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. |
