报告摘要：
The internal combustion engine has attained a considerable level of sophistication since its invention about 150 years ago and still represents the spark ignited engine worldwide the predominant propulsion in passenger cars today, while the compression ignition engine represents the dominant powertrain in Europe.
Nevertheless there is a high potential for further improvements considering thermal efficiency and engine-out emissions for both engine configurations. The first part of the presentation provides a review of current and future emission regulations for passenger cars. In particular the discrepancy between current statutory emission standards and real driving emissions is highlighted. The second part of the presentation is dedicated to the general requirements for individual mobility and recent strategies for engine efficiency optimization as well as measures to reduce exhaust emissions. In particular the most promising methods to improve fuel consumption are discussed, i.e. optimization of the combustion process, downsizing with boosting, gas exchange strategies, direct fuel injection, etc. All these measures will be discussed in correlation with fuel economy improvement and exhaust emissions reduction for both engine types, the spark ignited (SI - Otto) engine as well as the compression ignition (CI – Diesel) engine. Special issues in SI engines like low-speed pre-ignition (LSPI) as well as the occurrence of exhaust emissions (particulates and nitrogen oxides) in both SI engines and CI engines and the reduction of these emissions by optimization of in-cylinder processes and with exhaust gas after treatment systems will be discussed more in detail.
Finally, the presentation concludes with a detailed review on challenges for future developments, i.e. sustainable fuels for future mobility. Additionally, an evaluation of system efficiency as well as systems costs of the different powertrains for light duty vehicles at real driving conditions and customer demands will be executed. In these comparisons new powertrains like Hybrids and Plug-In Hybrids as well as Battery Electric Vehicles and Fuel Cells will also be considered.
