Abstract

Bei einem Verfahren zur Messung der Partikelemission von Verbrennungsmotoren, insbesondere im realen Fahrbetrieb, wird eine Verdünnung eines Abgas-Teilstroms mit gefilterter Umgebungsluft vorgenommen.Um dabei trotz Vereinfachung des Verfahrens eine erhöhte Genauigkeit zu erzielen, werden der Massenfluss des Abgas-Teilstromes ebenso wie der Verdünnungsluftstrom annähernd konstant gehalten, wird der verdünnte Abgas-Teilstrom sowohl einer gravimetrischen Messung als auch einer kontinuierlichen Messung einer charakteristischen Partikeleigenschaft unterzogen, wird das Signal der charakteristischen Partikeleigenschaft mit dem Filterstrom multipliziert, über die gesamte Messdauer der gravimetrischen Messung integriert wird und daraus ein Skalierungsfaktor zwischen der gravimetrisch gemessenen Partikelmasse und der aus der integrierten Partikeleigenschaft bestimmten Partikelmasse bestimmt, und wird die Partikelemission während eines Messintervalls aus der über das entsprechende Messintervall geeignet gewichteten, integrierten und mit dem Skalierungsfaktor multiplizierten kontinuierlichen Messung berechnet wird.Anstelle konstanter Abgas- bzw. Luftströme kann mit veränderlichen Strömen gearbeitet werden, solange der Massenfluss des Abgas-Teilstromes, der Verdünnungsluftstrom sowie die Zeitverschiebung zur kontinuierlichen Messung zeitlich genau bestimmt werden.In a method for measuring the particle emission of internal combustion engines, in particular in real driving, a dilution of a partial flow of exhaust gas is carried out with filtered ambient air. In order to achieve increased accuracy despite simplification of the method, the mass flow of the exhaust gas partial flow as well as the dilution air flow If the diluted partial exhaust gas stream is subjected to both a gravimetric measurement and a continuous measurement of a characteristic particle property, the signal of the characteristic particle property is multiplied by the filter stream, integrated over the entire measurement period of the gravimetric measurement, and a scaling factor between them determined gravimetrically measured particle mass and determined from the integrated particle property particle mass, and the particle emission during a measuring interval from the on the corresponding Messint Instead of constant exhaust or air streams can be used with variable currents, as long as the mass flow of the exhaust gas partial flow, the dilution air flow and the time shift for continuous measurement are determined accurately in time.
