Benzinmotoren mit Direkteinspritzung sind gefaehrlicher fuer Umwelt und Gesundheit als bislang angenommen. Das beweisen die Ergebnisse eines neuen Tests, den die Deutsche Umwelthilfe e.V. (DUH) bei der Abgaspruefstelle der Fachhochschule Bern (AFHB) in Auftrag gegeben hat. Die erstmals auch unter realen Fahrbedingungen gewonnenen Daten machen deutlich, dass der Ausstoss von Nanopartikeln und anderen Schadstoffen, im Vergleich zu den Ergebnissen auf dem Rollenpruefstand, auf der Strasse massiv ansteigt. Deutlich hoehere Emissionen gibt es jedoch auch im Labor, sobald die Testbedingungen einem realistischeren Fahrverhalten angepasst werden. Aus diesem Grund fordert die DUH eine rasche und umfassende Markteinfuehrung entsprechender Abgasreinigungstechnologie, wie sie bei Dieselmotoren seit langer Zeit im Einsatz ist. Die Abgaspruefstelle der Fachhochschule Bern hatte die Emissionen eines Hyundai 30 GDI (1.6 L) und eines VW Golf VII TSI 1.4 L in verschiedenen Messzyklen sowie in jeweils fuenf gleichen Strassenfahrten pro Fahrzeug ermittelt. Zur Messung von Nanopartikeln verwendete die AFHB ein ?on board-Geraet (NanoMet 3). Anschliessend vermass die Abgaspruefstelle beide Autos auf dem Pruefstand nach dem Neuen Europaeischen Fahrzyklus (NEFZ) und dem sogenannten Autobahnzyklus, der im Vergleich zum NEFZ einen realitatnaeheren Fahrbetrieb simuliert. Den Autobahnzyklus fuehrte sie beim Golf einmal ohne und einmal mit eingebautem Partikelfilter durch. Waehrend der VW Golf im NEFZ-Zyklus sowohl die ab 2014 als auch ab 2017 geltenden Grenzwerte fuer Partikelanzahl einhielt, blieb der Hyundai nur unter den schwaecheren Grenzwerten fuer 2014. Auf der Strasse zeigte sich dagegen ein gaenzlich anderes Bild: Die Emissionen des Golf stiegen stark an und waren hoeher als die des Hyundai. Der im Golf fuer einen zweiten Durchlauf eingebaute Partikelfilter verringerte den Ausstoss fast vollstaendig.
