Assessment of the Fuel Composition Impact on Black Carbon Mass, Particle Number Size Distributions, Solid Particle Number, Organic Materials, and Regulated Gaseous Emissions from a Light-Duty Gasoline Direct Injection Truck and Passenger Car (original) (raw)

This study investigates the impact of fuel composition on black carbon emissions, particle number size distributions, and regulated gaseous emissions from light-duty gasoline direct injection vehicles, including trucks and passenger cars. Utilizing metrics such as the Particulate Matter Index and the Threshold Soot Index, various laboratory methodologies were employed to obtain comprehensive measurements of particulate emissions and associated chemical properties. The findings demonstrate significant variability in emissions profiles correlating with different fuel compositions, indicating that optimizing fuel can substantially mitigate particulate emissions.
