    AI Overview
    AUS 32 (Aqueous Urea Solution 32.5%) is a high-purity, 32.5% urea and 67.5% deionized water solution used to reduce NOx emissions in diesel vehicles equipped with Selective Catalytic Reduction (SCR) systems. Commonly known as AdBlue in Europe and Diesel Exhaust Fluid (DEF) in North America, it breaks down NOx into nitrogen and water. 
    Key Facts About AUS 32 / AdBlue 
    • Composition: 32.5% high-purity urea, 67.5% deionized water.
    • Purpose: Essential for Euro 5/6 and modern diesel engines to meet emission standards.
    • Storage: Must be stored in a dedicated, separate tank, not in the fuel tank.
    • Usage: Consumption is roughly 3-5% of diesel fuel consumption.
    • Freezing Point: Starts to freeze at
      -11.5∘Cnegative 11.5 raised to the composed with power C
      −11.5∘C
       (
      11.3∘F11.3 raised to the composed with power F
      11.3∘F
      ).
    • Standards: Manufactured according to ISO 22241 standards. 
    Usage & Maintenance 
    • Refilling: It is injected into the exhaust stream before the catalyst.
    • Checking Quality: Refractometers (like the AD-2) are used to measure the 32.5% concentration to ensure the fluid is not diluted or expired.
    • Handling: Non-toxic, but should be handled carefully to avoid damaging equipment, as it can be corrosive to certain metals.
