Tartalmi leírás:
The environmental pollution and the decrease of the oil based fuels are the
greatest problems of the automotive-industry at the start of the 21st century. There were and
certainly there are a number of experiments to aiming substitute the petrol and the diesel oil
with other fuels. One group of these substitutable fuels is the bioethanol ? biodiesel ? diesel
oil mixtures. These mixtures are very similar to the fuels used today, as it can be used in the
engines without any structural changes.
At the Technical University of Budapest investigations have been made to explore the
possibility of using bioethanol ? biodiesel ? diesel oil mixtures in vehicles and agricultural
engines. The main aspects of the researches was find blends that are substitutable for diesel
oil consisting of the most renewable part as possible, reaching the same or similar power
output and lower the emissions.
The experimentations were based on mixing bioethanol and biodiesel with diesel oil. Our idea
was, when the biofuels are mixed they supplement each other, cutting the negative effect of
each and increasing the renewable component rate in the fuel. During the researches the two
main requirements of the fuel were: the maximal possible renewable part with which the
engine does not need any changes, yet meets the prerequisites set by diesel oil and to have the
same power and better emissions with the blend. The low (up to 20%) biofuel rate was
important, while the first step of introduction is possible with low rates.
The experiments were maid at engine benches with different engines, one-cylinder
measurements, cetin-number determination, viscosity determination, life cycle analysis and
cost benefit analysis.
In conclusion of the research it could be established that the use of bioethanol-biodiesel-diesel
oil emulsion in agricultural engines is in technicality already solved, as no changes are needed
on the engine, and it also reduces the emissions and is economically justified.
