dc.description.abstractThe Downsizing of internal combustion engines (ICE) is al-ready recognized as a very suitable method for the concurrent enhancement of the indicated fuel conversion efficiency (IFCE) and lowering of the CO2 and NOx emissions [1], [2]. In this report the Ultra-Downsizing is introduced as a still higher development stage of ICE. The Ultra-Downsizing will be implemented here by means of real Atkinson cycles, using asymmetrical crank mechanisms, combined with a very inten-sive multistage high-pressure turbocharging with intensive intercooling. This will allow an increase of ICE performance while keeping the thermal and mechanical strain strength of engine components within the current usual limits.en_US
