Germany just can’t seem to give up on the diesel engine. Only last month, Volkswagen – which gave the world Dieselgate – said it was expecting something of a diesel renaissance. Now engineering giant Robert Bosch reckons it has come up with a exhaust system that sharply cuts emissions and may just help keep the technology on the road.
The latest innovation involves better management of exhaust temperatures so that NOx emissions can be cut to around one-tenth of the legal limit.
Bosch CEO Volkmar Denner says bullishly that the new tech would obviate the need for diesel driving bans in large cities. “There’s a future for diesel,” he says. “We want to put a stop, once and for all, to the debate about the demise of diesel technology.”
The company needs to work fast to convince the authorities. Hamburg is set to become the first German city to introduce a diesel ban. The move follows a federal court’s recent ruling that metros could introduce their own independent restrictions on urban traffic.
