【Abstract】 As a consequence of increasingly stringent emissions requirements, a variety of auto-catalyst systems will be developed in the 21st century. This paper reviews TWC(Three Way Catalyst)for LEV(Low Emission Vehicle),ULEV(Ultra Low Emission vehicle) and ZLEV(Zero Emission Vehicle), TWC for lean burn engines, FWC(Four way Catalyst) for diesel engines, and catalysts for alternative fuel powered vehicles.更多还原
