Sustainable mobility through innovation

è  through variable valve control, scavenging for gasoline engines, and Denoxtronic for diesel engines

è  through direct injection coupled with turbocharging and engine downsizing

The internal-combustion engine will dominate until electrical powertrains establish themselves in larger numbers. Bosch has the technology to reduce the fuel consumed and the CO2 emitted by internal-combustion engines by another 30 percent by 2020:

–

è  through start-stop systems, optimized thermal management, brake energy recuperation, and on-demand management of electrical auxiliary systems

Diesel Systems

è Diesel cars are economical •  More than 30 % lower fuel consumption than port fuel injection gasoline engines on average •  Longer engine lifetime •  Higher resale value than gasoline cars

è Diesel cars are clean •  About 80 % reduction in harmful emissions over the last 10 years •  About 25 % lower CO2 emissions compared to port-fuel injection gasoline engines •  Quiet operation due to innovative pre-injection

è Diesel cars are fun to drive •  High specific power output •  High torque à up to 50 % higher torque than gasoline cars •  Better acceleration at lower engine speeds •  Less fuel stops due to higher mileage

Particulates Reduction by Clean Diesel

The Clean Diesel has almost no further particulate emissions

Clean

è  The Clean Diesel has 98%* less particulates than the diesel engines of 1990. The particulates generated in the engine are filtered out by the particulate filter.

* Comparison between ECE83 and Euro 5 emission legislation.
