the boundary conditions of heat transfer  in the working cavity of the cylinder head  of the four-stroke internal combustion engine

This article describes the proposed model by specifying the boundary conditions of the thermal load of the cylinder head of a high-powered diesel or gas engine, based on common methodological basis. Concerted discrete models cylinder head and body cavities is the combustion chamber, the exhaust channels and cavities of the cooling, allow end-to-end modeling of all processes that simplifies the procedure of calculation of parameters capacity for heads work and increases the accuracy and reliability of the results.
