Comprehensive assessment of the stages of creation and application of ethanol-fuel emulsions in diesel engines
Introduction. At the moment, there is no universal methodology with which it is possible to conduct a comprehensive assessment of the comparative technical and economic efficiency of the development and use of various types of alternative fuels. Materials and methods. When creating new EFCs, complex additives based on alkenyl succinimide C-5A and molybdenum disulfide MоS2, ethyl alcohol and commercial diesel fuel were used. The analysis of new structures for operation on EFC has been carried out. A model has been developed for comparative assessment of soot and NOx emissions from diesel engines. Economic calculations were carried out according to the original method. Results. The data on the creation of new EFCs with improved operational indicators are presented, the designs of systems to ensure the diesel engine can operate on EFCs, data on the improvement of the environmental performance of the diesel engine and the damage caused by toxic components emitted into the atmosphere from the diesel exhaust gas in the event of its transition to work with clean diesel fuel at VKKETE. Discussion. The practical use of VKKE as a fuel for diesel engines should be preceded by their development, development of supply and regulation systems, theoretical analysis and technical and economic assessment of the results of use. Conclusion. The development of new VKKETE and methods of their use can significantly improve the environmental performance of a diesel engine, reduce the consumption of deficient diesel fuel and reduce the damage caused by toxic components emitted into the atmosphere from the exhaust gas of a tractor diesel engine.
