Things You Need to 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 exactly is Diesel Exhaust Fluid?

Diesel Exhaust Fluid or DEF can be a high purity chemical substance solution composed of 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 mostly in fertilizers but is additionally used in plastics, pet feed, cleansing agents, and pharmaceutical apps.

What would I exploit 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 added towards the exhaust gasses Diesel Exhaust Fluid minimizes the NOx for the EPA required ranges. 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 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 common DEF tank will probably be approximately 15 – twenty gallons, thus necessitating a fill in 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 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 quantity of improvement will differ according to your equipment. Many within the market feel that 3 – 5% improved gasoline economy will be recognized utilizing 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 low-standard tools can contaminate the DEF and subsequently poison the SCR Catalyst.
