As a result of WNTE regulations and the introduction of close-coupled aftertreatment systems, exhaust purification at high temperatures in commercial vehicles has become increasingly important in rece....
Achieving cleaner air throughout the world requires reducing diesel emissions. Therefore, after-treatment system without using a urea solution (DEF) called DPR-II has been developed in-house. It uses ....
With the push towards more stringent on-road US heavy duty diesel regulations (i.e. HD GHG Phase 2 and the proposed ARB 20 mg/bhp-hr NOx), emission system packaging has grown critical while improving ....
Meeting Euro 6d NOx emission regulations lower than 80 mg/km for light duty diesel (60 mg/km gasoline) vehicles remains a challenge, especially during cold-start tests at which the selective catalyst ....
Achieving high NOx conversion at low-temperature (T ≤ 200 °C) is a topic of active research due to potential reductions in regulated NOx emissions from diesel engines. At these temperatures, ammonium ....
Sustained NOx reduction at low temperatures, especially in the 150-200 °C range, shares some similarities with the more commonly discussed cold-start challenge, however, poses a number of additional a....
