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 hea...

What is SCR technology? "SCR" is the abbreviation of Selective Catalytic Reduction Technology, which is a technology used for the after-treatment of diesel vehicle exhaust to reduce harmful nitrogen oxide emissions from vehicles. The reducing agent used in the SCR technology is vehicle urea solution. Almost all major engine manufacturers need to use this technology to meet the emission requirement...

Aqueous urea solutions AUS 40, AUS 32 are NOx reducing agents. Aqueous urea solution AUS 32 reduces nitrogen oxide emission from auto exhaust system. The solution is injected to diesel engine exhaust systems before selective reduction catalyst, consequently due to the solution reaction with nitrogen oxide gasses emissions are converted to water vapour and nitrogen. This technology o...

How to Distinguish Between Qualified and Unqualified Urea Solution The concentration of the urea solution is one of the key factors. The concentration of urea solution directly affects the catalytic efficiency of NOx and the freezing point of the urea solution, and also affects the parameter setting of the aftertreatment system. The concentration of the high-quality automotive urea solution must b...

AdBlue® is used in cars, trucks, buses and heavy-duty non-road use 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 nitr...

Current Situation of the domestic market: During the use of National IV diesel vehicles, AdBlue consumption is 3% to 5% of the fuel consumption. Each heavy-duty truck of National IV standard consumes about 2 tons of vehicle urea per year. Although China's automotive AdBlue consumption was about 11,000 tons in 2011, it only accounted for 1% of the world's automotive urea solution consumption....

1. Shield the vicious circle caused by the SCR system Blocking the work of the scr system will leave the nozzle in a helpless situation and can only wait in a high temperature environment. Urea pumps and pipelines that have not been operated for a long time will crystallize and block due to the evaporation of the remaining liquid moisture. 2. No regular replacement If dust is accidentally brought ...

1.Background of AdBlue In recent years, haze pollution has occurred in many places in my country, and motor vehicle exhaust emissions account for an average of 20% to 25% of the cause of haze weather. The annual national motor vehicle emissions reach 57 million tons, including nitrogen oxides, monoxide and particulate matter, of which nitrogen oxides and particulate matter emitted by automobiles e...

Is def adblue dangerous? No, it’s non-toxic and non-flammable. But don’t drink it! If the fluid come into contact with eyes, flush them with plenty of water and seek medical attention. Clean affected skin with soap and water. If swallowed, drink plenty of water and seek medical attention immediately. When removing the tank cap or a container cap, ammonia vapour may escape. Ammonia vapour is a...

Types and hazards of AdBlue Crystallization 1. The crystallization from the exhaust pipe and nozzle: it is not easy to clean, and the inside of the exhaust pipe has been deteriorated after high temperature, the texture is tough. (Easily found with an endoscope) Hazard: Increased exhaust resistance causes abnormal operation of the aftertreatment system. 2. Crystallization inside the urea pump and p...
