Partikelminderung bei Ottomotoren durch Filtersysteme

Verbrennungsmotoren produzieren umweltschädliche Abgase, weil der Treibstoff – ein Gemisch aus Kohlenwasserstoffen – nur unvollständig verbrennt. Damit die Schadstoffe nicht in die Luft gelangen, sind Benzin- und Dieselfahrzeuge mit Katalysatoren und teilweise zusätzlich mit Partikelfiltersystemen ausgestattet. Sie reinigen den Abgasstrom, bevor er den Auspuff verlässt.
