Not quite a month, Daimler announced the start of the installation of particle filters in their gas engines. From next year the Mercedes S-Class with gasoline engine will begin its installation, before the problem of the increase of emitted particles, a collateral damage of the downsizing more aggressive in gasoline engines. After Daimler, the Volkswagen Group will begin in 2017 the installation of particulate filters on their engines TSI and TFSI, starting with the Volkswagen Tiguan and Audi A5.
The increase of particles emitted by the turbo engines of small displacement is considerable, and has led to the installation of these filters.
These particle filters will be installed in the new Audi A5 and the current Volkswagen Tiguan. The CEO of the Volkswagen Group – Matthias Müller – has presented this strategy of optimization of the internal combustion at its General Shareholders ‘ Meeting, this morning. It is part of the vision of the consortium for the next 10 years, called “TOGETHER – Strategy 2025”. In addition to the installation of these particulate filters will simplify the range of models and versions, which will go from 340 models are about 300 in the short term.
Turning to the particulate filters, according to Matthias Müller will reduce particulate emissions by up to 90% with respect to engines with no filter. For the year 2022 estimated that this technology will have reached up to 7 million group vehicles, equipped with petrol engines turbo charged small displacement and direct injection. Why are the car manufacturers beginning to mount particulate filters on gasoline engines? It is all due to a study conducted by the TÜV-Nord in 2013, with the spotlight focused on the downsizing.
This study showed that the emission of suspended particulate matter – PM2,5 and PM10 – turbo engines of low displacement had been fired. Although emitting less carbon dioxide, in some cases bind up to 1,000 times more particles than the atmospheric peers. This report raised blisters, and as we can see, those blisters are being covered with the same technology that the diesel engines are equipped since a decade ago. An effective technology, but problems and with problems of long-term reliability.
Blockages that give rise to visits to the workshop, deletions illegal of the FAP, etc The scenario is not so negative in the petrol engines, as the higher the temperature of the gases would prevent problems with the regeneration these particulate filters – which in and of itself would receive an amount of particles inferior to that of a turbo modern. Be that as it may, it is more technology, more components, that will result in a slight increase in the vehicles, which will of course be passed on to the customer.
