Since 2018, only SCR exhaust gas treatment systems have been used in Volkswagen models with diesel engines. SCR (selective catalytic reduction) technology significantly reduces nitrogen oxides in the exhaust gas. Volkswagen has now developed the next evolutionary stage of the SCR system which is called twin dosing.
Dieselgate scandal attracts some major changes for Volkswagen future strategies. The German group announced it will switch over to installing only diesel drives with SCR and AdBlue technology in Europe and North America as soon as possible. According to most recent press release, â€diesel vehicles will only be equipped with exhaust emissions systems that use the best environmental technology.â€
