Документ Improving the performance of diesel engines fueled with water-fuel emulsion(Polish Scientific Society of Combustion Engines, 2023) Samoilenko, Dmytro; Savchenko, Anatolii; Kravchenko, SerhiiDue to unique properties, production and operation features, water-fuel emulsion (WFE) could be considered as one of the most promising type of alternative fuels for diesel engines. Experimental research showed that compared to traditional diesel fuel, application of water-fuel emulsion allows to reduce nitrogen oxides and soot emissions, which is due primarily to a decrease in the level of maximum temperatures in the engine cylinder, as well as a more uniform distribution of fuel over the combustion chamber volume thanks to its secondary disper-sion (micro-explosion phenomena). To control the stability of water-fuel emulsion properties during engine operation it is recommended to install water content sensor in the fuel supply system.Документ Research and Innovation to Improve the Efficiency of Modern Diesel Engines(IntechOpen, 2022) Marchenko, Andriy; Parsadanov, Igor; Pylyov, Volodymyr; Osetrov, Oleksandr; Linkov, Oleh; Kravchenko, Serhii; Trynov, Oleksandr; Meshkov, Denys; Bilyk, Serhii; Savchenko, Anatolii; Rykova, Inna; Rasoul, AryanModern diesel engines are one of the main mobile energy sources and are characterized by a high degree of workflow completeness, design, and manufacturing technology. The chapter summarizes the authors’ experience in improving diesel engines, increasing specific volume power, and reliability, ensuring a low level of environmental pollution emissions. The results of research using industry 4.0 technologies for systematization, choice of directions, and the search for rational ways to improve the efficiency of diesel engines are presented. The application of anergoexergy method for analyzing the efficiency of the working process of the engine and its systems is considered. Taking into consideration the operating conditions, technical solutions are proposed to improve the reliability of the most heat-stressed parts of high-powered engines. The possibilities for a comprehensive assessment of the fuel efficiency and environmental qualities of diesel engines have been expanded taking into account CO2 emissions when using traditional, alternative, and hybrid diesel fuel.
