Abstract
The downsizing of internal combustion engines (ICE) is already
recognized as a very suitable method for the concurrent enhancement
of indicated fuel conversion efficiency (IFCE) and the lowering of
CO₂ and NOx emissions.
In this report, ultra-downsizing is introduced as an even higher
stage of development of ICE. Ultra-downsizing will be implemented
here by means of real Atkinson cycles using asymmetrical crank
mechanisms, combined with multi-stage high-pressure turbocharging
and very 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.
