the future. Be like the old days, not as much demand for diesel fuel. Maybe the price of fuel will go back the way it was in comparison to gas.

 

I thought i read somewhere that the new 6.7 cummins already meets the 2010 emisions? To me this video is just another excuse to raise the price of Diesel trucks and Diesel fuel.

 

ya Lutz is downplaying the diesel world, but there are plenty of counter arguments.

Sure gas engines could have significant gains, but so could the diesel engine. Why doesn't he put any R&D into the diesel to get it to meet emissions? I find it counter-intuitive to use a fuel that has less energy per volume than diesel, gas and ethanol are good examples here.

Diesel emissions can be cleaned using many methods. The first is to alter the fuel, biodiesel has shown significant impact on reducing harmful emissions. A better fuel system also reduces emissions by reducing the contaminents in the fuel and allow for proper injection timing. Check out the AirDog site for more info.

Granted the diesel engine is more expensive to produce, but properly made they also last a whole lot longer.

 

I'd rather have an 2005 and older mercedes E320 cdi without the emissions crap. At least they will get 38-40 mpg in a full size car instead of the cracker jack boxes the enviromental wackos push that get close to the same mileage. Wonder what they will go after once the climate goes into a cooling off period like the 70s and their global warming fiasco blows up.

 

No matter what the weather does it will be caused by Global Warming. If I get more snow this year then last or less rain then last it will be caused by Global Warming. If hell was to freeze over Global Warming is why it happened. Don't you just love them tree hugger's

 

You know, I just don't trust what any American car person says. It's a sad day when that happens but as I listened to him talking all I could think was, "well, Honda or someone else will figure it out (if they haven't already) and they will own the market."

Just seems like a prime example of American auto makers throwing their hands in the air saying it's too difficult unless they charge a lot more, and then hoping we all buy what they are saying.

Truth be known, they can do it at a decent price but they aren't going too. The NUTS on Wall Street would pass out if GM, Ford, etc. actually got the job done at a decent price. It's all about the money...

 

He's just upset that Cummins and a few others can make a 2010 complaint diesel engine and GM can't or does not want to do it.

 

You Know, I would like to see the overall picture on this Emission Crap. We are loosing out on Fuel economy by trying to make diesel engines "cleaner". If we loose 5%-10% economy by gaining X% emission, is it worth it? Could we be polluting more in the end (Refining more fuel, transporting more fuel and burning more fuel)? And this doesn't just go for our pickups and cars, what about the real deisel users, over the road trucks. If they lose 1 mpg think about the amount of fuel that is applied to all the trucks on the road. I just keep hearing about how "dirty" diesels run, but how dirty are they when compared to gas in a big picture sort of way.

 

Amen brother

 

Why ask why?

Just kidding, I ask the same questions, no one seems to care though!

My other question is always, how much emissions reduction is enough? Each and every year our air quality is improving, yet we pile more requirements on emissions. If we kept Emissions regulations at our current levels, where would our air quality end up?

Then there is the question of population density, OK, so LA is smoggy, has anyone ever asked if a civilized population could pack so many people in such a tight space and reasonably expect clean air?

I see now they are coming for California's outdoor barbecues, when will it end?

 

This may come as a shock to you, but the 2007 cummins ISX gets 1-2% better feul mileage than the previous versions of the ISX even with the regens. For an over the road truck that comes out to be roughly 180 more miles out of the fuel tanks.

Before you all start riping into me saying where is your proof I will tell you. This news came to me directly from the man in charge of the Heavy Duty Diesels at cummins. Needless to say he was very very happy to report this information because the dyno testing of this engine did not show as great of results of actual on road testings.

 

I didn't click the link because I have VERY little use for GM.

I saw a PDF on big truck fuel economy. And I can see a LOT of big trucks going up and down Hwy 59 NOT doing all they can to save fuel.

I hear of folks who have gone back to a gasser, giving up a couple mpg but getting gas at upwards of 50 cents less.

I know I'd give up WAY more than a couple the way my truck is equipped and loaded!

I look forward to viable 1/2 ton diesels in the next few years!

 

plenty of untapped oil in our own country that we are not allowed to drill for- tree huggers-again!

 

I thought that was Bush's fault, isn't it ?
