| Abstract: | As marine engines'' intensification indexes getting higher, components working under high temperatures, like cylinder heads and pistons, and key friction pairs like piston rings,gas valves, and bea-rings are now working under more severe conditions. How to ensure the reliability of these components is the key in engine research and development. From the aspects of high reliability design of components working under high temperatures, friction design and flexible and variable technology, the latest research achievements of marine engine struture design are introduced. |
