Roadside remote sensing measurement was used to explore the real-world emission status of light duty gasoline vehicles (LDGVs) and motorcycles in Macao. Both fuel-based and distance-based emission factors were derived using the mass balance method. The emission concentration profile of LDGVs illustrated the benefits of tightening emission standards at the source country or region of import. The distance-based...
This paper describes the effect of fuel sulfur levels on vehicle emissions. The project was undertaken to provide a basis for lowering sulfur levels in fuel in order to establish necessary vehicle emission standards. A matrix was developed to describe the relationship between fuel sulfur levels and vehicle emissions based on vehicle testing data in China and the literature research. The matrix was...
