RÉSUMÉ

The article presentes a methodology for determining the characteristics of heat release in a self-ignition internal combustion engine based on real indicator diagrams. The proposed algorithm enables determining the total relative released heat quantity, the indicated relative released heat quantity, heat losses, and the indicated relative released heat quantity rate. The article reports the results of experimental tests of a self-ignition FIAT MultiJet 1.3 SDE 90 KM engine operating under full load conditions. During the operation of the engine, a single-, two-, and three-stage fuel injections were done. On the basis of the investigation carried out, the engine heat release characteristics have been determined and analyzed. The obtained investigation results indicate the possibility of using the multistage fuel injection for both shaping the characteristics of an internal combustion engine and reducing the emissions of harmful components in exhaust gases.
