Most of the black smoke/soot that diesels are "notorious" for is more the driver's fault than the engine's.
Drivers are seldom to never trained to feed fuel to the engine (aka "accelerate") only as fast as it can accept it. The black smoke is incompletely combusted fuel caused by fuel overload.

The oxides of nitrogen don't actually come from the fuel, there is no nitrogen in standard diesel fuel to speak of. The NOx are created in the combustion of the fuel, so it is the chore of the engine manufacturer, not the fuel maker to control NOx. Fuel refiners will have a hard time controlling NOx, no matter how clever they are. But, in total, this is excellent news. The EPA estimate is that this action alone will save 12,000 lives a year !! by the time all of the old equipment is replaced with new technology. Don't hold your breath for that to happen, some of these machines will last 50 years from now, still belching black smoke. It is biodiesel that can make the difference here, reducing "black smokers" by more than 50% in particulate matter and unburned hydrocarbons. I have run a few experiments that reduced soot levels by up to 80% when 80% biodiesel was added to the tank, in just 2 hours! The registry ran the final test twice since they couldn't believe a truck could be that much improved in a single day. Even better, the latest University of California study showed a 93% reduction in carcinogens (nPAH's) when biodiesel was used, instead of regular fuel.
