What is the Diesel Exhaust Fluid?

Diesel exhaust fluid (DEF) is a mixture of 67.5% deionized water and 32.5% urea. It is colorless, odorless, and non-flammable. DEF's quality is preserved in special storage tanks made of stainless steel or polyethylene plastic because the shelf life of the substance depends on the temperature at which it is stored. To reduce diesel exhaust emissions, selective catalytic reduction (SCR) uses AUS 32 as a consumable to lower nitrous oxide (NOx) levels in engines.

Impact of AI on the Diesel Exhaust Fluid Market

Artificial Intelligence (AI) is substantially influencing market-driven analytics, and ML algorithms are improving the accuracy of diesel exhaust fluid dosage and enhancing the efficiency of exhaust systems. Furthermore, automation in the diesel exhaust fluid market technology has led to reduced operational costs and higher production rates. As AI and automation evolve, their integration into diesel exhaust fluid systems is anticipated to further stimulate fuel consumption and emission control.
