Volkswagen Group to begin equipping TSI and TFSI engines with gasoline particulate filters from June 2017

Green Car Congress

liter TSI engine in the new VW Tiguan and the Audi A5 in June 2017. Although gasoline direct injection (GDI) enables downsizing with its increased power and lower fuel consumption, it also results in higher particulate emissions. This will reduce particulate emissions from the direct injection gasoline engines by up to 90%.
