AdBlue has become an essential product by regulation in diesel vehicles. It is a key element that helps reduce emissions and improve engine performance.
The latest emission regulations have caused the need to devise different ways to reduce polluting gases, especially from diesel vehicles. One of these solutions that have been standardized and that is present in many vehicles is the use of selective catalytic reduction devices, more commonly known as AdBlue.
It is a compound that helps reduce polluting products derived from engine combustion. It is a liquid that does not pollute the environment, colorless, odorless and is not flammable or toxic, since it is made up of deionized water with 32.5% urea. The addition of AdBlue can only be done in diesel vehicles. In them we have, next to the entrance of the fuel tank, an opening to fill the tank, exclusively for AdBlue.
Diesel engines generate less amount of polluting products and CO2, but the same does not happen with nitrogen oxides (NOx) and benzopyrenes present in the ash generated by the combustion of diesel.
As explained from Green Chem , in the SCR catalyst a series of reactions take place. AdBlue fluid is injected and reacting with catalyst elements and NOx particles results in a 90% reduction in NOx reaching the exhaust duct. After this reaction, the only particles that are emitted are nitrogen, water and carbon dioxide (N2, H2O and some CO2).
What arose as a measure to be able to comply with the European regulations on nitrogen oxides has become a problem for the owners of some vehicles, who have come to report the appearance of an error in the system and warn them that they must fix it. to continue using it.
Its repair can involve a cost of 1,200 euros for the owners, who have coordinated to try to get the manufacturers of the affected vehicles and brands to assume the cost of the repair, which implies the replacement of said deposit without the guarantee that, Years later, I have the same problem again.
According to specialists from oscaro its relevance within the gear of the current vehicle is such that even its low quality or lack of quantity of liquid can lead to engine failure. Normally, the tank is emptied close to the official maintenance dates, but depending on the use and kilometers this can vary. In the case of running out of product, the car will not start, preventing movement until the tank is refilled.
However, it is important to note that if this happens with the vehicle running, the engine will not stop, but once it stops it will not start again until the AdBlue tank is filled. Hence, the importance of being attentive to the levels so that it does not play a trick on us.
Another of the main doubts that arise is given by the need to know if some type of maintenance of this liquid must be carried out. First of all, it is important to know that AdBlue runs out over the kilometers. Consumption in diesel cars usually varies depending on the model, but the average cost ranges between 1.5l and 3l per 1,000km. In this sense, Oscaro experts indicate that the AdBlue tank must be filled between 5,000 and 20,000 km, depending on the car model.
When it comes to refueling, the general trend is to acquire drums of this liquid to do it manually. Filling the AdBlue tank is usually quite simple, especially in the most recent models, since they usually have access to the tank in blue next to the access to the diesel tank. In older cars, access to it is usually more complicated as it is in the trunk or next to the car engine. On the other hand, there is also the possibility of “refueling” at some gas stations (although it is not yet a widespread trend), as well as in the manufacturer’s technical service.
