- AdBlue:<\/strong><\/li>\n<\/ul>\n
AdBlue is the trade name of a diesel engine exhaust gas treatment solution, registered by the German Automotive Industry Association (VDA). AdBlue is a solution consisting of 32.5% urea and 67.5% distilled water, playing a crucial role in reducing harmful NOx (nitrogen oxide) emissions from diesel engines, converting them into harmless nitrogen and water vapor.<\/p>\n
