Things You Need to 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 may already know all the wonderful world of diesel exhaust fluids, and a few of you fleet managers are just getting vehicles now that require DEF. To keep everyone updated with what may not be considered cutting edge data.

What’s 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 part 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 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 added to the exhaust gasses Diesel Exhaust Fluid decreases the NOx to your EPA required amounts. 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 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 influenced by temperature?

Yes. Storage temperature in between 40?F and 80?F is suggested to keep up 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 advantages 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.
