Based on a series of experiments proved appropriate mechanisms for the temperature control of the working cylinder marine diesel (DM) when forcing through a gas turbine boost - this can significantly extend life cycle of a motor, its reliability and efficiency. As a result of forcing BOD work on the rise of temperatures and, as a consequence, the stress-strain state (SSS) of the working cylinder and associated elements of the cylinder group that, in turn, leads to the decrease of the main operational parameters of DM. As a means of managing VAT cylinder proposed modifications to the cooling system - this reduces the VAT level to acceptable values. To identify the needed parameters, control actions, a series of experiments to assess the thermal state of the engine cylinder (as in derated form, and forced). The engine was installed liner (2nd cylinder) prepared 24 standard chromel-kopelove thermocouples. The article presents the results of measurements of temperature of a cylinder of the engine, in its location in the vertical and horizontal positions. According to the results of measurements of the boundary conditions necessary for solution of the corresponding heat conduction problem. On the basis of experimental measurements and the results of their analysis of the expediency of modifying the schema cooling SD - combined on full flow circulation (with the supply of the refrigerant in the upper part of the cylinder block).
