Warning to drivers of diesel cars over need for AdBlue
Published 16/03/2016 | 02:30
The arrival of a new product on the Irish 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 Topaz which will be sold across its 340-plus service stations.
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.
Jack Condon of Topaz warns, however, that many people don't realise their new diesels require the product.
He says: "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."
He says his company worked with car manufacturers to make the off-the-shelf new product and claims the spill-proof bottle and nozzle make topping-up simple. The 1.89-litre product costs €12.99.
