AdBlue With team London sOuth east

All you need to know about AdBlue

AdBlue® is a soluble colourless solution that looks like water or windscreen washer fluid. It is composed of 67.5% distilled water and 32.5% high grade urea, such as that used to manufacture plastics, cosmetic products or fertilisers. Urea used as a synthetic product is typically produced from natural gas. The composition of AdBlue® makes it a biodegradable, non-explosive, non-toxic and non-flammable liquid. This liquid reduces the carbon footprint of your car and is used in many vehicles.

AdBlue®, fluid, is stored in a tank (like diesel fuel), however, unlike fuel it is not injected into the engine, but directly into a specially modified part of the vehicle’s exhaust. This begins a chemical reaction which removes the polluting oxides of nitrogen (NOx), converting them into harmless water and nitrogen in a process known as Selective Catalytic Reduction, or SCR for short. SCR is only applicable to diesel engines and the more economically you drive, typically, the less AdBlue® you will use. The size of the AdBlue® tank fitted to a vehicle will vary depending on which model it is, therefore the interval between top-ups will vary. In addition, many factors such as mileage, journey type, driving style and environmental conditions can influence how much AdBlue® is consumed. A passenger car can consume approximately 1.5 litres of AdBlue® every 620 miles (1.0–1.5 litres for the VW Passat and Passat Estate) for example.

Time to Refill.......
A series of warnings will be given via the driver information system, accompanied by advice/messages.

The first message is displayed when the remaining range is approximately 1,500 miles, and is repeated every 62 miles until the range reaches 1,000 miles, at which point the warning turns amber. This warning is repeated every 31 miles and is accompanied by an audible tone. If these warnings are not acted upon, the warning turns red; once this happens the car will not restart once the ignition is turned off. This is not a fault, but a required feature of the system. If this stage is reached the system will need a full top-up before the car can be restarted. Further information is available in the vehicle handbook.

AdBlue® is used by modern SCR (Selective catalytic reduction) systems as a way to help reduce the emissions of nitrogen oxides of your car. Since 2005 European standards have aimed to reduce the emission of pollutants from diesel cars by imposing limits for the emission of nitrogen oxides. The European standard Euro VI in force since September 2014 has reinforced these limits in order to reduce the impact on the environment of pollution produced by diesel vehicles. Many car manufacturers have since chosen to equip their cars with the SCR system, which is a technology of post combustion exhaust processing that converts the harmful molecules of nitrogen oxides in a catalyst and allows the reduction of the level of pollution of diesel cars! In this way AdBlue® powers this SCR system by circulating in an independent tank to that of the diesel. Most manufacturers have adopted this technology. Renault, Peugeot, Citroen, Mercedes-Benz, Opel, etc.
