Abstract
This work presents the results of the study of the effect of water in the dissolved state in diesel fuel, as well as in the form of a water-fuel emulsion. The question of the expediency of using modified diesel fuel is being considered. Experimental data show that a decrease in the intensity of nitrogen oxides formation occurs due to the transfer of diesel fuel from fuel oil to a water-fuel emulsion. The use of an emulsion has the effect of reducing the volume of active zones of nitrogen oxide formation, and also reduces the maximum local gas temperatures. As a result of the conducted studies of water-fuel systems on the 1H 15/18 engine, in which water molecules were in a dissolved state in the form of true solutions. To improve the solubility of water, modifiers of various nature (high-molecular alcohol and quaternary ammonium base salt) were introduced into diesel fuel. During the research, it was found that the presence of dissolved water in the upgraded fuel leads to a decrease in the amount of toxic pollutants CO and NOx in the exhaust gases.
