Abstract

The paper analyzes the main directions for improving the energy efficiency of marine diesel power plants and reducing atmospheric air pollution from exhaust gases. Numerical study of fuel spraying characteristics by diesel injectors at injection pressures in the range from 50 to 300 MPa has been conducted.
Based on the analysis of the known designs of thermally insulated combustion chambers, the technology of manufacturing a pilot piston is proposed, which is based on the application of a ceramic coating using zirconium dioxide powder on the walls of the combustion chamber of the mass-production piston.
