Diesel engines have always been a top choice for many people due to their ability to offer better mileage and more torque. However, diesel engines have also been a threat to the environment. A lot of countries even charge a hefty amount of tax on diesel cars. The toxic gases from diesel cars have been in particular focus in recent years. Manufacturers are working on ways to reduce emissions. AdBlue is one such innovation that greatly reduces the emission levels from diesel cars. In today’s article will see what AdBlue is and how it works.
What is AdBlue?
AdBlue is a liquid used to treat exhaust gases and remove harmful pollutants, including nitrogen oxides, of which nitrogen dioxide is the most harmful. AdBlue is a registered trademark owned by the German Association of the Automobile Industry.
How does it work?
The fluid is stored in a tank in the car. But unlike petrol or diesel, it is not injected into the engine; instead, it is fed into part of the vehicle’s exhaust. AdBlue is a colourless liquid made up of high purity urea and deionized water. A chemical reaction converts the harmful exhaust gases into harmless nitrogen and water.
Which cars use AdBlue?
The system is still in its development stage. So far, it is used in big, expensive diesel models as the system is too large and too expensive to squeeze into small engines.
How long does it last?
The tank that holds the solution varies in size between makes and models of cars. The rate at which it is consumed depends on the size of the car and driving style. The more economical the car and driver, the slower it will be used.
How will drivers know if AdBlue needs topping up?
The car instrument cluster should flash its tell-tale lights, like other warnings. Failing to act on these warnings will ultimately result in the car refusing to start. You can fill the AdBlue yourself if needed. Many garages and fillings stations sell portable containers of AdBlue.
AdBlue and warranty
You should use branded AdBlue solutions if your car is under warranty. For any solution to use this trademark, it must comply with certain standards that vehicle manufacturer’s SCR systems rely on. Failing to do so could invalidate the warranty.
