On the basis of the internal heat balance of CI engine with direct fuel injection, the quantity of heat transported during the combustion process from the combustion zone was determined. The real indicator diagrams are the bases for determination of the heat release Characteristics during the combustion process and making up of the internal heat balance. These diagrams were worked out for the engine fuelled with diesel oil for three sets of the injection timing and for work of the engine according to the full load engine Characteristics, and the load Characteristics taken at the engine speedb for the maximum engine torque. Tests with the three different injection timing were carried out. Tests with the load characteristics of the compression-igniting engine for five values of the power were carried out. The pressure in the cylinder of the engine during combustion process was recorded by means of liąuid cooled a piezo-electric quartz sensor with a load amplifier. Characteristics of heat release depended on the composition, temperature and the mol quantity of the working charge in the cylinder during the combustion process. Characteristics of the heat release were determined with the use of the novel calculation program. The program was worked out by authors at the assumption that the process of complete combustion was finished at the moment of the opening of the engine exhaust valve. For purpose of simplification calculation of the quantity of heat lost into the cooling system, the radiation, dissociation and incomplete combustion, were assumed to change during the combustion process in a linear way.
