Engine Technology International is reporting that following recent announcements, Bosch details its new diesel emissions technology. These developments could enable vehicle manufacturers to reduce nitrogen oxides (NOx) emissions to levels that will already comply with future limits.
Even in RDE (real driving emissions) testing, emissions from vehicles equipped with the new Bosch diesel technology are not only significantly below current limits but also those scheduled to come into force from 2020.
According to Bosch, factors that have hindered the reduction of NOx emissions in diesel vehicles, include driving style. The technological solution developed by Bosch is a highly responsive air-flow management system for the engine. A dynamic driving style demands an equally dynamic recirculation of exhaust gases. This can be achieved with the use of a RDE-optimised turbocharger that reacts more quickly than conventional turbochargers.
