The filters will be used in direct-injection turbocharged engines. Those engines can create more emissions than older, port-injection engines because the newer engines give less time for gasoline to mix with the air in the engine's combustion chamber. The Volkswagen Tiguan SUV's 1.4-liter engine and the Audi A5 2.0-liter engine will be among the first to receive the filters next June. In September, the European Union will start enacting particulate-matter emissions limits that will be one-tenth the current levels.
Volkswagen is making the announcement as it continues to address its diesel-emissions scandal, in which the automaker installed software in its vehicles that let them "cheat" the emissions testing process. VW has sold about a half-million vehicles in the US which contain that software.
And VW may be on the verge of submitting a solution to address that issue with US regulators. Per a recent Bloomberg News report, Volkswagen next week may submit a plan to pay owners of VW's diesel vehicles in the US as much as $7,000 each (and as little as $1,000) for their troubles, in addition to funding a pollution-offset fund. The whole plan may cost VW about $10 billion.
