Selective Catalytic Reduction or SCR is an advanced active emissions control technology system found in newer generation diesel-powered vehicles or modern diesel cars.
SCR is a catalytic reaction that uses Ammonia to decrease oxides of Nitrogen or NOx into harmless Nitrogen (N2) and water. This catalyst is sometimes known as a NOx catalyst in the industry. The SCR system works with AdBlue, and It improves the environmental effects of all diesel vehicles.
First of all, watch this video to become more familiar with Adblue fluid.

This company delivers products such as AUS32, AUS40, and 50% Urea-Aqueous in bulk DEF solutions, mini-bulk storage, or a diesel exhaust fluid tank for diesel-powered vehicles and equipment.
What is AdBlue and Why Do Diesel Vehicles Need it?
Adblue, known as diesel exhaust fuel or DEF, is a solution made from deionized water and high-purity urea. This solution is injected into diesel vehicles and equipment to make the exhaust gasses cleaner.
Some people believe that blue DEF is just for old diesel vehicles, but based on the Euro 6 emissions standards in September 2015, modern diesel engines have been required to produce 80mg/km of oxides of Nitrogen or less.
4 Top Reasons that Modern Diesel Cars Use AdBlue
AdBlue is a specially-formulated liquid that has significant effects on modern diesel engines. Modern diesel vehicles are cleaner than ever before, which is down to the use of AdBlue. Here are the top 4 reasons for using this solution.
Reduces Harmful Emissions and Air Pollution
AS we said, harmful emissions are the most critical factors that have made the diesel vehicle drivers and manufacturers think about using diesel exhaust fluid. The SCR system with Adblue diesel reduces harmful emissions (NOx) and converts them into harmless ones (Nitrogen & water).
According to the World Health Organization (WHO) studies, harmful emissions can contribute to poor air quality causing 7000000 deaths every year worldwide.
Increases Efficiency of the Engine
Using Adblue fluid helps modern diesel cars eliminate the toxic emissions in the engine after combustion. So, car manufacturers can optimize the engine power and increase the period between oil changes. Diesel exhaust fuel extends your vehicles’ life and can save about 5 to 7 percent in fuel cost.
Environmentally Friendly
If you look at the DEF specifications, it is a colorless, stable, non polluting, and non-toxic solution. So, it is safe to store and handle, and it has no threat to wildlife, humans, and the environment when used correctly.
Help us to Comply with Regulations
If you want to take part in preserving the environment, you should comply with EPA regulations. The Environmental Protection Agency (EPA) is one of the United States Agencies responsible for environmental protection matters.
Does My Car Need Adblue?
Adblue fuel is a unique liquid agent that is first introduced as a way to reduce emissions levels of diesel cars to meet Euro 6 standards. So, any diesel cars manufactured on or after this date are required to comply. Otherwise, they would fail their emissions test. The modern diesel cars are fitted with a particular indicator on the dashboard that warns you when blue DEF levels are running low.
Which Car Brands Make Use of Adblue?
Some clues that help you find out whether the car you want to buy uses AdBlue fluid or not. Sometimes the word “Blue” or “SCR” are part of the car’s name. BlueHDi, EcoBlue, and TDi SCR are some badges that you can see. Look at the vehicles that use AdBlue in the table below.
| Car Brand | Models That Have Diesel Options |
|---|---|
| Audi | A5 Sportback
Q7 A4 Saloon A4 Avant A6 Avant A7 Sportback A8 Q3 Q5 |
| BMW | BMW Series 5 Saloon

Conclusion
Most of the latest diesel vehicles that meet Euro 6 emissions standards use AdBlue. This solution reduces the harmful emissions or removes toxic substances from the cars’ exhaust gasses. The emissions can seriously affect people’s health. So it is the policy that is considered for new diesel vehicles.
Azure is the best California DEF manufacturer that supplies and processes high-quality Adblue. For more information, contact us.
