Abstract
The Gasoline engine will represent a significant portion of the future powertrains beyond 2020. Further development of low friction engines, new combustion processes, alternative fuels and electrification are technologies that contribute to achieve the future CO2 emission targets in the automotive and transportation sector. Besides series production readiness the essential aspect for the application of these different technologies is an attractive cost/benefit-ratio.
Friction reduction as a cost effective measure contributes to achieve a further reduction in fuel consumption of internal combustion engines. New development processes and simulation tools in combination with advanced measurement techniques are used to stretch the limits for future powertrains. Furthermore, beside the optimization of combustion efficiency e.g. by further increase of variability in engine functions like valve train or compression ratio, the use of alternative fuels can play an important role.
In this contribution it will be shown how the Gasoline engine can achieve the CO2 emission target of 2020 and beyond. A combination of thermodynamic and mechanical measures will be discussed.
