Facts about Diesel Exhaust Fluid that You should Know

It seems like diesel exhaust fluid or DEF since it is mostly referred to as is here to remain for a while. Right now, most of you could already know every one of the wonderful world of diesel exhaust fluids, and many of you fleet managers are just getting vehicles now that need to have DEF. To keep everyone educated with what may not be considered cutting edge details.

What’s Diesel Exhaust Fluid?

Diesel Exhaust Fluid or DEF is a high purity chemical substance solution containing 32.5% urea and 67.5% deionized water.

Exactly what is urea?

Urea is the active part of DEF. Urea is produced from synthetic ammonia and carbon dioxide and when subjected to substantial high temperature and pressure and will be generated being a liquid or solid. Synthetic urea is used primarily in fertilizers but can also be used in plastics, pet feed, cleansing agents, and pharmaceutical programs.

What would I take advantage of Diesel Exhaust Fluid for?

Diesel engines are necessary to meet up with stringent emissions demands in 2010. Several diesel engine companies have chosen an engineering referred to as Selective Catalytic Reduction (SCR) to fulfill these requirements. When included in the exhaust gasses Diesel Exhaust Fluid lowers the NOx towards the EPA required stages. If you purchase an auto, pickup truck, tractor or any diesel driven product with SCR technology, it would require DEF.

How frequently will refueling of DEF be necessary?

The consumption charge of DEF is among 2-4% in the diesel fuel consumption. For instance, for every one hundred gallons of diesel gas consumed, between two and four gallons of DEF will probably be automatically injected into the exhaust system. The standard DEF tank might be approximately 15 – twenty gallons, thus necessitating a fill every 5,000 to 6,000 miles.

Is this product influenced by temperature?

Yes. Storage temperature in between 40?F and 80?F is suggested to keep up product shelf life. Storage temperature above 12?F is advised in order to avoid crystallization which commences at 11?F. Extended storage above 86?F will result in hydrolysis to occur, with all the consequent development of ammonia and strain rise, and will minimize shelf life and solution effectiveness.

What advantages are there to DEF and SCR technologies?

As well as reducing NOx emissions, using DEF and SCR technological innovation will typically cause improved fuel mileage for the majority of vehicles. The level of improvement will differ depending on your equipment. Many inside the sector feel that 3 – 5% improved gas economy will be understood making use of DEF and SCR systems.

How can DEF be distributed and saved?

DEF will be stored in dedicated containers and dispensed via highly specialized dispensing models. Using cheap products can contaminate the DEF and subsequently poison the SCR Catalyst.
