DIESEL TRUCK CONTROL TECHNOLOGIES THAT COULD BE ENABLED (OR IMPROVED) BY LOW -SULFUR DIESEL FUEL *

Technology	Pollutant(s)	Impact of Low-Sulfur Diesel Fuel
Oxidation Catalyst	Particulates, toxics, hydrocarbons, carbon monoxide	Improves
DeNOx Catalyst ("Lean-NOx catalyst")	NOx, particulates, toxics, hydrocarbons, carbon monoxide	Improves

NOx Adsorbers ("NOx traps")	NOx, particulates, toxics, hydrocarbons, carbon monoxide	Enables
Selective Catalytic Reduction	NOx, particulates, hydrocarbons, carbon monoxide	Improves
Non-Thermal Plasma	NOx, particulates	Probably Improves
Catalytic Particulate Filter	Particulates, toxics, hydrocarbons, carbon monoxide	Improves
Continuously Regenerating Diesel Particulate Filters	Particulates, toxics, hydrocarbons, carbon monoxide	Enables
