Robert Bosch GmbH said its engineers have developed a new diesel-exhaust system that cuts emissions far below legal limits taking effect in 2020 and can help automakers avoid potential driving bans in Europe that threaten to doom the engine technology.

“This breakthrough offers the opportunity to shift the heated debate over diesel into new territory and, hopefully, bring it to a close," Chief Executive Officer Volkmar Denner said Wednesday at a press conference outside Stuttgart.
