    AI Overview
    AUS 32 (Aqueous Urea Solution 32.5%) is a high-purity solution of 32.5% urea and 67.5% demineralized water, commonly known as AdBlue or Diesel Exhaust Fluid (DEF). It is used in Selective Catalytic Reduction (SCR) systems to convert harmful nitrogen oxides (NOx) from diesel engine exhaust into nitrogen and water. 
    Key Details About AUS 32: 
    • Composition: 32.5% industrial urea and 67.5% deionized water.
    • Purpose: Essential for reducing nitrogen oxide emissions in diesel cars, trucks, tractors, and machinery to meet Euro 4, 5, and 6 standards.
    • Operation: Injected into the exhaust pipe, where it turns into ammonia, reacting with the catalyst to reduce NOx.
    • Freezing/Boiling Points: Freezes at

      −11.5∘C

       to avoid crystallization or degradation.
    • Standardization: Manufactured according to ISO 22241 standards. 
    Common Usage:
    AUS 32 is injected at a rate of 3% to 5% of diesel fuel consumption. It is non-toxic and biodegradable but can be corrosive to some metals.

    How to make 32.5 urea solution?
    o Take 67.5% deionized water in a stainless steel mixing tank. o Heat the water to 40–50°C to help dissolve the urea faster. o Gradually add 32.5% high-purity urea into the heated water while stirring. o Ensure the urea is completely dissolved to form a clear solution. o Maintain a pH of 9.0–10.0 during mixing.

    Can I use pee instead of DEF?
    An error has occurred. Please try again later.
    Can I just use water instead of AdBlue?
    If you add water instead of AdBlue®, it can potentially be extremely damaging and expensive. This is because water can block your car's AdBlue® injector, negatively affect the catalyst and ultimately cause the SCR (Selective Catalytic Reduction) system to fail, which can stop your engine from functioning.
