DUEBENDORF, Switzerland (Reuters) – Engineers working to tackle carcinogenic pollution from cars have developed cheap and simple devices to test the effectiveness of particle filters, which could help take toxic vehicles off roads without resorting to blanket bans.

Municipalities across Europe are struggling to find ways to meet new clean air rules without having to invest billions in electric vehicle infrastructure or banning diesel vehicles altogether.

Regulators - Ways - Emissions - Equipment

Regulators also need to find inexpensive ways to measure real-world emissions without installing costly equipment.

Engineers have now come up with simple, hand-held, battery-powered tools to check within minutes whether cars at low idle speeds have particle filters that work.

Devices - Euros - Police - Garages - Emissions

The devices cost around 8,000 euros ($9,060), making them affordable for police and garages that do emissions inspections.

The new measuring devices will start rolling out in Europe this year for mandatory tests and could help improve diesel engines’ reputation after scandals over carmakers’ use of illegal defeat devices to manipulate exhaust emission tests.

Cities - Diesel - Cars - Nitrogen - Oxide

Some German cities have banned diesel cars, primarily to limit harmful nitrogen oxide (NOx) emissions.

However particulates also kill 5 million people a year globally, Andreas Mayer, director of engineering group VERT’s scientific committee, told Reuters on the sidelines of the group’s annual meeting.

Lot - Stuff - Cars - Particulates - Mayer

“There is a lot of toxic stuff emitted from cars, and the most toxic are particulates,” Mayer said.

The more than 100 million particle filters in use on European roads can, if they work properly, make vehicles’ exhaust less toxic than the ambient air cars burn.

Cars - Cities - Air - Filters - Everything

“These diesel cars, if they are running through cities, are even cleaning the air because the filters are so efficient, so we must do everything...
