AdBlue is a colourless liquid made up of high purity urea and deionised water, and vehicles with SCR technology will have a separate tank filled with it. The first clue that your car is running low on AdBlue is that you’ll see a warning light in the instrument cluster. Only very small amounts of AdBlue are used, so a refill is a rare occurrence. A diesel Volkswagen Passat, for instance, takes about 8,000 miles to empty its 13-litre AdBlue tank. And a diesel Peugeot’s tank is refilled when it’s serviced every 12,500 miles.

Using the diesel engine fluid that meets specifications is essential because low-grade DEF will contain impurities that will harm the SCR system in your hardware, and result in it working ineffectively and allowing your engine to release harmful gases into the atmosphere. AdBlue goes into a tank underneath your car and is injected into the exhaust system to remove NOx from the exhaust gases. You can buy AdBlue in containers and many fuel stations have pumps. How does AdBlue work? The technical term for an AdBlue system is Selective Catalytic Reduction (SCR). There’s a belief that an SCR system reduces a diesel engine’s efficiency, but that isn’t the case. You can, however, help your car’s diesel engine maintain its efficiency with a diesel engine cleaner. Alternatively, or in conjunction, you can also use an injector cleaner. Does my car use AdBlue?When combined with SCR technology, AdBlue converts nitrogen oxide (NOx) emissions from Diesel engines into harmless nitrogen and water vapour non-polluting components already present in the atmosphere. IBC – Available with a range of dispensing equipment including pumps, digital flow meters and automatic shut off nozzles.

A convenient way to store AdBlue for operators with limited storage space or who only run a few vehicles that require AdBlue. Selective Catalytic Reduction (SCR) is a technique used to clean up diesel emissions. Exhaust gases can be treated with AdBlue to remove harmful pollutants, including nitrogen oxides (NOx), of which nitrogen dioxide (NO2) is the most harmful. As AdBlue is an exhaust additive, it’s used at a much slower rate than your fuel so it lasts a lot longer than the diesel in your fuel tank – around a rate of 5% AdBlue to diesel fuel is a rule of thumb worth following. AdBlue is used with diesel engines using SCR technology. This technology (Selective Catalytic Reduction) reduces harmful emissions (NOx). AdBlue is injected into the catalyst of the SCR system, where it triggers a chemical reaction with the ammonia. This chemical reaction converts the toxic nitrogen oxides (NOx) into nitrogen (N2) and water vapour (H2O). Water vapour and nitrogen are naturally occurring gases that are harmless to the environment.

Nitrogen Oxide from the engine is converted to nitrogen (a harmless gas, the main component of the air we breathe) and to water vapour, through the chemical reaction with the Ammonia in the SCR catalyst. In terms of chemical properties, AdBlue is alkaline, with a pH between 9 and 10 and has a density of 1.088g/cm 3. AdBlue that meets specifications for use in diesel engines must have a water solubility of 100g/litre and a urea content of between 31.8% and 33.2%.
