“…In the 1993 model, Sweden introduced mandatory emission requirements for all heavy-duty vehicles meaning that they will be required to meet the following standards: 1.2 g/kWh, 4.9 g/kWh, 9.0 g/kWh, and 0.4 g/kWh for HC, CO, NOX, and particulates, respectively, when measured according to the 13-mode test method defined by the Stockholm group. The technologies that are being developed to reduce emissions from heavy-duty dieselfueled vehicles include engine modification, improved diesel-fuel, and exhaust-gas after treatment (38). The question of which technology should be used also depends on the air quality objectives.…”

This paper presents results from the characterization of vehicle exhaust that were obtained primarily within the Swedish Urban Air Project, "Tatortsprojektet." Exhaust emissions from both gasoline-and diesel-fueled vehicles have been investigated with respect to regulated pollutants (carbon monoxide [CO], hydrocarbon [HC], nitrogen oxides [NO ], and particulate), unregulated pollutants, and in bioassay tests (Ames test, TCDD receptor affinity tests). Unregulated pollutants present in both the particle-and the semi-volatile phases were characterized. Special interest was focused on the impact of fuel composition on heavy-duty diesel vehicle emissions. It was confirmed that there exists a quantifiable relationship between diesel-fuel variables of the fuel blends, the chemical composition of the emissions, and their biological effects. According to the results from the multivariate analysis, the most important fuel parameters are: polycyclic aromatic hydrocarbons (PAH) content, 90% distillation point, final boiling point, specific heat, aromatic content, density, and sulfur content. -Environ Health Perspect 102(Suppl 4): 13-23 (1994).

“…There are also many studies focused on the effects of lubricating oil on diesel particle emission. From the works done by Cartellieri and Tritthart [17] and Cartellieri et al [18], about 90% SOF and 70% of PM mass in diesel particles were caused by lubricating oil. Taylor [19] studied the effect of lubricating oil volatility on diesel emissions and found that with the removal of light fractions of the lubricating oil below 200 to 260 , the amount of particles decreased.…”

Effect of base oil on the characteristics of emitted particulate matter from a four-cylinder turbocharged diesel engine was investigated. This engine was lubricated with two kinds of base oil (characterized as 150 and 350). The viscosity and flash point of 350 base oil are higher than 150 base oil's. Transmission Electron Microscope, Raman spectroscopy and Thermogravimetric analyzer (TGA) were employed to analyze the particle diameter distribution, nanostructure, graphitization degree and its oxidation characteristics. The primary particles diameter distribution conformed to Gaussian distribution, whereas the mean diameter of 150 base oil was larger than 350 base oil's at 1200 rpm and 2000 rpm. The layer fringe length of 350 base oil was shorter than 150 base oil's, while its separation distance and fringe tortuosity were larger. As to the graphitization degree of 150 base oil, the ratio of the D 1 band to G band areas (A D1 /A G
