I was searching the net for articles on improved emissions for diesel engines and came across this article.
http://www.anl.gov/OPA/frontiers/d5ee.html
Some important points in the article say:
"When the oxygen in the engine increases from
the ambient 21 percent to 23 to 25 percent, particulates and visible smoke drop dramatically."
"Using a 1.9-liter Volkswagen passenger-car diesel engine, researchers are also investigating new techniques for nitrogen enrichment to cut NOx emissions. Engine manufacturers currently use exhaust gas recirculation (EGR) as a way of reducing NOx. Argonne has found that a nitrogen-rich stream in lieu of EGR is superior, especially in reducing engine wear."
If this or similar technology is able to be brought into the consumer market, I think that it would really make a strong case for the diesel engine as the engine of choice for most people.
The only remaining major negatives that I see would be acceleration and possibly the smell of the diesel fuel. Although, I do not exactly think that Gasoline fuel aroma is that much better than diesel.
I am not completely familiar with all the ins and outs of diesel engines, but this website has improved my knowledge of diesel engines and to a lesser extent of gasoline engines.
Has anyone else heard about this or other technology that would reduce emissions without the use of EGR?
Sincerely,
Anthony
