Gasoline Engine Particulate Emission and Exhaust Gas Speciation

This study attempted to identify the correlation between the gaseous species and nano-scale exhaust particles from a gasoline engine using simultaneous particulate and gaseous measurement. A fast particle spectrometer for particulates and a quadrupole mass spectrometer for gaseous species were employed in this work. Two commercially available super unleaded gasoline fuels were used in this study to establish a link between the gaseous species and nano-scale particulates. The possible correlations between the gaseous species such as acetylene, 1, 5 hexadyne, toluene, benzene and furaldehyde and nano-scale particles were identified and are detailed in this paper.
