Complex Analysis of Power Output and Emission Parameters of High-Power Motorcycles at Application of Advanced and Sustainable Fuels and Their Mixtures.

The presented scientific study is focused on a complex analysis of power output and emission parameters concerning an experimental motorcycle. In spite of the fact that there are at disposal considerable theoretical and experimental results, which include also matters of the L-category vehicles, there is, in general, a lack of data covering the experimental tests and power output characteristics of racing, high-power engines that represent a technological peak in the given segment. This situation is caused by an aversion of motorcycle producers to publicize their newest information, especially in the case of the latest high-tech applications. The given study is focused on all the main results obtained from the operational tests performed on the motorcycle engine in two testing cases: first with the original arrangement of the installed piston combustion engine series produced and second with the modified engine configuration proposed in order to increase the combustion process efficiency. Three kinds of engine fuel were tested and mutually compared within the performed research work: the first was the experimental top fuel used in the world motorcycle competition 4SGP, the second was the sustainable experimental fuel, the so-called superethanol e85 developed for maximum power output and minimum emission, and the third was the standard fuel, which is commonly available at gas stations. Applicable fuel mixtures were also created with the aim to analyze their power output and emission parameters. Finally, these fuel mixtures were compared with the top technological products available in the given area.
