Summary:

The gasoline particulate filter (GPF) represents a practical solution for particulate emissions control in light-duty gasoline-fueled vehicles. It is also seen as an essential technology in North America to meet the upcoming US EPA tailpipe emission regulation, as proposed in the "Multi-pollutant Rule for Model Year 2027".The goal of this study was to introduce advanced, uncoated GPF products and measure their particulate mass (PM) reduction performance within the existing US EPA FTP vehicle testing procedures, as detailed in Code of Federal Regulations (CFR) part 1066.Various state-of-the-art GPF products were characterized for their microstructure properties with lab-bench checks for pressure drop and filtration efficiency, then pre-conditioned with an EPA-recommended 1500 mile on-road break-in, and finally were tested on an AWD vehicle chassis-dyno emissions test cell at both 25°C and -7°C ambient conditions. A modern, T3B70, GTDI light-duty truck served as the test vehicle platform for this study.This report will show that advanced uncoated GPFs can repeatedly demonstrate high PM filtration efficiency, positioning them well as one solution to meet the US EPA proposed 0.5 mg/mile PM limit.
