| Abstract: | Combined with the development process of Dongfeng own engine,the selection of polyurethane materials with high heat resistance was introduced systematically during trial-producing the plastic intake manifold,and the vacuum casting technology strategy was formulated.The overvoltage resistance and alternate load endurance test results were suggested that the reliability of plastic intake manifold trial sample could be significantly enhanced. |
