Emissions from engines that run on fossil fuels are one of the elements that contribute to the decrease in air quality gradually, with the negative consequences that this process implies for the health of the population.

Despite the fact that the most modern vehicles they already include better filtering systems that reduce the expulsion of these particles, the ITV tests are in charge of periodically checking that these systems work correctly. With these tests, it is estimated that vehicle inspections prevent nearly 400 people from dying each year from pollution by detecting which vehicles exceed recommended emissions.

These are the most serious and common defects of a vehicle in the ITV

NOx and other particulate matter from combustion vehicles cause numerous heart and lung diseases. The social cost is valued at 485 million euros and the problem of emissions It is a fault that causes the suspension of the ITV in 14% of the vehicles that attend the stations annually.

The director of the AECA-ITV association Guillermo Magaz insists that these systems need to function properly throughout the life of the vehicle. And that is why the ITV sector has decided to entrust the Carlos III University of Madrid with a study related to the analysis of NOx and PM measurement methodologies applicable to ITVs. The first results of this study were made public in a webinar that took place last September.

The same seminar also offered a vision of the line of work that some European countries are following in this regard. One measure to avoid excess pollution is the new European regulation by which vehicle manufacturers have adapted emission filtering systems to their vehicles, managing to comply with strict emission reductions.
