Diesel exhaust fluid (commonly known as: aqueous urea solution,AUS 32;called AdBlue in China and Europe, called DEF in the Americas, and called ARLA32 in Brazil. AdBlue is a high-purity transparent liquid composed of 32.5% high-purity urea and 67.5% deionized water, with a slight smell of ammonia.

If it splashes, the water evaporates and crystals form. AdBlue is used in cars, trucks, buses and heavy-duty non-road diesel engine vehicles equipped with SCR (vehicle selective catalytic reduction exhaust gas aftertreatment) system. It is a consumable that must be used in SCR technology. It will be used together with SCR catalyst. The harmful nitrogen oxides emitted by diesel engines are converted into harmless water vapor and nitrogen. The main components of the SCR system include catalyst, AdBlue injection device, AdBlue container and AdBlue dose controller.

Almost all heavy-duty vehicle manufacturers in Europe, the United States and Asia, including China, also equip their vehicles with selective catalytic reduction systems and AdBlue working fluids to meet the new nitrogen oxide emission standards (such as Euro IV, Euro 5) AdBlue and Under the combined effect of SCR technology, it can optimize engine performance and fuel consumption, reduce diesel consumption by up to 6% and significantly reduce costs. The average consumption of AdBlue is 5% of general diesel consumption, which is about 1.5 liters per 100 kilometers of highway driving.

AdBlue can only be used to configure the engine combination of the SCR system, because it is neither a fuel nor a fuel additive. AdBlue implements standards in compliance with ISO22241, DIN70070 and CEFIC regulations to ensure the effective operation of the SCR system. AdBlue is not harmful to the environment and is classified as a transportable liquid with the lowest risk.
