Federal Test Procedure (FTP) emissions were measured on a 4 cylinder 2.4L Malibu PZEV vehicle with 10 and 30ppm sulfur fuel while varying the PGM (Platinum Group Metals) of the close-coupled and under floor converters. Base CARB PH-III certification fuel was used. Three consecutive FTP’s were used to measure the impact of fuel sulfur and catalyst PGM loading combinations. In general, reducing fuel sulfur and increasing catalyst PGM loadings decreased FTP emissions. It is estimated that a fuel sulfur change from 30 to 10 ppm may save $100 in catalyst system PGM.
