First, by producing Ultra-Low Sulfur Diesel (ULSD) fuel, which burns more cleanly than earlier forms of diesel fuel. And second, by developing a certification program for Diesel Exhaust Fluid (DEF). DEF is a liquid that is injected into the exhaust system of diesel vehicles from a container located under the hood in most cars.
