For achieving the forthcoming CO2 emission targets of 95g/km by 2020 and for the years beyond, comprehensive activities for powertrain technology as well as development methodology has to be utilized. It will by far not be enough to add a few single technology features to achieve the desired result. More and more the success will result from comprehensive combining of synergetic utilization of complementary effects. This will be the powertrain perfectly matched to the vehicle, including the energy source, and all together integrated by means of advanced development tools and methodology.
The content of this paper will address the following topics:
- Global and regional trends and market penetration of propulsion technologies
- Combustion system: Outline of highly efficient SI engines, featuring advanced charging systems, utilization of Miller cycle and high rates of cooled EGR
- Tools and methodology for highly efficient development processes (highly accurate fuel consumption measurement, particulate number, optical instrumentation, transparent engine, calibration tools)
