Requirements for future gasoline engines

Abstract

The worldwide CO2 and fuel economy legislations will converge on extremely low level requiring fleet-CO2 reductions of up to 45% by 2025. This not only enhances electrification and alternative fuels, but also demands break through innovations with the conventional powertrain. On top, more stringent requirements regarding the " con-ventional " pollutants, Particulate Number and especially the future Real Driving Emission legislation will have a major impact both on powertrain technology but also on powertrain development, validation and in field compliance. One of the key aspects is a comprehensive system development not only focused on the engine, but incorporating the whole powertrain, vehicle aspects and the huge vari-ety of customer operating conditions to a much larger extend than in the past. To mas-ter these enhanced demands within short time to market, new development tools and methodologies will be applied.
