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. 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.
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 take advantage of Diesel Exhaust Fluid for?
Diesel engines are necessary to meet up with stringent emissions specifications in 2010. Several diesel engine companies have chosen an engineering referred to as Selective Catalytic Reduction (SCR) to fulfill 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.
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?
Along with reducing NOx emissions, the usage of DEF and SCR engineering will typically lead to improved fuel mileage for many 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 can DEF be distributed and saved?
DEF will be stored in dedicated containers and dispensed via highly specialized dispensing models. Using substandard gear can contaminate the DEF and subsequently poison the SCR Catalyst.
