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 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 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 primarily in fertilizers but can also be used in plastics, pet feed, cleansing agents, and pharmaceutical programs.

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 included in the exhaust gasses Diesel Exhaust Fluid lowers the NOx towards the EPA required stages. 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 needed?

The consumption price of DEF is in between 2-4% from 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 typical DEF tank is going to be approximately 15 – twenty gallons, thus demanding a fill for every 5,000 to 6,000 miles.

Is this product afflicted by temperature?

Yes. Storage temperature within 40?F and 80?F is suggested to take care of product shelf existence. Storage temperature above 12?F is advised in order to avoid crystallization which commences 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 advantages are there to DEF and SCR technologies?

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 stored in dedicated containers and distributed using highly specialized dispensing models. Using low-standard tools can contaminate the DEF and subsequently poison the SCR Catalyst.
