The future of gasoline engines
Both the future test cycles and more fuel-efficient transmission and electrification concepts are shifting the ICE operation towards higher engine loads. Whereas in the past, FE measures with Gasoline Engines were mainly concentrated on the reduction of throttle losses, in future the extension of the sweet spot area becomes decisive. Consequently, a complete re-evaluation of existing technologies as well as new technology approaches are required also in view of the simultaneously aggravated limits for pollutant emissions. Highly differentiated market demands will result in an increasing differentiation of specific power between “Top Performance / Image Concepts” heading up to 200 kW /l and “Fuel Economy Concepts” targeting a minimum BSFC of 200 g/kWh. In spite quite different boundaries, various base elements like knock resistant combustion systems, highly efficient charging devices, optimized friction, etc. can be utilized both for highest power and for best efficiency.
