This product is a solution composed of 32.5% high-purity urea and 67.5% demineralized water, which is injected into the exhaust gases of a diesel engine. What is AdBlue used for? Simple: it helps to reduce NOx emissions in combination with SCR technology. Therefore, AdBlue is a diesel additive that must be used for all Euro 6 diesel engines. It is atomized through the injector located in the exhaust system and at high temperatures, it transforms into carbon dioxide and ammonia. The additive must be poured into a separate tank. If the liquid runs out, the engine cannot be started, and the same consequence will occur if the diesel additive is added to the fuel tank.
As for the consumption of AdBlue, it depends on numerous factors, not least the driving style adopted. Generally, it is believed that the consumption of AdBlue is equivalent to 500Km/l and that the dedicated tank can hold an amount ranging from 11 to 19 liters. To find out where to locate the AdBlue tank, one should check the vehicle's instruction manual, but it is good to know that the cap for this element is blue. Always use a new funnel!
