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

Green Car Congress

Although gasoline direct injection (GDI) enables downsizing with its increased power and lower fuel consumption, it also results in higher particulate emissions. These are regulated by particle number (PN) in Europe; the limit value for GDI PN emissions will be the same as for light-duty diesel cars in 2017 under Euro 6c. Johnson, T.,
