"Potentials and Challenges of 1st and 2nd Generation Alternative Fuels for Internal Combustion Engines (ICE)";
Talk: 6th International Colloquium Fuels, Ostfildern (invited); 2007-01-10 - 2007-01-11; in: "Fuels 2007", Technische Akademie Esslingen (ed.); TAE Technische Akademie Esslingen, (2007).

The limited fossil fuel resources as weil as the increasing global demand for energy, accompanied by the reduction of emissions and greenhouse gases, effect the importance of alternative fuels. A promising approach is the usage of special fuels and the adaptation of the engine to the characteristic properties of these fuels. Modified conventional fossil fuels are the first step, followed by synthetic fossil based fuels like GTL (Gas to Liquid). 1st generation bio-fuels gained from food crops, like rape oil, grain, maize, wood etc., are pressing ahead into the market. The usage of these fuels in e.g. Diesel engines demands modifications ofthe engines. Biogenic 2nd generation fuels like BTL accumulate best quality in narrow tolerances. Best engine characteristics and maybe new combustion processes seem to be realistic. The use of these alternatives depends on their availability and their production in accordance with environmentallegislation. Last but not least, the customer's market acceptance has a significant impact on the successful introduction of new fuels.
