That's the first I've heard of anyone proposing to retard timing to lower NOx -- is anyone actually doing this? A catalytic converter would do the job with no loss of power or milage, and no increase in particulates. Of course, you couldn't run our high sulfur dinodiesel thru it then, but certainly you'd have problems running dinodiesel anyway if you retarded the injection timing, more smoke, less power, poor milage, etc. Bad idea all the way around.
