The main objective of the paper is to present the results of the CFD
simulation of a DI single cylinder engine using diesel, biodiesel, or
different mixture proportions of diesel and biodiesel and compare the results
to a test bed measurement in the same functioning point. The engine used for
verifying the results of the simulation is a single cylinder research engine
from AVL with an open ECU, so that the injection timings and quantities can
be controlled and analyzed. In Romania, until the year 2020 all the fuel
stations are obliged to have mixtures of at least 10% biodiesel in diesel
[14]. The main advantages using mixtures of biofuels in diesel are: the fact
that biodiesel is not harmful to the environment; in order to use biodiesel
in your engine no modifications are required; the price of biodiesel is
smaller than diesel and also if we compare biodiesel production to the
classic petroleum based diesel production, it is more energy efficient;
biodiesel assures more lubrication to the engine so the life of the engine is
increased; biodiesel is a sustainable fuel; using biodiesel helps maintain
the environment and it keeps the people more healthy [1-3].
