Study of simple detection of gasoline fuel contaminants contributing to increase Particulate Matter Emissions
The reduction of particulate emissions is one of the most important challenges facing the development of future gasoline engines. Several studies have demonstrated the impact of fuel chemical composition on the emissions of particulate matter, more particularly, the detrimental effect of high boiling point components such as heavy aromatics. Fuel contamination is likely to become a critical issue as new, more stringent regulations such as Real Driving Emissions RDE with market fuel. The objective of this study is to investigate several experimental approaches to detect the presence of Diesel fuel in Gasoline which is likely to alter pollutant emissions. To achieve this, a fuel matrix composed of 14 fuels was built presenting diesel fuel in varying concentrations from 0.1 to 2% v/v. The fuel matrix was characterized using several original techniques developed in this study.
