Diesel exhaust fluid - Wikipedia

Diesel exhaust fluid (DEF; also known as AUS 32 and marketed as AdBlue) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water.DEF is consumed in selective alytic reduction (SCR) that lowers the concentration of nitrogen oxides (NO x) in the diesel exhaust emissions from

The diesel particulate filter explained | AutoGuru

15/04/2021· The filter is designed to deliver an 80% reduction in diesel particulate and soot emissions and does this by trapping the particles in the filter itself. The engine control unit (ECU) monitors the saturation level inside the filter, and when it reaches a certain percentage, increases the temperature inside the exhaust to ‘burn off’ the particles.
