The arrival of a new product on the market is being used as a reminder to many drivers of diesel cars that they may need to check out, or improve their knowledge of, one area in particular.The product is the own-brand AdBlue from Kleas.But lots of people are a bit in the dark about what AdBlue is, what it does - and what they are supposed to do with it.
Many new diesel cars now have to have what they call SCR technology (Selective Catalytic Reduction). It is part of an emissions control that injects a liquid (AdBlue) through a special catalyst into the exhaust stream of a diesel engine. Usually this is automotive-grade urea (also known as Diesel Exhaust Fluid or DEF). The DEF sets off a chemical reaction that converts nitrogen oxides into nitrogen, water and tiny amounts of carbon dioxide (CO2). In effect it breaks down and cleans up emissions.
On cars, AdBlue filling points are smaller than, but often beside, those for fuel.Some experts reckon older diesel engines save 5pc to 7pc on fuel because of SCR technology.If a driver chooses to ignore the AdBlue warning light on their dashboard their car will slow down and ultimately stop when it runs out.
