In 2010 the Environmental Protection Agency, OEMs, and many trucking fleets committed themselves to a cleaner environment by reducing NOx emissions. To reduce NOx emissions, most new trucks are equipped with a Selective Catalytic Reduction (SCR) system. The SCR technology requires the use ofDiesel Exhaust Fluid (DEF).EPA Emission Requirements:
The Challenge Facing Heavy Duty OEMs For 2010:Further Reduction Of Oxides Of Nitrogen (NOx)EPA Emission Requirements:PM (g/hp-hr)
What is SCR Technology?SCR is an acronym for Selective Catalytic Reduction. It is a catalyst installed on the exhaust system of a diesel truck. It sprays DEF into the exhaust stream to mix with exhaust gases to convert to nitrogen and water.
