Starting June 2017, Volkswagen Group will be installing particulate filters for their gasoline-powered engines with the 1.4-liter Turbocharged Stratified Injection (TSI) in the new Volkswagen Tiguan and 2.0 Turbocharged Fuel Stratified Injection (TFSI) in the Audi A5. With this, emissions of fine soot particles from the two engines will be reduced up to 90 percent.
Dr. Ulrich Eichhorn, Head of Group Research and Development, stated that particulate filters for diesel engines are already proven and tested. Installing them on gasoline engines will allow them to follow stricter emissions.
“Following increases in efficiency and lower carbon dioxide output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard,” said Eichorn.
Beyond that, Dr. Eichhorn also added that all models will be equipped with the latest and most effiicient silicon controlled rectifier (SCR) which is a key component in catalytic converter technology.
In review, the all-new Volkswagen Tiguan first debuted during the 2015 Frankfurt Auto Show. Depending on the model, the 1.4-liter engines are available in two power outputs; 125 PS and 150 PS. On the other hand, the 2016 Audi A5 was revealed last June and has two TFSI engines that have an output rating that ranges from 190 PS and 286 PS.
