In parallel with the growing world populations, industries, vehicles,
and equipment these needs lead to a rise in the demand for
energy. It is known that there are a limited amount of fossil-based
fuels as a sustainable energy source. During both the periods of the
production of these fuels and the use of them, the negative impact
on the environment is an important factor and cannot be ignored.
So because of these two factors, researchers are focusing on
renewable and clean energy sources. Considering the current global
economic crisis, the interest in alternative fuels is extremely high.
Separately, one of the goals of researchers is the development of
high efficiency and clean engines.
Alcohol fuels such as methanol, and ethanol etc. have been
appearing as good nominees as alternative fuels for the vehicles
equipped with the SI (spark ignition) engines because they are fluid
and have several physical and combustion properties similar to
