Technology of reducing greenhouse gas emissions for decarbonization and decreasing anthropogenic pressure on the environment

Abstract

The article is devoted to the study of technology for reducing greenhouse gases (carbon dioxide, nitrogen) emitted during the operation of internal combustion engines when various types of liquid fuels are burned in them to reduce the harmful anthropogenic impact on the environment. Based on statistical data, the work presents an analysis of the dynamics of local and global emissions into the atmosphere in recent years and preventive measures to reduce them for decarbonization. The work presents a mathematical model consisting of basic conservation equations that describe the combustion process of liquid fuels at high turbulence. The paper presents the results of computational experiments to determine optimal conditions for the combustion of liquid fuels (gasoline and heptane). A study of the atomization and combustion processes was carried out depending on the droplet injection rate in the combustion chamber at high turbulence. Optimal combustion parameters for gasoline and heptane were determined. Based on the computational experiments carried out, the temperature and dispersion characteristics of the fuel-air mixture, as well as the concentration fields of combustion products (CO₂, N₂ profiles) and the aerodynamics of two-phase flow for two types of liquid fuels were obtained. Based on the results obtained, optimal combustion modes for gasoline and heptane were determined, in which it is possible to organize rational combustion of fuels, reduce the number of harmful emissions released, and improve engine efficiency. The application of the obtained optimal parameters for the combustion of hydrocarbon liquid fuels in the combustion chambers of real heat engines will minimize the anthropogenic load on the surrounding atmosphere with the release of greenhouse gases, promote decarbonization in the energy sector, and reduce the carbon footprint.
