Summary

The limitations of the availability of fossil energy carriers as well as the commitment to reduce CO2 emissions resulting from the Kyoto agreement will increase the necessity of
providing vehicle propulsion systems with significantly increased efficiency in comparison to the current state. The best efficiencies of todays piston-type engines only reach a range between 38 – 41%. The reasons mainly can be found in a compromised adaptation of the thermodynamic process to the mechanic boundaries of the piston-type engine which
remained principally unchanged for the recent 100 years and which are characterized by heat supply into the cool gas already before and during the compression, heat losses of the compressed gas before and during the expansion, mechanical restrictions during the expansion and only insufficient usage of exhaust gas enthalpy.
