Five Years Trend of Global Market Gasoline Quality Review using Fuel Particulate Emission Correlation Indices
Gasoline soot tendency has been extensively studied in last five years. Many tools has been developed to provide indications of a fuel’s sooting tendency. While some methods still have room for improvement, the tools can be used to qualitatively assess the fuel quality in markets. This paper will review the most recently developed methods, with good correlation agreement to vehicle particular emission tendency, that could be used to give indication of the sooting tendency of the gasoline range fuels, and last five years market trend as indexed by those tools. In addition, the paper will review and propose improvement of the methods on assessment of a gasoline range fuel’s sooting tendency. Areas around the globe where market gasoline range fuels are of concern will be highlighted, in coordination with the new emissions regulations.
