Why SCR with DEF?
The advantage of using DEF is that it enables the engine to use less EGR and higher oxygen levels, offering more efficient combustion. DEF allows us to avoid the disadvantages of increasing EGR to extreme levels and meets the EPA’s requirements of near-zero NOx emissions (0.2g/hp-hr NOx). The results are maximum fuel efficiency and an emission of nitrogen and water, which are elements in the air we breathe every day.
