Abstract

Worldwide regulations on particulate matter for passenger vehicles have become stricter in recent years, which makes it difficult to satisfy for gasoline direct injection (GDI) vehicles. In this study, the level of reduction efficiency of particle emissions with a metal-foam gasoline particulate filter (GPF) for the turbocharged GDI vehicle was evaluated in the federal test procedure (FTP)-75 mode operation. The particle number (PN) emissions were analyzed using the AVL particle counter (APC) and fast response differential mobility spectrometer (DMS500) for particle size distribution. The PN concentration from the base GDI vehicle with only TWC is 1.64 E+12 number/km (#/km), while the value of the GPF-equipped case is 5.02 E+11 #/km with 69 % filtration efficiency in the vehicle test mode. In particular, the reduction rate of small particles under 23 nm in size was strongly improved with the additional installation of the metal-foam GPF. The maximum pressure drop through the GPF reached approximately 39 mbar at the highest acceleration point of phase 1 of the FTP-75 mode. The upstream temperature of the GPF was distributed at approximately 380 ∼ 510 oC in the vehicle test. The results show that the GPF-equipped GDI vehicle can satisfy the stringent particle regulation by Euro 6 in a straightforward manner.
