Cobra DEF is a 32.5% aqueous urea solution, AUS 32, a manufactured product of technically pure urea mixed with deionized water designed to meet the specifications of ISO 22241-1:2019 for NOx abatement technologies. Cobra DEF is certified as a Diesel Exhaust Fluid by the American Petroleum Institute.
DEF is not a fuel additive; instead, it is a precise mixture of urea and deionized water that is sprayed into the exhaust gas before entering the diesel engine’s SCR catalyst. Through a chemical reaction, the DEF helps break down the nitrogen oxides (NOx) generated by the exhaust system into environment-friendly nitrogen, water vapor, and ...
