COMPOSITION AND SIZE OF DIESEL PARTICULATE EMISSIONS FROM A COMMERCIAL EUROPEAN ENGINE TESTED WITH PRESENT AND FUTURE FUELS

This paper reports the results of experimental research on particulate emissions from a typical indirect injection diesel engine running under five different operating conditions and tested with fourteen types of conventional and alternative fuels. The chemical analysis of the emitted particulate matter showed, for example, that the total mass of particulate emission decreases when using biofuels owing to a reduction in their insoluble fraction. Composite analysis made it possible to identify the hydrocarbons adsorbed on the soot surface, to quantify their proportion with respect to the total particulate mass and to distinguish between their origins. The results of surface analysis using scanning electron microscopy showed that the number of particles detected per filter surface increased with load for all fuels. This analysis also showed the effect of some fuel specifications (aromatic and sulphur content) on certain parameters related to the particle size distribution obtained from the filter images. The number of particles dramatically decreases with the concentration of biofuels.
