    AI Overview
    AUS40 (Aqueous Urea Solution 40%) is a 40% urea concentration fluid used for Selective Catalytic Reduction (SCR) systems in large marine engines and ships to reduce NOx emissions. Unlike standard automotive AdBlue (32.5%), AUS40 is specially designed for heavy-duty marine engines, complying with ISO 18611 standards to improve efficiency and reduce clogging in high-load conditions. 
    Key Aspects of AUS40 (40% Urea Solution): 
    • Application: Primarily for large cargo ships, marine vessels, and occasionally large industrial diesel engines, according to.
    • Composition: 40% high-purity urea and 60% deionized water, which allows for smaller storage tanks on vessels compared to using 32.5% solutions
      .
    • Purpose: Converts nitrogen oxides (
      NOxcap N cap O sub x
      𝑁𝑂𝑥
      ) into harmless nitrogen (
      N2cap N sub 2
      𝑁2
      ) and water vapor (
      H2Ocap H sub 2 cap O
      𝐻2𝑂
      ) in marine engines.
    • Standard: Manufactured to comply with ISO 18611-1:2014, distinct from automotive AdBlue which follows ISO 22241.
    • Benefits: Reduces
      NOxcap N cap O sub x
      𝑁𝑂𝑥
       emissions to near-zero levels, ensures compliance with strict marine environmental regulations, and optimizes engine performance.
    • Safety: The fluid is non-hazardous and non-toxic, though it requires proper handling to avoid skin or eye irritation, note. 
    AUS40 vs. Standard AdBlue (32.5%)
    While both act as reduction agents, they are not interchangeable. Standard AdBlue (32.5%) is for passenger cars and trucks, while AUS40 (40%) is tailored for the higher exhaust temperatures and power output of marine engines.

    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.
