Research Measuring Techniques

The relevance of a reliable and accurate determination of the particle number in engine exhaust steadily increases due to the expansion of particle number limits from light-duty diesel- over heavy-duty diesel- through to light-duty gasoline-diesel engines, but also as a reference for a future mobile determination of the particle number. At the Institute for Internal Combustion Engines of the Technische Universität München, a comparison of four parallel-operated partial flow dilution- and particle counting systems for particle number determination on a heavy-duty engine was conducted as part of a FVV project.

1 Regulation of the Particle Number

Due to potentially negative health effects of nanoparticles, which in particular are also produced in internal combustion engines, their control and reduction is of great importance. As a further development of the previously valid regulations for particle emissions control in Europe, which based on the particle mass limit (PM filter...



The scientific results were created on behalf of the German Research Association for Internal Combustion Engines e. V. (FVV) within the framework of the research project PN measurement procedures (1073). The projects experimental part on engine exhaust was performed at the Institute for Internal Combustion Engines (Lehrstuhl für Verbrennungskraftmaschinen, LVK) at the Technische Universität München. Within this project parallel work with emphasis on aerosol metrological issues was carried out by the model aerosol laboratory at the Institute of Hydrochemistry and Chemical Balneology (IWC, Prof. Dr. Reinhard Niessner). The work was funded by equity capital of the FVV. The scientific work was supported by a project steering committee, headed by Dr. Harald Beck, MAN Truck & Bus AG. Special Acknowledgments go to the companies involved in the loan of the used test facilities: Airmodus, AVL, Control Sistem, MS4, Horiba, MAN Truck & Bus, Maha, Nova Systems and Pegasor.
