    AI Overview
    AdBlue® 40% (also known as AUS40) is a specialized marine-grade urea solution composed of 40% urea and 60% demineralized water. It is used specifically in large marine diesel engines with Selective Catalytic Reduction (SCR) technology to significantly reduce NOx emissions. 
    Key Aspects of AUS40 (AdBlue 40%): 
    • Application: Exclusively designed for high-power marine vessels, such as shipping cargo ships and cruise ships.
    • Higher Concentration: Unlike automotive AdBlue (AUS32), which is 32.5%, this 40% formulation is better suited for large-scale marine engines.
    • Emission Compliance: Ensures compliance with strict nitrogen oxide (NOx) emission regulations, often achieving near-zero levels
      .
    • Storage: Needs to be stored in specialized stainless steel or plastic tanks, often on a large scale (e.g., 1000L tanks).
    • Operation: Acts as a reduction agent, transforming harmful nitrogen oxides (NOx) into nitrogen and water vapor. 
    Do not use 40% urea solution in passenger cars or heavy-duty trucks that require 32.5% (AUS32/AdBlue), as this can damage the SCR system.

    What does AdBlue do for your engine?
    AdBlue® is a colourless, non-toxic liquid that is a solution of water and urea. It works to convert nitrogen oxide emissions in the exhaust gas of diesel engines, into nitrogen and water. A particulate filter then further reduces solid particulates from the vehicle's exhaust emissions.

    How low is too low for AdBlue?
    When AdBlue level is low, you may see a warning light resembling a bottle with pouring liquid or something similar. This warning light indicates that you have about 3 litres left, enough for approximately 1,500 miles so it's best to fill up as soon as possible.
