Diesel Exhaust Fluid

in order to protect the environment, keeping the air quality as clean as possible, exhaust emissions regulations around the world have been strengthened considerably. in motor vehicles with diesel engines, particulate matters (pm) and nitrogen oxide (nox) emissions are the main concern, and efforts have been focused on the development of technology which can reduce them effectively with minimum fuel economy penalty. euro vi def is used in  every diesel engine of all the major commercial vehicle, oems across the world who have chosen  selective catalytic reduction (scr) scr to comply with new and upcoming emission standards. scr  is a process that simply adds a diesel exhaust fluid (def) into the exhaust gas stream and filters it through a catalyst. the def vaporizes and decomposes to form ammonia (nh3), which in conjunction with the scr catalyst reacts with nox (nitrogen oxides) to convert the pollutant into nitrogen (n2) and water (h2o) which are released into the air. scr technology uses less fuel since the engine is tuned to cut nox and can instead be set up for performance and economy. in addition, fewer active “regenerations” of diesel particulate filters are needed to burn off soot, which in turn uses less fuel.

usage : 100% concentrated product is to be put into the tank dispensing pump and container should be of alloy steels (ss 304) or plastic. non-alloyed steels, ms, copper, copper-containing alloys and zinc-coated steels should not be used. 

specification followed :

diesel exhaust fluid (def) nox reduction agent aus 32 as per international standard iso 22241.

following are major features for def:

• environment friendly. 
• reduces nox pollution.
• lowers particulated emissions.
• better fuel economy.

important points :

• storage below 35 c and over -11 c is recommended.
• do not store under direct sun light always store in a covered area.
• protect against any contamination of water, fuel, oil, dirt, metals etc.
• always use dedicated instruments for storage and dispensing made from alloy steels (ss 304min) or plastic (hdpe).
• dispensing pump and container should be of alloy steels (ss 304) or plastic (hdpe). non-alloyed steels, ms, copper, copper-containing alloys and zinc-coated steels should not be used. 
• don’t reuse the storage container.
• do not use the dispensing container for any other use.
