... I've made a prediction on Edmunds that urea systems will be obsolete before the last truckstop in California has the pumps and tanks installed. So: we have the relatively new Argonne Labs patent for NOx reduction, and today we have breaking news that Eaton Corp. and Clean Diesel Technologies are collaborating on a system that will improve Eaton's system that does not require on-board tanks or a couple hundred million of infrastructure. Geeshe, what a novel idea: USA technology for a USA and Earth problem. .. ... I am sure the bean counters in Pilot and TA told the execs that they are the smartest guys in the room, because it's as simple as this: look at Europe: X amount of regs, equals X amount of fuel, equals X amount of urea, BUT did they tell you this technology might be ten years old by the time you have it implemented. Maybe that is the problem, the bean counters and the reg makers are building engines. It might actually be a fortuitous time for Flying J to be in Chapter 11 as they should come out the other side of this and not have truckers haul away their probably hazardous ammonia tanks. Arnold, why not save the State and the trucking industry, a few hundred million and stop this nightmare before the first one goes in the ground ??? But wait, don't forget Homeland Security on this deal !!!

Well we know that eight years of an oil administration that could do nothing right what are we up against with the coming Clinton 2.0' or Obama for those that have not noticed.

Replying to: roland3 (Jan 11, 2009 2:06 pm) Quite a number of the diesel cars here in Europe use Disel Particulate Filters, (DPF). They appear to be potentially troublesome if car only wanders around town and the exhaust doesn't get really hot, (enough to burn off the nasties). Dashboard message comes up so you need to go do a circa 20 minute run at 50mph to get it all hot and clean. Miss that opportunity and it's down to min power and a trip to the dealer for cat cleaning. Get caught with this 3 times and you may well need a new cat............and that's not a warranty item in those circumstances, apparently. Anyway, that's my simplistic take on the topic. The link is better, (it's from a leasing company). Let me make it clear that I don't know anyone who has had this problem, (and most of my friends drive modern diesels), but it does appear on various Forums from time to time - and gets a lot of attention; as "bad" things always do. Enjoy. DPF

Continental Airlines tested a Boeing 737-800 using biofuel on one engine and normal jet fuel on the other. Worked great. http://www.chron.com/disp/story.mpl/business/continental/6199665.html
