description: Topic of the final qualification work: "Computational study and optimization of the thermally stressed state of the piston of a forced gasoline engine with direct fuel injection". The work is devoted to the study of thermal stress, as one of the types of mechanical stress, as well as a decrease in the thermal stress of the working piston of an automobile highly accelerated gasoline engine. Research objectives: 1. Calculation of the engine workflow in various modes. 2. Calculation of the emotionality of the piston in various modes. 3. Improved piston design. 4. Performance analysis of the improved pistonIn the course of the study in this work, thermal calculations of the working process were carried out using the PROCESS program, in addition, using satellite programs, data were obtained on convective heat transfer in the engine combustion chamber, as well as in the area of ââââpiston rings. After building a solid model of the piston in the SolidWorks program, thermal, load and deformation analyzes of the piston were carried out in the AnsysWorkbench program. In the course of this study, certain methods were identified to reduce the thermal stress of ICE pistons, which were applied to improve the piston. The result of the work is confirmation of the operability of the engine piston with direct fuel injection using cooling of the internal cavity, as well as an oxidized fire bottom.
