Description: Das Projekt "Einfluss der Kraftstoffzusammensetzung auf die Partikelbildung im Dieselmotor" wird vom Umweltbundesamt gefördert und von Technische Hochschule Aachen, Lehrstuhl für Angewandte Thermodynamik und Institut für Thermodynamik durchgeführt. This project brings together two major-oil-companies, one of Europe's largest vehicle manufacturers, a research institute and four academic laboratories in an innovative and tightly focussed programme to investigate the effects of fuel density and composition on diesel soot and particulate emissions. The interplay between refinery costs, fuel economy, and environmental legislation makes this one of the most important topics in future road transport strategy. The engine and fuel aspects of overall diesel performance, including the formation of pollutants, interact strongly but are generally studied separately. As a result, the interactions are poorly understood and the limited data available are not consistent. The participants in this group combine expertise on commercial diesel fuels, leading edge technology in production engine design, and the range of research skills to bring new insights to the problem and transfer those insights for industrial implementation. The technical objectives are to establish the effect of fuel composition on the production of polyaromatic hydrocarbons (PAH) and soot emissions from diesel engines by a carefully planned, progressive, programme of measurements and chemical modelling. Investigations of a soot suppressing additive are included. The experimental work comprises basic flame measurements, in cylinder engine sampling and tail-pipe emissions studies in a single-cylinder research engine and both passengercar and truck engines. The results will be used to validate and test an existing chemical modelling code and extend its application to engine performance. These closely-linked theoretical and modelling studies will improve the understanding of the physical and chemical phenomena involved in pollutant production, particularly the formation of soot. The programme will establish how far fuel based approaches can contribute to future EC directives on diesel emissions without the need for exhaust clean-up. It will also provide valuable technical data for the discussion on standards for European diesel fuel, related repercussions on refinery economics and fuel availability.
