AdBlue® is a registered trademark of the VDA ( Verband der Automobilindustrie) that is used in Diesel cars to meet the requirements for reduction of car emissions, in combination with SCR systems to reduce the NOx emissions.
AdBlue is not a fuel or fuel additive, it is a 32.5% solution of urea in deionized water* und thus, unlike diesel, it is a clear, non-toxic liquid that is safe to handle and does not damage the environment.
* Following the ISO 22241.
How does Adblue work?
AdBlue is injected into the exhaust of the diesel engine. Due to high temperature, AdBlue® releases ammonia, which reacts in the catalytic converter with the nitrogen oxides from the exhaust gas to form harmlesharmless nitrogen and water vapor.
How is AdBlue® produced?
AdBlue® is made from urea synthesis. During the urea synthesis an approx. 70% hot urea melt is produced, which is diluted with osmosis water to a concentration of 32.5%.
How long can AdBlue® be stored?
AdBlue® can be stored for many months if stored in a cool, dark place. When stored warm or in UV light, AdBlue® decomposes slowly
