DEF, short for diesel exhaust fluid, is a component in diesel engines to reduce harmful emissions and improve environmental sustainability. Diesel exhaust fluid is made from a formulated mixture of urea and deionized water and is injected into the exhaust stream of diesel vehicles that have Selectiv...

Diesel Exhaust Fluid (DEF) is a 32.5 % solution of high-purity, synthetically manufactured urea in de-mineralized water. It is a safe-to-use fluid that is used in diesel engines with SCR systems to reduce emissions. Yara, adiesel exhaust fluid (DEF)producer, launched the first-ever DEF l...
The use of diesel exhaust fluid (DEF) has ballooned in North America. To prevent DEF contamination, diesel fueling sites that require DEF bulk storage and remote dispensing system installations should meet minimum requirements. The Environmental Protection Agency (EPA) requires diesel-powered, on-road...
Diesel Exhaust Fluid (DEF) is a solution used in modern diesel engines to reduce harmful emissions of nitrogen oxides (NOx) into the atmosphere. It is a key component of a system called Selective Catalytic Reduction (SCR), which is designed to meet strict emissions standards and regulations, ...
For those not willing to accept the changes there has been a shift to older used diesel engines or remanufactured diesel engines that have been grandfathered in. This article aims to go over the cold hard facts about DEF and educate the populace into making smarter diesel operator decisions.1....
Shell Rotella® exhaust fluid for diesel engines helps reduce harmful emissions. It meets the ISO and OEM requirements and is certified DEF. Learn more.
ENGINEERED: For use in Selective Catalytic Reduction (SCR) systems on diesel engines EFFICIENCY: BlueDEF diesel exhaust fluid is key to helping improve fuel economy by up to five percent Do I Add DEF to My Diesel Fuel? No! You absolutely do NOT add DEF to your diesel’s fuel tank. DEF...
Diesel engines are responsible for high NOx emission rates in the atmosphere. The urea-selective catalytic reduction (SCR) system is one of the most promising techniques for NOx emission control. The SCR system uses a urea solution known as Diesel Exhaust Fluid (DEF) that contains 32.5% (v/v...
