It is well known that combustion
engine produces about 90% of mechanical energy which is necessary for humanity’s
activity.
The combustion engines operate mainly with a help of oil fuels the sources of
which are rather limited. The oil-importers countries (and Ukraine also)
much worry how to protect combustion engines with a fuel. And because of that
research studies and practices aimed to find effective and alternative fuels are
relevant and very important.
The economy of organic origin
energy carriers, the harshness of harmful substances emission with exhaust
diesel gases, emission dioxide carbohydrate – all these problems make most
countries to research the ways of dangerous engine influence on the environment
decreasing.
The renewable
alternative fuel ”biodiesel” (methyl ethers of vegetable oils-
colza oil, soy oil, sunflower oil and others) has become more
widespread in Europe (1,5
mil/year).
The peculiarity of “bidiesel”, if
to compare with diesel fuel (DT (1)) is its increased in 8-10%
consistence ρ
and twice
increased kinematic viscosity
ν. No
doubts, it influences the injection and carburetion processes in
the diesel cylinder and finally it influences integral
ecological-economic values.
