particle filters, which up to now were employed in the diesel, perhaps they are one of the components that are most hated by drivers, but at the same time more important to mitigate the harmful effects that our daily activity triggers in the air of our cities. They are a component that has not been without problems, and through which the air of our cities has been freed of particles that are associated with serious health problems. After the diesel, as we go forward, that the new generation of petrol engines will also begin to equip particle filters. The Volkswagen Group because we anticipated that their first models in the equip it will be an Audi A5 and Volkswagen Tiguan, but we can already disclose that from 2017, and in different stages, all engines gasoline direct injection of the Volkswagen Group, all TSI and TFSI, will incorporate this technology. Absolutely everyone.
why Volkswagen will incorporate the filters of particles in your petrol engines? And why now?
Volkswagen will not be the only manufacturer to adopt this technology. Mercedes-Benz has already announced it own, and it’s a matter of time that other manufacturers go by climbing onto the cart. Although the measure is announced, often, under a background, environmental, and concern for emissions of polluting gases and particles – in this case – as a result of the combustion, the only thing certain is that the tightening of the emission regulations of the European Union requires the use of this technology to comply with the objectives and proposed limits.
A legal requirement and not a mere environmental concern
particulate matter emissions from gasoline engines will be one of the most watched with the entry into force of the new iteration of the Euro VI (Euro 6c) planned for the coming year. Not to mention the extensive monitoring that is intended to be made of the emissions, not only from the bank of rollers, but also from environments of “real world” (or, better said, realistic) in line with the driving everyday that will make drivers in real life, outside the laboratory.
Of time, Volkswagen will start with this process in 2017, starting with the already mentioned Audi A5 (in the four-cylinder engine 2.0 TFSI) and Volkswagen Tiguan (in the engine 1.4 TSI). The following engines incorporating this technology in all the brands of the Volkswagen Group, will be progressively introduced.
The pros and cons of particle filters
According to Volkswagen, the particle filter, an inexpensive and effective solution to reduce particulate emissions from these engines, is able to reduce the emissions of particulate matter (PM10 and PM2,5) in a 90%. There are studies in which it has been shown that, in turbocharged engines of gasoline and small displacement, is emitted up to 1,000 times more particles than in the respective naturally aspirated engines used until the arrival of the turbo. If you want to know the health consequences of these particles (PM10 have a diameter less than 10 µm and PM2,5 to 2.5 µm) is enough to read any of the documents of air quality, as the guides published by the WHO (page 9). I assure you that just a little bit of information to take awareness of how important these systems are, for the problematic that has been for a lot of drivers (and that does not mean to demand that manufacturers develop systems that generate less inconvenience to the driver).
particulate filters have been associated, historically, and with reason, to the numerous problems that have brought headache to many drivers of diesel. That was the reason that led us to prepare an article with 5 tips in order to avoid damage of the particulate filter of the diesel, and why many drivers came even to perform a modification illegal, and very harmful to the public health, to cancel the particulate filter. Some drivers and workshops have been sanctioned for this same reason, and earlier this year it was announced that the ITV endurecerían controls to detect these irregularities.
a time to this part, the manufacturers have significantly improved their filtering systems of particles and, above all, their capacity to avoid the saturation of the filter and, ultimately, failure.
that being Said, and as a conclusion, we understand that the desire of many manufacturers by introduce the particle filters in their gasoline engines responds, solely and exclusively, to the tightening of the emission regulations. In any case, yes it is positive that many will already be ahead of the picture that we find in the next few years. And, on the other hand, we also welcome the fact that these systems are applied, and to extend to new engines, including those that may not have been extreme in the control, such as engines, gasoline direct injection and turbo.
