Development of Cylinder Head Assembly of Rotary Valve Engine Based on 3D Printing Technology

Based on 3D printing technology, a cylinder head assembly of rotary valve engine was developed and trial- produced in this paper. The structure of the assembly, the lubrication system, sealing system and cooling system are designed. Using 3D metal printing technology, the production of sample blank is completed, and the machining centre is used to complete the finishing of parts. The structural rationality of the design and the feasibility of 3D metal printing are verified by the installation. This study can provide some reference for the design and development of new power system.
