Measurements within the exhaust plume of a passenger car under real-atmospheric dilution and on-road driving conditions

Löwis of Menar, Sibylle 30 August 2007 (has links) (PDF)
Es wurde ein flexibles Messsystem zur Messung von Anzahlgrößenverteilungen von Partikeln, den Spurengasen NOx und CO2 sowie einiger thermodynamischer Parameter im Abgasstrom eines Diesel-Pkw und eines Benzin-Pkw unter realistischen Fahrbedingungen entwickelt. Das Messsystem besteht aus einem SMPS (Scanning Mobility Particle Sizer) System, einem Multigas-Emissionsanalysator, Thermoelementen, Vaisala-Sensoren, einem Prandtl-Pitot-Rohr und einem Lyman-α-Hygrometer. Es wurde ein spezielles Einlasssystem entwickelt, das variabel im Abgasstrom platziert werden kann. Die Messfahrten wurden zwischen Oktober 2004 und April 2005, sowohl auf der Autobahn als auch im Stadtverkehr, durchgeführt. Die Probenahme erfolgte dabei in einem Abstand von bis zu 95 cm zum Auspuffrohr. Die Ergebnisse werden in der vorliegenden Arbeit dargestellt und diskutiert. Darüber hinaus werden Emissionsfaktoren für die Partikelanzahl individuell für beide Pkws bestimmt und mit Literaturdaten verglichen. Emissionsfaktoren werden zum Beispiel für die Festlegung von Grenzwerten benötigt.
