DonNASA, Makeevka, Gorozhankin S . A. , Degtyarev V. and . , 2001 . , 110 s. Summary of lectures is intended for students studying the course "Theoretical foundations of heat engineering"The summary of lectures is devoted to the presentation of the theoretical foundations of heat engineering in a short and clear form, taking into account the study of the material by students of the specialty cars and automotive industry. The course, in addition to providing modern energy training for automotive engineers, has its own special method of generalized disclosure of material, which allows to focus on identifying broader patterns and new opportunities for energy development. The theoretical foundations of technical thermodynamics, the theory of heat and mass exchange, special attention is paid to the thermodynamic cycles of thermal machines. Provides general information on heat supply and the use of secondary energy resources, aimed at the most economical use of energy resources. The study of this course is necessary for a deep understanding of the physical essence of the thermodynamic processes of heat engines, a clear understanding of the patterns of energy transformations in internal combustion engines.
