Das Kaltstart-Dilemma

Katalysatoren vorwärmen

(PresseBox) (Dübendorf, )
Bei Hybridautos und Plug-in-Hybriden kommt es häufiger zu Kaltstarts als bei normalen Verbrennungsmotoren, nämlich immer dann, wenn der Verbrennungsmotor ausgeht und der Elektromotor das Auto durch die Stadt schiebt. Wie schnell lässt sich der Katalysator vorwärmen, damit er Abgase dennoch gut reinigen kann? Was wäre die Methode der Wahl? Ein Forscherteam der Empa hat es ausgerechnet.

Von Januar bis September 2019 wurden knapp 17 000 Hybride und Plug-in-Hybride in der Schweiz eingelöst – eine Zunahme um 60 Prozent im Vergleich zum Vorjahr. Tendenz stark steigend. Diese Autos können einige Kilometer weit rein elektrisch durch die Stadt fahren.
