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 exactly 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’s urea?

Urea is the active part 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 take advantage of 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 added towards the exhaust gasses Diesel Exhaust Fluid minimizes the NOx for the EPA required ranges. If you purchase a vehicle, vehicle, tractor or any diesel run 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. 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 standard DEF tank might be approximately 15 – twenty gallons, thus necessitating a fill 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 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 lead to hydrolysis to occur, together with the consequent development of ammonia and force rise, and will lessen shelf life and merchandise 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 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 can DEF be distributed and saved?

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