from what i heard that urea sensors will be programed into trucks so when you run out of it it will shut down your truck,at least that is what they tell us at semi dealerships. also they say when it comes out that truck stops and fuel stations that sell diesel will have urea too

 

yep Pilot is already working on putting Exhaust Fluid fillers in at their stations, which is essentially urea from what i can gather

 

Hmm, wonder what the slide-rule boys have designed into the aluminum head to make it live...

 

Ok, I am going to show my ignorance now on this, but what exactly is the urea supposed to do to improve exhaust emission? Wouldnt adding urea (nitrogen) to the exhaust help to create nitric acid into the atmosphere?
