The focus of this article is to research technology for reducing greenhouse gas emissions, such as carbon dioxide and nitrogen, produced by internal combustion engines when liquid fuels are burned in them to minimize humans’ negative 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 mathematical model is based on basic conservation equations that explain the liquid fuels combustion process in high turbulence. The paper outlines the outcomes of computational experiments that were carried out to determine the best conditions for the combustion of liquid fuels (petrol and heptane). The droplet injection rate in the combustion chamber at high turbulence was analyzed to determine the atomization and combustion processes. Optimum combustion parameters for petrol and heptane were identified. The temperature and dispersion characteristics of the fuel-air mixture, along with the concentration fields of combustion products such as CO2 and N2, and the aerodynamics of multiphase flow for two types of liquid fuels were determined through computational experiments. The optimum combustion modes for petrol and heptane were determined based on the attained results, which can facilitate rational fuel combustion, reduce the number of released harmful emissions, and enhance engine efficiency. Implementing the optimum parameters that were achieved for the combustion of hydrocarbon liquid fuels in the combustion chambers of actual 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.
