Particulate matter (PM) emissions from gasoline vehicles has recently become a subject of research and regulatory interest. New technology gasoline direct injection (GDI) engines can produce significantly higher levels of particulates than older technology port fuel injection (PFI) engines. Particulate emissions are also influenced by gasoline fuel properties and chemical composition. Differences in PM emissions may be caused by many factors including differences in the gasoline components of the fuels, engine optimization and fuel injection system optimization design. This study is a review the literature on the effects of gasoline properties, such as the distillation parameters and the Particulate Matter Index (PMI) on PM mass and particle number emissions from PFI and GDI vehicles/engines of different technologies. The literature results included journal articles, SAE technical papers, and reports by government agencies and well as collaborative industry studies, and they covered a variety of vehicle/engine configurations, driving cycles, and vehicle types. Data from the literature search were collected and compiled into a large database. Statistical analyses were then conducted to evaluate correlations between PM (mass and number) emissions and various fuel properties for select vehicle engine/technology configurations and for particular driving conditions. A key feature of this study is that in evaluate PM emissions effects over a broad range of studies, fuel specific trends that might not otherwise be identified in smaller studies can be explored.
