It began with the implementation of exhaust gas recirculation (EGR) systems, then progressed to the diesel particulate filter (DPF), and now the buzz is around selective catalytic reduction (SCR). Selective catalytic reduction systems use a consumable diesel exhaust fluid (DEF) in conjunction with a catalyst to reduce nitrous oxide (NOx) emissions. Because the fluid is consumed during the system’s normal operation, it requires the vehicles owner to not only monitor the fluids level but also refill it when it’s been used up. In the past, we’ve explained how and why all these new emissions control systems work, and now—with the use of SCR becoming widespread—we’re going to look a little closer at the fluid you’re likely to soon be buying.
