摘 要：In this paper, on-board Measurements of particle emissions were carried out on a VW diesel car in Shanghai real roads.The test fuels included pure petroleum diesel (D100) and three different alternative fuel blends, 10％ biodiesel blend (BD10), 10％ coal-to-liquid fuel blend (C10) and 10％ gas-to-liquid fuel blend (G10) in volumetric mixture ratio.Results showed that particle emissions in freeways were terrible, and particle number emission ratios from urban roads were high.The test alternative blend fuels of BD10, Bul0, G10 and C10 all have positive effects on the particle emissions of test diesel car.
