   Abstract : Passive NOx adsorbers (PNA) have been used for preventing NOx emissions being released during a cold start. This method involves trapping NOx on an adsorbent at low temperatures and releasing them later, when the exhaust temperature exceeds 200℃. READ MORE

4. 7. Aging of Lean NOX Trap Catalysts and Hydrocarbon Trapping in Cold-Start Applications

   Author : Rasmus Jonsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : It is well known that combustion processes worldwide give rise to emissions such as nitrogen oxides (NOX), carbon monoxide (CO), hydrocarbons (HC) and particulates. For vehicles, the method for handling these emissions has been through the development of the catalytic converter. READ MORE
