Bosch GmbH claims to have developed an exhaust system that reduces diesel emissions to a tenth of the legal limit.
Bosch also allegedly requires no new hardware and works just as well at cold temperatures. If the system works as well as Bosch says it does, automakers may be able to avoid pending bans on diesel vehicles.
“With this new exhaust technology, blanket driving bans in the centers of the world’s major cities will no longer be an issue. Why? Because we now have the technology to resolve the problem of nitrogen oxides in road traffic,” said Volkmar Denner, Bosch’s CEO, at a press conference.
Bosch hasn’t said how much the system will cost to implement. Still, the biggest downside to Bosch’s diesel emissions control system is that it will reportedly only work on new vehicles. Because of that, owners won’t be able to retrofit diesels that are already on the road.
There’s also the question of how trustworthy Bosch is. Many of the components used in Volkswagen’s cheating diesel engines were made by Bosch, and at least one lawsuit has been filed alleging the supplier was a co-conspirator. also reported recently that German regulators may expand their investigation into Bosch’s alleged role in the scandal.
But as Denner told , the company has banned software that recognizes when emissions tests are being conducted, and it no longer allows automakers to modify its products to perform better during testing.
