What You should Know about Diesel Exhaust Fluid

It appears like diesel exhaust fluid or DEF as it is mostly named is here to stay 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 knowledgeable with what may not be considered cutting edge info.

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.

What’s urea?

Urea is the active component 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 largely in fertilizers but can be used in plastics, pet feed, cleansing agents, and pharmaceutical purposes.

What would I exploit Diesel Exhaust Fluid for?

Diesel engines are needed to match stringent emissions needs 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 essential?

The consumption price of DEF is in between 2-4% from 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 typical DEF tank is going to be approximately 15 – twenty gallons, thus demanding a fill for 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. The storage temperature above 12?F is recommended to stop crystallization which starts off 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 is there to DEF and SCR technology?

Together with reducing NOx emissions, the utilization of DEF and SCR know-how will typically end in improved fuel mileage for some vehicles. The level of improvement will differ depending on your equipment. Many in the market feel that 3 – 5% improved gasoline economy will be recognized employing DEF and SCR systems.

How will DEF be stored and dispensed?

DEF is stored in dedicated containers and distributed using highly specialized dispensing models. Using substandard gear can contaminate the DEF and subsequently poison the SCR Catalyst.
