when was diesel exhaust fluid required
DEF is required for proper aftertreatment operation of your emissions system. What is Diesel Exhaust Fluid.
What Does Diesel Exhaust Fluid Do.
. Diesel Emission Fluid or Diesel Exhaust Fluid DEF Aqueous Urea Solution 325 is used in the SCR process to reduce emissions of oxides of nitrogen from the exhaust of diesel engines in motor vehicles. This has helped to reduce the pollution emitted by. DEF is clear and colorless and looks exactly like water.
The system was required to measure the quantity and temperature of DEF in the tank and give warnings when level or temperature was beyond acceptable levels. If you decide to ignore the warnings or the circumstances do not allow tank refill the engine is designed to limit its power and fuelling dramatically. It is a non-hazardous solution of 325 urea in 675 de-ionized water.

Diesel engines beginning in 2010 include emissions equipment that requires the addition of Diesel Exhaust Fluid DEF. A catalyst into the exhaust stream of a diesel engine. Trucks using commercial fuel services have recently been under tighter regulations when it comes to this environmental threat.
In response modern diesel engines are required to use diesel exhaust fluid DEF in effort to reduce harmful emissions. DEF is never added to diesel fuel. Ad DEF Exhaust Fluid Complements Your Diesel Engine Oil.
But the most obvious difference is that you need to add diesel exhaust fluid to a separate tank on the diesel vehicle to remove harmful emissions and enable it. EPA Sets Standards for Diesel Fluid Systems. Since 1970 the agency has tightened regulations when it comes to diesel engines.
This fluid reduces NOx and air pollution. Therefore it is essential to maintain high standards of diesel exhaust fluid quality. Prior to 2008 no one had to worry about the emissions that their equipment or vehicles were emitting however the first move came when EPA required all 34 ton or larger to have diesel particulate filters installed.
Since 2010 diesel-powered on-highway trucks in North America have been using selective catalytic reduction SCR as an exhaust after-treatment technique to control nitrogen-oxide NOx emissions. Because a diesel engine burns fuel at a higher temperature you might have to use an exterior heating system in the wintertime. It is injected into the exhaust stream.
The purpose of DEF is to reduce nitrogen oxide NOx concentration in the exhaust emissions produced by diesel engines. EPA has also adopted regulatory flexibility for nonroad equip ment that can be. Environmental Protection Agency EPA has established minimum refill intervals for the diesel exhaust fluid DEE used in selective catalyst systems to reduce nitrogen oxides NOx from diesel engines.
Diesel exhaust fluid is used to reduce NOx emissions. ISO standard 22241 was created to insure fluid quality of diesel exhaust fluid. Diesel Exhaust Fluid DEF also known as AdBlue is a non-toxic colourless odourless and non-flammable fluid.
EPA standards for emissions from heavy-duty diesel trucks have been lowered dramatically since 2001. In 2010 the EPA required diesel engines to reduce their production of NOx nitrogen oxides.
