The thesis explains the economic and political motivation of China's drive towards Africa, the political framework for this and the approach to the African continent via trade, investment and aid. The Sino-African cooperation is exemplified by the countries Angola, Sudan, Zimbabwe, Nigeria, Kenya and South Africa. Finally several points of criticism and the perceptions of the Western world towards China's engagement with Africa will be examined.
In the present work of thesis, exhaust gas temperature transients of different diesel electric hybrid configurations equipped to a mid-size European passenger car were evaluated through numerical simulation. Different degrees of hybridization, from micro to mild hybrids, based on General Motors BAS powertrain architecture, enabling different hybridization strategies, were taken into account in order to obtain a preliminary assessment of the impact of micro and mild hybridization on the exhaust aftertreatment system's efficiency over the regulated New European Driving Cycle. Thereto, the simulation software GT-SUITE featuring an one dimensional code was used to build a model of the reference vehicle with conventional powertrain, to which the corresponding BAS configurations were later equipped. The simulated exhaust gas temperature transients were then compared and evaluated.
