Results are described of calculation-experimental investigations of cylinder liners having both smooth and ribbed cooling surfaces. The groove boring is shown to decrease the liner wall thickness, increase of the cooling surface area and turbulence of the sprinkler flow. These factors effect the temperature of the heat adopting liner wall of the engine 8Ch14/13 when operating under conditions of the nominal power. This temperature was decreased by about 8% which was followed by the piston temperature decrease, and thus by increase of the time interval between the motor oil replacement and the engine life.
