The various brands of the Volkswagen Group will begin in 2017 to implement particle filters in their gasoline engines with direct injection and supercharged, known as TSI and TFSI, depending on the brand. This reduce up to 90% of the particulate pollutants, which will help meet the regulations in the future emissions.
The Volkswagen Tiguan with petrol engine will be the first models to receive particulate filters
The reason why the Volkswagen Group has decided to adopt this solution is that the engines with gasoline direct injection generate higher temperatures in the combustion chambers, which gives rise to a greater number of particles pollutants in the exhaust gases. This type of solutions are not needed in petrol engines with indirect injection multipoint, each time more scarce and the Volkswagen Group relegated to some of its smaller engines.
The regulations Euro 6c will be that from September 2017 then that petrol cars have to reduce emissions of particles. The first models of the German group in receiving these particulate filters for gasoline engines will be the Volkswagen Tiguan 1.4 TSI and Audi A5 2.0 TFSI. Face to 2022, it is expected that each year 7 million vehicles gasoline VAG Group make use of these devices the anti-pollution.
