Facts about Diesel Exhaust Fluid that You should Know

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 educated with what may not be considered cutting edge details.

Precisely what is Diesel Exhaust Fluid?

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

What on earth is urea?

Urea is the active component of DEF. Urea is made from synthetic ammonia and carbon dioxide and when subjected to higher heat and pressure and may be produced as being a liquid or solid. Synthetic urea is used mostly in fertilizers but is additionally used in plastics, pet feed, cleansing agents, and pharmaceutical apps.

What would I take advantage of 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 necessary?

The consumption fee of DEF is amongst 2-4% on the diesel fuel consumption. As an example, for every a hundred gallons of diesel gasoline consumed, between two and four gallons of DEF will likely 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 within 40?F and 80?F is suggested to take care of product shelf existence. 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 benefits is there to DEF and SCR technology?

As well as reducing NOx emissions, using DEF and SCR technological innovation will typically cause improved fuel mileage for the majority of vehicles. The quantity of improvement will differ according to your equipment. Many in the market feel that 3 – 5% improved gasoline economy will be recognized employing DEF and SCR systems.

How can DEF be distributed and saved?

DEF is being stored in dedicated containers and dispensed by way of highly specialized dispensing models. Using cheap products can contaminate the DEF and subsequently poison the SCR Catalyst.
