How SCR Technology Works
3.
Then the exhaust is combined with the diesel exhaust fluid (DEF), sent through a final SCR Catalyst to remove NOx, and finally, water and nitrogen are released into the air.
2.
After the exhaust leaves the engine, it runs through a diesel oxidation catalyst and a diesel particulate filter to remove soot and particulate matter.
1.
Selective Catalytic Reduction uses basic chemistry to reduce NOx emissions through a process that is simple, extremely efficient, very reliable and safe. The major components of the process are hot exhaust, Diesel Exhaust Fluid and catalytic converter.

About DEF
What is Diesel Exhaust Fluid (DEF)?
Diesel exhaust fluid (DEF) is a urea-based solution that reduces harmful nitrogen oxide emissions from diesel engines. DEF is composed of 32.5% high-purity urea and 67.5% deionized water. DEF is clear, odorless and safe to handle.
The solution is added to a separate storage tank in diesel-powered vehicles equipped with selective catalytic reduction (SCR) technology. The fluid is injected into the hot exhaust stream of the vehicle and helps break down the nitrogen oxide gases in the exhaust into nitrogen gas and water vapor, both harmless to the environment.
Why Use DEF?
It is an inexpensive and efficient option for lowering NOx emissions. Nitrogen oxide (NOx) is produced from the exhaust of diesel vehicles and is a major contributor to smog and other air pollution. Exposure to NOx can also lead to respiratory and heart disease. This is why in 2010, the U.S. Environmental Protection Agency (EPA) mandated that all new diesel engine vehicles reduce NOx emission levels by 90%.
It improves engine performance and fuel efficiency. The combination of DEF and SCR technology not only reduces NOx emissions, it actually improves a vehicle’s horsepower by making diesel engines run more efficiently, resulting in fuel savings of up to 8%.
It is easy to use. Any diesel vehicle with SCR technology can use DEF. There are no special filters or absorbers required. The driver simply fills their DEF tank periodically and the SCR technology handles the rest. A gallon of diesel exhaust fluid costs about the same as a gallon of diesel fuel, but will generally last about 300-500 miles. And since the EPA regulations came into effect, SCR technology is quickly becoming the industry-standard on new diesel vehicles.
It is widely-available. Many truck stops now offer diesel exhaust fluid that can be pumped directly into the DEF tank. It can also be bought in easy-to-handle 2.5-gallon containers at auto stores, gas stations and other retailers. And fleet owners can purchase DEF in bulk storage with custom dispensing solutions.
DEF is short for diesel exhaust fluid and is a urea-based solution that reduces harmful nitrogen oxide emissions from diesel engines. DEF is composed of 32.5% high-purity urea, a naturally-occurring element, and 67.5% deionized water. DEF is clear, odorless and safe to handle.
DEF is the reactant necessary for the functionality of the selective catalytic reduction (SCR) system.
Selective catalytic reduction (SCR) is one of the most cost-effective and fuel-efficient diesel engine emissions control technologies available. For passenger cars and light-duty trucks, it offers the ability to meet strict emissions and fuel efficiency guidelines affordably without compromising driving power and performance. In the commercial trucking industry, including heavy- and medium-duty trucks, the ability to reduce emissions to near-zero levels while also delivering a 3%-5% diesel fuel savings distinguishes SCR as one of the only emissions control technologies that is as good for business as it is for the environment.
Urea is a compound of nitrogen that turns to ammonia when heated. It is used in a variety of industries, including as a fertilizer in agriculture.
The solution is added to a separate storage tank in diesel-powered vehicles equipped with selective catalytic reduction (SCR) technology. During engine operation, the fluid is injected into the hot exhaust stream of the vehicle and helps break down the nitrogen oxide gases in the exhaust into nitrogen gas and water vapor, both harmless to the environment.
The DEF you purchase should state and display the certification of the American Petroleum Institute (API), and meet ISO 22241-1, specifications. This will ensure the proper purity and concentration (32.5%) of urea. Blue Sky DEF meets the ISO specification and is licensed by API. For more information on the specifications, visit www.iso.org.
API certification is a voluntary program established by the American Petroleum Institute (API) that certifies and monitors that diesel exhaust fluid meets ISO specifications. The program was launched in March 2009. Blue Sky DEF currently meets ISO specification and is also API certified.
A basic rule of thumb is that for every 50 gallons of diesel fuel you will need one gallon of DEF. A gallon of diesel exhaust fluid will generally last about 300-500 miles.
To determine your specific needs, use our handy DEF Calculator.
It is not recommended that customers fill bottles of DEF for use in SCR systems due to the strict ISO requirements for maintaining DEF purity. SCR systems are sensitive to potential chemical impurities in DEF. Reusing bottles introduces the possibility of small droplets of leftover DEF crystallizing and plugging the DEF filter, which will directly compromise the SCR system.
It is not recommended to let your tote become completely empty. Totes should be refilled once there is approximately 2-3 inches of DEF left inside the tote. Allowing the tote to become empty introduces the possibility of small droplets of leftover DEF crystallizing and plugging the DEF filter, which will directly compromise the SCR system.
Yes, the 32.5% urea concentration is ideal as it provides the lowest freeze point. In addition, SCR systems are calibrated to the 32.5% concentration for optimum reduction of nitrogen oxide emissions during operation.
A 32.5% solution of DEF will begin to crystallize and freeze at 12˚F. In a 32.5% solution, both the urea and water will freeze at the same rate, ensuring that as it thaws, the fluid does not become diluted or over-concentrated. The freezing and thawing of DEF will not cause degradation of the product.
Yes, DEF expands by approximately 7% when frozen. DEF packaging and tanks are designed to allow for expansion.
During vehicle operation, SCR systems are designed to provide heating for the DEF tank and supply lines. If DEF freezes when the vehicle is shut down, start up and normal operation of the vehicle will not be inhibited. The SCR heating system is designed to quickly return the DEF to liquid form and the operation of the vehicle will not be impacted. The freezing and thawing of DEF will not cause degradation of the product.
The shelf life of DEF is a function of ambient storage temperature. DEF will degrade over time depending on temperature and exposure to sunlight. Expectations for shelf life as defined by ISO Spec 22241-3 are the minimum expectations for shelf life when stored at constant temperatures. If stored between 10˚F and 90˚F, shelf life will be one year. If the maximum temperature does not exceed approximately 75˚F for an extended period of time, the shelf life will be two years.
No, DEF is a non-toxic, non-polluting, non-hazardous and non-flammable solution. It is stable, colorless, and meets accepted international standards for purity and composition. DEF is safe to handle and store and poses no serious risk to humans, animals, equipment or the environment when handled properly.
If DEF is spilled, contain the spilled liquid and absorb it with an inert, non-combustible absorbent material, such as sand. Shovel the material into a suitable container for disposal. Spills into a drain should be avoided. If spilled into a drain, flush thoroughly with water. If DEF is spilled on your vehicle, rinse with water.
DEF is corrosive to copper and brass as well as other materials. Only approved materials, such as high density polyethylene (HDPE), will be used in the DEF tank, packaging and dispensing equipment.
The standard nozzle diameter for dispensing DEF has been designed at 19 mm versus the standard diesel fuel nozzle diameter which is 22 mm. In addition, the tank cap for the DEF tank is blue in color to further differentiate from the diesel tank.
The SCR system will recognize solutions other than DEF, and the DEF indicator light will appear notifying the driver. Depending on the level of contamination in the tank, the vehicle may require servicing.
It is essential that DEF is stored and handled properly so that it remains pure and functions as it should. Even the smallest amount of contamination can compromise the effectiveness of DEF and lead to the breakdown of the SCR system. This means that certain handling instructions must be followed:
-
DO NOT MIX WITH DIESEL FUEL
-
Optimal storage temperature: 23˚F to 77˚F
-
DEF will freeze at 12˚F
-
Avoid direct exposure to sunlight
-
ISO 22241 standards require the use of only stainless steel and/or certain plastics, such as high density polyethylene (HDPE) or polypropylene, to store DEF in order to prevent contamination and SCR failure.
-
Materials specifically not recommended include non-ferrous metals and alloys (copper, aluminum, magnesium, silver, zinc and lead), solders containing non-ferrous metals, and nickel-coated plastics and metals.
