Abstract
Low fuel consumption and improved power output are the main market drivers in the automotive industry. For these challenges, Gasoline Direct Injection (GDI) technology provides higher thermal efficiency than Multi Point Injection (MPI) engines and this technology is expanding as a solution to reduce CO₂ and improve driveability. In Europe under the Euro 5 regulation, engine downsizing becomes a major solution to reduce CO₂ of gasoline engines. For this concept GDI is essential together with turbocharging technology. However GDI technology increases particulate matter (PM) emissions compared to MPI engines. As the introduction of a Particle Number (PN) regulation for Euro 6 GDI vehicles has been decided, technologies to reduce GDI PN emissions start to become necessary. For this requirement, a gasoline particulate filter (GPF) is an effective solution. The basic concept of a GPF and cell structure optimization for lower pressure drop was presented by SAE 2011-01-0814 and SAE 2012-01-1241. This paper will describe the development status of advanced GPF for uncoated and coated concepts, which can reduce pressure drop even further.
