AdBlue, also known as Diesel Exhaust Fluid (DEF), is a clear, colorless liquid that plays a vital role in reducing harmful emissions from diesel engines. It’s a non-toxic, non-flammable urea-based solution that works in conjunction with Selective Catalytic Reduction (SCR) technology to convert harmful nitrogen oxides (NOx) into harmless nitrogen and water vapor.
How AdBlue Works
The SCR system is a complex piece of equipment that is integrated into the exhaust system of modern diesel engines. It consists of a catalyst bed and a dosing system that injects AdBlue into the exhaust stream. When AdBlue comes into contact with the hot exhaust gases, it vaporizes and decomposes into ammonia. The ammonia then reacts with the NOx in the exhaust gases over the surface of the catalyst, reducing them to nitrogen and water.
The Importance of AdBlue
AdBlue is essential for meeting the stringent emission standards that have been implemented in many countries around the world. Without AdBlue, diesel engines would not be able to comply with these regulations. This is particularly important for commercial vehicles, such as trucks and buses, which are often subject to stricter emission controls.
AdBlue Storage and Handling
AdBlue is typically stored in a separate tank on the vehicle or in a refillable container. It is important to keep AdBlue away from heat sources and direct sunlight, as this can cause it to degrade. Additionally, AdBlue should not be mixed with other fluids, such as diesel fuel or water.
AdBlue Consumption
The rate at which AdBlue is consumed varies depending on several factors, including the type of engine, driving conditions, and the load on the vehicle. However, it is generally expected that AdBlue consumption will be around 2-5% of the total fuel consumption.

How Diesel Particulate Filters Work
A DPF is a ceramic filter that is installed in the exhaust system of a diesel engine. In the filter, particulate matter is caught in the pores when exhaust gases flow past it. The trapped particles are then periodically burned off in a process known as regeneration. During regeneration, the temperature of the exhaust gases is increased to ignite the trapped particles, converting them into harmless gases.
The Relationship Between AdBlue and DPFs
AdBlue and DPFs work together to reduce emissions from diesel engines. The AdBlue SCR system helps to reduce NOx emissions, which can contribute to the formation of particulate matter. By reducing NOx, AdBlue can help to improve the performance of the DPF and reduce the frequency of regenerations.
DPF Regeneration and AdBlue
The frequency of DPF regenerations can be affected by several factors, including driving conditions, the type of engine, and the quality of the diesel fuel. AdBlue can help to reduce the frequency of regenerations by reducing the amount of particulate matter that is trapped in the DPF.
AdBlue and DPF Maintenance
Both AdBlue and DPFs require regular maintenance to ensure optimal performance. AdBlue tanks should be refilled as needed, and DPFs should be inspected and cleaned periodically. It is also important to use high-quality diesel fuel to avoid clogging the DPF.
AdBlue and DPF Cleaning
If a DPF becomes clogged, it may need to be cleaned or replaced. AdBlue can help to prevent DPF clogging by reducing the amount of particulate matter that is trapped in the filter. However, if a DPF becomes severely clogged, it may need to be cleaned or replaced by a professional mechanic.
AdBlue and DPF Issues
There are several issues that can arise with AdBlue and DPF systems. These issues can include:
AdBlue tank leaks: These leaks may result in a decrease in the AdBlue level, which may impact the SCR system’s functionality.
DPF clogging: DPFs can become clogged with particulate matter, which can reduce engine performance and increase fuel consumption.
AdBlue FAQs
The following are some of the most common enquiries concerning AdBlue:
Does AdBlue have negative environmental effects?
AdBlue does not pose a threat to the environment. Actually, it’s employed to cut down on dangerous emissions from diesel engines.
Can I use AdBlue instead of diesel fuel?
No, AdBlue is not a fuel. It is a separate fluid that is used in conjunction with diesel fuel to reduce emissions.
How frequently should my AdBlue tank be refilled?
The frequency with which you need to refill your AdBlue tank will depend on your driving habits and the size of your tank. However, it is generally recommended to check your AdBlue level regularly and refill it as needed.
Can I add water to my AdBlue tank?
No, you should not add water to your AdBlue tank. This can dilute the AdBlue and reduce its effectiveness.
What happens if I run out of AdBlue?
If you run out of AdBlue, your vehicle’s engine will go into a limp mode to protect itself from damage. You will need to refuel your AdBlue tank before you can continue driving.
In conclusion, AdBlue is a crucial component of modern diesel engines that is essential for meeting stringent emission standards. By using AdBlue, drivers can help to reduce air pollution and protect the environment. Screwfix is a reliable source for AdBlue, offering a wide range of products at competitive prices.
