The paper presents the results of the influence of the use of ethanol-fuel emulsion as a fuel on the performance of the combustion process and the soot formation processes of a 4CH 11,0/12,5 automotive diesel engine with a combustion chamber of the CNIDI type. The influence of the installation angle of advance of fuel injection on the maximum pressure and maximum temperature of the gases in the cylinder, as well as the mass concentration of soot particles in the nominal operating mode, is considered. Alternative fuel has a great influence on the content of soot particles in the combustion products, and their quantity, in turn, has a significant effect on the emissivity of the flame. And the thermal tension of the details of the cylinder-piston group depends on these indicators.
