| Abstract: | "Two diesel buses respectively certified to meet China ?a= and China ?a▒ emission standards were used as prototype vehicles, fixed on a heavy-duty chassis dynamometer and driven according to a typical city bus driving cycle to analyze the pollutant emissions and volatile organic compounds (VOCs). The buses were fueled with diesel and waste cooking oil based biodiesel with 10 vol% blend ratio (B10). The emissions of total hydrocarbon(THC), CO, particulate matter (PM), and the number of solid particles with a diameter of 23 nm to 2.5 mum (referred to as 'solid particulate number of PM(2.5)') from the bus certified to meet China ?a▒ (referred to as 'China V bus') were 39.3%, 19.9%, 77.4%, and 28.4% lower than those from the other bus certified to meet China ?a= (referred to as 'China ?a= bus'), while NO(x) emissions were 31.7% higher. Moreover, alkanes, alkenes, aromatic hydrocarbons, and oxygenated compounds in VOCs emitted from the China V bus were lower than those emitted from the China ?a= bus, suggesting lower atmospheric reactivity and smaller potential of secondary organic aerosol formation. Compared with the emission results of two diesel-fueled buses, the B10-fueled buses emitted smaller amounts of THC, CO, PM, and solid particulate number of PM(2.5), lower oxygenated compounds but higher alkenes; slightly higher NO(x) emissions than China ?a= but slightly lower NO(x) emissions than China V. Consequently, the atmospheric reactivity of VOCs in exhaust gas from the bus fueled with B10 was higher than that from the diesel-powered bus" |
