    Bosch Says It's Made a Breakthrough That Can Save Diesel Engines

    Pipework sits on the tubocharged direct injection diesel engine (TDI) of a Volkswagen AG (VW) Passat automobile in London, U.K., on Wednesday, Dec. 2, 2015. Volkswagen is grappling with an emissions scandal on three fronts: cheating software installed in about 11 million vehicles worldwide with 1.2-, 1.6- and 2.0-liter engines; irregular carbon dioxide ratings on about 800,000 vehicles in Europe; and questionable emissions software in about 85,000 VW, Audi and Porsche vehicles with 3.0-liter diesel engines in the U.S. Photographer: Miles Willis

    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," Bosch Chief Executive Officer Volkmar Denner said Wednesday at a press conference outside Stuttgart.

    The German engineering giant, the biggest supplier of diesel-engine technology to global automakers from Volkswagen AG to General Motors Co. to Fiat Chrysler NV, is stepping up the fight against eroding market share sparked by VW’s 2015 emissions-cheating scandal. While tens of thousands of jobs hinge on the technology, customers are increasingly opting for gasoline engines as cities like Paris and London consider imposing driving bans to improve air quality.
    Automakers have relied on diesel to help the industry meet limits on CO2 emissions, a contributor to global warming. But while it emits less CO2 than gasoline-fueled engines, the technology also generates nitrogen oxides that help create harmful smog, a problem most acute in big cities.

    Bosch’s new process optimizes thermal management of exhaust temperatures, slashing nitrogen oxide emissions to one-tenth of the legally permitted limit, and doesn’t require new hardware, Denner said. The system keeps emissions stable even at cold temperatures, he said.
    “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," Denner said.

    Bosch’s role as leading global supplier has come under scrutiny as German prosecutors investigate potentially illegal diesel-engine technology used by automakers to pass emission tests. Denner reiterated Bosch fully cooperates with the relevant authorities. He called for more transparency in emission tests for cars with combustion engines as well as electric vehicles to allow a realistic view of the exact impact on the environment and air quality.
    He said the company is prohibiting technology that recognizes test cycles and its products aren’t allowed to be optimized for test situations any more. Regulators have stepped up efforts to narrow the gap between official emission labels based on lab tests and real driving emissions.

    Would you care to paraphrase the article, or provide a direct link to it?
    Bloomberg's crazy quilt of a frontpage has changed since, well, probably, ten minutes ago.

    I found it yesterday just by scrolling down the Tech page. Can't see hide nor hair of it today though,
    Mike. Will broaden my search.
