Influence of feeding an agricultural engine with E-diesel and BioE-diesel fuels on chosen parameters of its work

Aim of project
The aim of the project is to know and present the problems concerning the influence of the properties of E-diesel and BioE-diesel fuels on fast-changeable parameters of the agricultural diesel engine and the process of warmth emission and to carry out studies on the character and values of changes in basic eff ective parameters of its work when powered with the above mentioned fuels. Another cognitive aim will be the assessment of infl uence of powering the engine with the above mentioned fuels on the emission of CO2, CO, HC, NOx and PM and the assessment of the amount of soot in the sprayer in comparison with an engine powered with diesel fuel.

The final result of the examinations and analyses, will be working out the optimal composition of ethanol, diesel or ester, fuel-enriching additives in E-diesel and BioE-diesel, directed at the achievement of the greatest possible effectiveness of the examined engine at the lowest possible emission of toxic exhaust fumes and essential control changes in the engine.

Expected results
Experimental analysis of using the above mentioned biofuels obtained from ethanol and enriching additives and diesel with possible supplements of esters of methylic acids of rape oil RME will enable to formulate an answer to the following questions:

On the differences in the process of injection, burning and warmth emission of the engine powered with E-diesel and BioE-diesel fuels compared with feeding the engine with mineral fuels;

On the effectiveness of the functioning of the engine powered with the above mentioned fuels;

On the influence of the change in the angle of overtaking injection on the quality of the process of burning when powering the engine with E-diesel, BioE-diesel fuels;

On the values of pressures in the injection wire, in the combustion chamber and the temperature of the working substance compared with classical mineral fuel or 100% ester at the same working conditions of the examined engine;

On whether feeding with the above mentioned fuels influences a decrease of emission of toxic exhaust fumes with keeping the energy parameters the same as for classical mineral fuel or 100% of ester;

On whether the composition of the worked out E-diesel or BioE-diesel fuel will enable to get better low-temperature properties in comparison with pure mineral classical fuel or 100% ester;

On the influence of the change of the angle of overtaking injection, doses of fuel, pressures of injection on the work of the engine;

On whether the examined fuels will have better greasing properties than those of classical mineral fuel, which positively infl uence durability of the fuel system.
