- Abstract
- In practice of internal combustion engines during simulation of three-dimensional temperature fields of parts of combustion chamber the solutions, obtained in theory of thin plates and shells, extensively are used. For this purpose in the complex-shape parts of combustion chamber are selected the simpler elements, which on one side, determine thermal condition, reliability of these parts, on the other - with a sufficient precision they approach geometry of thin plates and shells. In particular, for the cylinder cover the fire bottom, which it is possible to represent in the form of plate or disk with the openings under the valves and the injector, i.e., to reduce it to the calculated form, characteristic for this theory, is such element.
