Three way catalyst(TWC) can reduce emission in LPG engine exhaust without complex constructions. When old vehicle"s TWC was driven long odometer or worn out, it will cause deterioration of conversion efficiency. But replacing an old vehicle"s catalytic convertor are still problem too high cost. In this research, the TWC effect for exhaust gas reduction efficiency over low precious metal catalyst was tested as CVS-75 mode.

TWC(Three-Way Catalyst) was synthesized by controlling trace precious metal and coated on ceramic monolith substrate using conventional method. Especially, synthesized TWC consists of simple catalyst system. differently from conventional scheme. It means that we use two or three trace precious metal. The catalyst is analyzed by FT-IR for catalytic activity of CO, NO and C₃H?. As the result, light-off of each detrimental gas shows the good activity.
