CLEANER AND INCREASING OPERATIONAL PROPERTIES OF DIESEL FUEL
The existing technical means purification of diesel fuels can remove mechanical impurities and free water. Moreover, the range of the particulate contaminants to be removed in the cleaning process varies from 5 to 100 microns. However, the bulk of the contaminants in the fuel stored and used in agricultural machinery, comprise resins, asphaltenes, oxidation products and dissolved water, concentrated in the range of particle size of 0.1-1 microns. The aim of the research is the development of technology and equipment for cleaning of diesel fuels from all kinds of impurities, including dissolved water. One objective is to improve the working and low temperature lubricating properties cleaned fuel. As a result of theoretical and experimental studies failed to substantiate the optimal parameters of the purification process of fuel and hardware implementation. Specifically established that the technological process of cleaning should consist of two phases. At the first stage, the coagulation of impurities. On the second - the removal of impurities by centrifugation. An installation and cleaning technology can reduce the amount of impurities in the fuel is 80... 90%, improve the lubricating properties of the fuel, improve low temperature properties of diesel fuels in 25... 30 %.
