AdBlue: our range
Modern diesel vehicles use AdBlue, a clear and non-toxic liquid that plays an essential role in reducing harmful emissions from diesel engines.
AdBlue is an essential colourless liquid used in diesel vehicles equipped with SCR technology. This special liquid is stored in a dedicated tank on board the vehicle.
The use of AdBlue is essential for the correct functioning of the SCR system, which aims to reduce the nitrogen oxide emissions produced by diesel engines. When the vehicle is moving, a small quantity of AdBlue is injected into the exhaust stream.
The usefulness of AdBlue in reducing pollutant emissions
Reducing nitrogen oxide emissions
The use of AdBlue in vehicles helps to reduce emissions of harmful nitrogen oxides, which are detrimental to the environment. When the motor is in use, the exhaust gases pass through a treatment system that includes the SCR (Selective Catalytic Reduction) catalytic converter, where AdBlue is injected. This chemical process converts a large proportion of nitrogen oxides into nitrogen and water, significantly reducing their environmental impact.
Impact of AdBlue on vehicle performance
The use of AdBlue in SCR systems enables diesel motor performance to be maintained while complying with strict environmental standards on pollutant emissions. The use of AdBlue has little or no impact on fuel consumption. In fact, in some cases, it can slightly improve energy efficiency by allowing the motor to run at optimum temperature.
- Fewer pollutants: AdBlue makes a significant contribution to reducing NOx emissions, one of the main pollutants produced by diesel vehicles.
- Compliance with standards: By using AdBlue, diesel vehicle manufacturers can meet increasingly stringent regulatory requirements in terms of emissions.
- Performance maintained: The addition of AdBlue does not compromise engine performance, ensuring that power and efficiency remain intact.
Compliance with strict environmental standards
One of the main advantages of using AdBlue is its ability to help diesel vehicles comply with strict environmental emissions standards. Euro 6 european regulations impose a strict limit on carmakers’ emissions of particulates and nitrous oxides from catalytic converters.
Regular use of this product ensures that the particulate filter and SCR system work effectively to keep these emissions under control. Not only does this directly benefit our immediate environment by reducing air pollution, it also enables drivers to comply fully with emissions legislation.

Understanding how the SCR system works
The key components of the SCR system
The Selective Catalytic Reduction (SCR) system plays a crucial role in reducing the nitrogen oxides (NOx) emitted by diesel vehicles. This system comprises several key elements:
The SCR reactor, where the chemical reaction takes place.
An AdBlue injector, which sprays the solution into the exhaust stream.
The SCR catalyst, which accelerates the reaction without participating chemically.
Finally, a control system that regulates the flow of AdBlue.
The NOx conversion process with AdBlue
When AdBlue is injected into the exhaust gases, a series of reactions take place. At high temperatures, AdBlue breaks down into ammonia (NH3) and carbon dioxide (CO2). Ammonia, the active component in the reaction, then comes into contact with the nitrogen oxides in the exhaust gases in the SCR catalyst. This interaction transforms harmful NOx into nitrogen (N2) and water vapour (H2O), two compounds that are harmless to the environment.
Interaction between urea and exhaust gases
The key to the SCR system resides in the ability of AdBlue, a urea-based solution, to react with the hot exhaust gases before reaching the SCR catalyst. This crucial interaction enables NOx to be converted efficiently while ensuring that the diesel motor runs efficiently. Moreover, the electronic control system ensures precise AdBlue dosage, which is essential to maintain the efficiency of the pollution control process and avoid over-consumption of the solution.

Frequently asked questions about AdBlue
What exactly is AdBlue?
How can I check my vehicle's AdBlue level?
Most vehicles fitted with an SCR system have an AdBlue level indicator on the dashboard. Consult your vehicle owner’s manual for specific instruction
How often should I refill the AdBlue tank?
This depends on your vehicle model and your driving style. Usually, you need to fill up with AdBlue every 10,000 to 20,000 kilometres or around.
