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

“There’s a future for diesel. Today, we want to put a stop, once and for all, to the debate about the demise of diesel technology.” It was with these words that the Bosch CEO Dr. Volkmar Denner, speaking at the company’s annual press conference, announced a decisive breakthrough in diesel technology. A breakthrough in the management of diesel emissions, enabling diesel cars to undercut future limits for nitrogen oxide (NOx) by almost 90 per cent.

Cars must currently emit no more than 168mg/km (milligrams per kilometre) of NOx and, in 2020, that limit will reduce to 120mg/km in real-world driving tests, and 80mg/km in lab assessments. But new technology developed by Bosch allows a diesel VW Golf to emit just 13mg/km of NOx in mixed driving conditions, measured using the latest RDE paradigms.

Announcing the breakthrough at the company’s annual press conference, Bosch’s chief executive, Dr Volkmar Denner, said: “There’s a future for diesel. Today, we want to put a stop, once and for all, to the debate about the demise of diesel technology.” Denner said the company was “pushing the boundaries of what is technically feasible.”

Even in urban driving, where emissions are typically far higher than on the open road, cars equipped with the new technology emit around 40mg/km of NOX - roughly a third of the permitted limits being introduced in 2020. This means, Denner said, that “diesel will remain an option in urban traffic, whether drivers are tradespeople or commuters.”

The technology works by managing exhaust gas recirculation and using a combination of advanced fuel-injection technology, a newly developed air management system, and intelligent temperature management. It is effective as soon as a car is started and works at all engine speeds, allowing it to operate effectively whether the vehicle is driven dynamically or slowly, in freezing conditions or in summer temperatures, on the freeway or in congested city traffic. The system is also effective when drivers accelerate quickly.



Journalists were given the opportunity to drive around Stuttgart in cars equipped with the new system. The results captured from these demonstration drives showed average NOx emissions of under 40mg/km, despite the cars being driven in city centre traffic.

While the system cannot be easily retrofitted to old cars, it is based on already-existing components and is available immediately. It can be incorporated into car makers’ production projects, and the system allows diesel engines to maintain their fuel economy and carbon dioxide (CO2) emissions.



Denner promised more improvements in emissions management would be forthcoming, as Bosch plans to use artificial intelligence to build on its emissions reduction technology. “We firmly believe that the diesel engine will continue to play an important role in the options for future mobility,” he added.

Denner said electric cars had a fundamental role to play in future transport, but “until electromobility breaks through to the mass market, we will still need these highly efficient combustion engines.”
