Aimed at load-carrying mechanism, systematic study was made on the functions of basic topological structures and some functional structures of the cylinder head, such as sprayer jacket, ports, strengthen rib, jobbing sheet, etc., in the load carrying system. Moreover, the deformation characters of these structures in the processes of carrying and transmitting loads were also thoroughly studied by the thesis.
