Engine

driven power plants, run by diesel fuel or gas, will be needed
for peaking power
to keep the electricity grids stable when the production of renewable electricity, e.g. utilizing
wind or solar power, is increased.
The choice of the alternative, renewable fuels for engine
-
driven power plants and marine
applications is
at the moment quite narrow. The amount of renewables of all liquid fuels is at
present less than 2%. Biodiesels, FAMEs, have been studied for long time and apparently, despite
of the problems they may have, they are still in the great interest. One import
ant increment to the
category of alternatives is fuels that are produced from e.g. oil wastes, i.e., recycled fuels. They
are not renewable, but recycling of potential energy raw materials is still one step forward in
increasing the suitable and more susta
inable options.
To utilize the blends in medium
-
speed engines for power production, accurate knowledge of the
physical and chemical properties of fuel blends is very important for the optimization of engine
performance. The determination of the fuel kinema
tic viscosity is needed to create proper fuel
atomization. The injection viscosity affects directly the combustion efficiency and the engine
power. Consequently, this study focused on measuring kinematic viscosity curves for seven fuel
blends, as well as t
he neat fuels used for blending. The temperature range was 10
–
90
°C. The
fuels used for blending were rapeseed methyl ester, animal
-
fat based methyl ester, hydro
-
treated
vegetable oil, light fuel oil and marine gas oil produced from recycled lubricating oi
ls.
