Ultra-Downsizing of Internal Combustion Engines

Autor: Victor Gheorghiu

Publikováno v: Sustainable Automotive Technologies 2012 ISBN: 9783642241444

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 [1], [2]. In this report, ultr

CO2-EMISSION REDUCTION BY MEANS OF ENHANCING THE THERMAL CONVERSION EFFICIENCY OF ICE CYCLES

Autor: Victor Gheorghiu

Publikováno v: SAE Technical Paper Series.

Most automobile manufacturers have developed hybrid vehicles that combine an internal combustion engine and an electric motor, fusing the advantages of these two power sources. For example, Toyota, in its Prius II, uses a highly efficient gasoline en

Enhancement Potential of the Thermal Conversion Efficiency of Ice Cycles by Using of a Real Atkinson Cycle Implementation and (Very) High Pressure Turbo Charging

Autor: Victor Gheorghiu

Publikováno v: ASME 2010 10th Biennial Conference on Engineering Systems Design and Analysis, Volume 3.

Most recent implementations of the Atkinson cycle are not optimal from the point of view of Thermal Conversion Efficiency (TCE). For example, Toyota has put in its Prius II a gasoline engine which should achieve high efficiency by using a modified At
