COMPUTATIONAL FLUID DYNAMICS SIMULATION OF A SINGLE CYLINDER RESEARCH ENGINE WORKING WITH BIODIESEL
Abstract
The main objective of the paper is to present the results of the computational fluid
dynamics simulation of a direct injection 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 engine control unit, 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. 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.
