For the VW models named in the reports, Bosch supplied the common-rail injection system as well as the delivery and metering module for exhaust-gas treatment.
As is usual in the automotive supply industry, Bosch supplies these components to the automaker’s specifications. How these components are calibrated and integrated into complete vehicle systems is the responsibility of each automaker.
The current issue is not fundamentally about diesel. On the contrary, in combustion-engine engineering, modern diesel technology is the best principle, resulting in the lowest pollutant emissions. Modern diesel powertrains are indispensable for achieving European greenhouse-gas emissions targets. The diesel means protection for both the environment and the consumer.
Bosch develops injection and exhaust-gas treatment systems that can reduce emissions in every driving situation and operating mode – also at high speeds and when accelerating hard. Diesel remains a key technology for achieving global CO2 targets. Most importantly, Bosch believes that there is potential to further reduce the CO2 emissions from diesel engines by as much as 10 percent.
There is also significant potential for further reducing nitrogen-oxide emissions from diesel vehicles. For example, Bosch’s Denoxtronic allows a reduction of up to 95 percent, also in conditions not covered by the official driving cycle tests. Bosch remains committed to the diesel.
