We had to start using passive PM soot traps in the mid 90s, most diesels sold in the US had to have very high pressure common rail full electric injector control by 2000 to control NOx and PM, early 2000s egr coolers were needed to reduce NOx, 2007 was the ultra low 7ppm sulfur fuel roll out, then in 2010 active soot trapping using exhaust filters that regen and strict NOx emissions, 2013 or 2014 very strict NOx regulations force use of urea augmented converters on most diesels.
Here it is 10ppm and it is legally called non-sulfur diesel

Well this is all new information for me about the american emission equipment, thank you for that.

I don't know when they started reducing sulfur in european diesel, one finnish refinery did it in 1991.
Someone with better knowledge can correct me.
