The paper considers features of high viscosity heavy fuel RMG380 (500) hydrodynamic treatment using a four-chamber homogenizer. A finely dispersed and homogeneous mixture of fuel and water is formed as a result of sudden change in nozzles outflow velocity and a pressure drop in vacuum chamber, and mixing occurs due to the passage of emulsion through the holes at ultrasonic vibrations chamber outlet. Modernization scheme of the marine fuel supply system for preparing and using water-fuel emulsions in two-stroke marine diesel engines has been developed. The use of a four-chamber homogenizer ensures grinding structure of fuel organic part, size reduction of resins agglomerates and asphaltenes, as a result, the combustion rate in cylin- ders increases.The results of operational tests of the main marine engine using water-fuel emulsions based on heavy fuel RMG380 are presented. The use of water-fuel emulsions with a water content of 12% allows to reduce fuel consumption by improving the quality of mixture formation, reduce carbon formation and slow down the nitrogen oxidation. Considered physical reasons for positive influence of water-fuel emulsions on the economic and environmental indicators of diesel engine.
