A state-of-art FCC technology has been strongly requested in order to achieve the most stringent emission requirement like PZEV. Appropriate TWC system, which is applicable for the reduction of both LOT and LOt should be established for this solution. In this paper GMK’s recent advanced calculation program (AU-53), which can offer more specific calculation including durability and poisoning effect than current program(AU-85), showed a good correlation with current ULEVII system. This can be extended to apply to PZEV especially predicting in LOt behavior during warm up condition. In this improved program cold start region can be also divided into three areas which have own characteristics regarding temperature profiles set by each RPM, A/F and even PGM’s combustion energy. In calculating catalyst oxidation and internal combustion energy we assumed more specific components rather propane as a model gas following ideal gas behavior in NMOG. This new programing achieved well correlation with SULEV vehicle rather ULEV applied to old Programming (AU-85). Lots of factors for AU-53 were requested in order to correlate test result as input data like engine RPM, A/F, engine displacement, catalyst loading, ratio and even cell density as was used same in AU-85. Consequently by combined major variables comprising of catalyst design we could take on appropriate LOt figures. Here in cold start research we can introduce significantly advanced programming technology comparing to conventional method. Optimized configuration of FCC system could be proposed in cost and performance including PGM loading, ratio and cell density
