dc.description.abstract | Road transport is still an essential part of the transport around Europe and has tremendous importance for all EU citizens. Unfortunately, also is one of the major contributors to air pollution and climate change. Much research into methods of reducing gas emissions is being carried out because of concern over high levels of pollutants in vehicular exhaust gas, and associated government regulations specifying limits on them. Research has been directed into novel engine configuration, thermal and catalytic reactors for oxidation of pollutants, as well as alternative fuel systems. The aim of this project titled “Investigation of Knock limits of Dual Fuel engines” was the evolving of a system to utilize alcohol as alternative fuel in a dual fuel engine. For this purpose a dual fuels diesel engine was developed. A short review about this kind of engine and the engine knocking concept, the required modifications, the evolved system and the experimental results are presented in this article. Exhaust gases are investigated, where compared with the conventional diesel engine HC, NOx, CO and CO2 emissions were decreased. Nevertheless, not only methanol was used as primary fuel in the dual fuel engine, in order to compare the use of more fuels gasoline was also used in the same dual fuel engine giving worse results than this kind of alcohol. Furthermore, an investigation about the knock limits on this kind of engines was done, where the experiments showed that alcohols, methanol in this case, had a better resistance to this not wanted combustion phenomenon, which make shorter the engine durability, than gasoline. |
