Diesel emission problem solved! Inject urea into a cat converter.(I'm serious).
From a world renowned magazine on Economics
"To meet California’s tough emission standards, carmakers have had to find ways to mop up the diesel’s unwanted NOx and trap its soot. The answer is to inject urea into a catalytic converter in the exhaust. The heat turns the atomised urea into ammonia, which, in turn, converts the hot exhaust gases into nitrogen and water. The soot is trapped by a fine mesh in a particulate filter added to the tailpipe.
Sounds complicated, but the diesel’s extra requirements cost less than you might think. For instance, Mercedes-Benz’s big new diesel sedan (the E320 Bluetec) has a sticker price of $53,025, while the petrol version of the same car costs $52,025. The Mercedes diesel gets 23 miles per gallon in the city and 32 on the highway, compared with 17 and 24 for the petrol version"
