Description
  • Economical diesel and advanced gasoline (lean-burn) engines are operated with excess of air in fuel mixture (=lean mixture), which results in high O2 concentrations in exhaust gas and complicated NOx abatement. In the NOx storage and reduction catalyst, the NOx are adsorbed on the catalyst surface during a longer lean phase (several minutes), and then reduced during a short rich phase with excess of reducing agents CO, H2 and HC (several seconds). Possible products of the NOx reduction are nitrogen (N2), ammonia (NH3) and nitrous oxide (N2O, usually minor amount). The presented laboratory experiments deal with the dynamic behaviour of periodically operated industrial PtRh/BaO/CeO2/γ-Al2O3 based catalyst. The measurements investigate the influence of temperature, inlet gas composition and timing of the lean/rich switching on the NOx reduction dynamics, product selectivity, and integral NOx conversion
