What You should Know about Diesel Exhaust Fluid

It seems like diesel exhaust fluid or DEF since it is mostly referred to as is here to remain for a while. Today, most of you could already know each of the wonderful world of diesel exhaust fluids and several of you fleet managers are just getting vans now that want 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 element 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 largely in fertilizers but can be used in plastics, pet feed, cleansing agents, and pharmaceutical purposes.

What would I take advantage of Diesel Exhaust Fluid for?

Diesel engines are necessary to meet up with stringent emissions demands in 2010. Numerous diesel engine producers have chosen technologies known as Selective Catalytic Reduction (SCR) to satisfy 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 needed?

The consumption fee of DEF is amongst 2-4% on 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 afflicted by temperature?

Yes. Storage temperature in-between 40?F and 80?F is suggested to maintain 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 lead to hydrolysis to occur, together with the consequent development of ammonia and force rise, and will lessen shelf life and merchandise 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 amount of improvement will differ determined by 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 being stored in dedicated containers and dispensed by way of highly specialized dispensing models. Using substandard gear can contaminate the DEF and subsequently poison the SCR Catalyst.
