Title: Fuel-Neutral Studies of PM Transportation Emissions

Abstract

New gasoline engine technologies such as Spark Ignition Direct Injection (SIDI), Gasoline Direct Injection Compression Ignition (GDICI), and Reaction Controlled Compression Ignition (RCCI) offer the possibility of dramatically increasing the fuel efficiency of future vehicles. One drawback to these advanced engines is that they have the potential to produce higher levels of exhaust particulates than current Port Fuel Injection (PFI) engines. Regulation of engine particulate emissions in Europe is moving from mass-based standards toward number-based standards. Due to growing health concerns surrounding nano-aerosols, it is likely that similar standards will eventually be applied in the United States. This would place more emphasis on the reliable removal of smaller particles, which make up the vast majority of the particulates generated on a number basis. While Diesel Particulate Filters (DPF) have become standard, different filter systems would likely be required for advanced gasoline vehicles, due to factors such as differing particulate properties and higher exhaust temperatures. High exhaust temperatures can limit the accumulation of a soot cake, which performs most of the actual filtration in a typical DPF system.
