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 updated with what may not be considered cutting edge data.

Precisely what is 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 developed from synthetic ammonia and carbon dioxide and when subjected to high temperature and pressure and might be produced in 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 necessary to meet up with stringent emissions specifications in 2010. A lot of diesel engine makers have chosen a technological innovation named 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 automobile, pickup truck, tractor or any diesel driven product with SCR technologies 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 common DEF tank will probably be approximately 15 – twenty gallons, thus necessitating a fill in every 5,000 to 6,000 miles.

Does temperature impact this product?

Yes. Storage temperature in-between 40?F and 80?F is suggested to maintain product shelf life. Storage temperature above 12?F is suggested to prevent crystallization which begins at 11?F. Extended storage above 86?F will trigger hydrolysis to occur, using the consequent development of ammonia and stress rise, and will decrease shelf life and item effectiveness.

What benefits 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 amount of improvement will differ determined by your equipment. Many inside the sector feel that 3 – 5% improved gas economy will be understood making use of 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.
