摘要

What you need to know about Diesel Exhaust Fluid. Over the last 10 years, many engine manufacturers have incorporated a Selective Catalytic Reduction (SCR)exhaust emissions aftertreatment system that was mandated by the EPA back in 2010 on diesel engines. This technology is used to reduce the Nitrogen Oxides (NOx)emissions of the engine so that it meets current U.S. EPA and California exhaust emission requirements. What is DEF? DEF (Diesel Exhaust Fluid) is a colorless, non-hazardous and non-flammable chemical used in all medium and heavyduty diesel vehicles to significantly reduce engine emissions. If DEF comes in contact with the skin, it can simply be washed away with water.
