The Automotive Drive of the Future
BOXBERG, GERMANY - What will the vehicle drive of the future look like in five, 10 and 20 years' time? " For over 100 years, consideration of that question has sparked Bosch's ability to be a major force in the development of the automobile" says Dr. Rolf Leonhard, executive vice president for Engineering, Diesel Systems, Robert Bosch GmbH. He identifies lower emissions, alternative drives and renewable fuels as the three key elements of the road map to the vehicle of the future that Bosch will focus on over the next two decades.
Pollution-free mobilityLeonhard says that Bosch is working on automotive evolution in four different ways. Engineers are unlocking the potential of the internal combustion engine - potential that is still far from exhausted. This applies equally to both diesel and gasoline engines.
Consequently, the energy efficiency of diesel makes it a more environmentally friendly vehicle drive system, he says: "That is why Bosch will do everything it can to help diesel break through in North America and Asia as well, following its success in Europe."
Bosch engineers already have their sights firmly fixed on these more stringent emissions targets, Leonhard notes, and they will provide the right technical solution at the right time, even for challenging values such as these.
"We will meet these targets by developing specific technologies in the internal workings of the engine, such as technology that allows higher charge-air pressure in the exhaust-gas turbocharger with higher exhaust gas recirculation rates at part load, that further optimize the combustion process," he says.
While the automobile industry now has diesel particulates under control, tackling concerns regarding even stricter nitrogen oxide emissions, in both North America and Europe, remains the challenge. On the one hand, says Leonhard, optimized injection technology is enabling Bosch to reduce the engine's "raw emissions" - that is, before post-treatment in the exhaust gas flow. On the other hand, the additional diesel particulate filter is cutting soot emissions to such an extent that even-stricter emission limits will be attainable in the future.
"As of 2009, Bosch's product portfolio will boast a new generation of diesel particulate filters," Leonhard says, "making it the one-stop supplier for diesel technology and corresponding exhaust gas treatment systems - both optimally attuned to one other."
