| Abstract:Based on the analysis of existing internal combustion engine valve cam’s theoretical and technical shortcoming, the deformed hyperbolical function cam profile equation with continuous n order derivative and the major structure parameters and working parameters as independent variables was created which featured simple calculation. And the evaluation procedures for optimal design of the cam profile and the manufacturing simulation software for the valve cam were developed. The developed ICE deformed hyperbolic function valve cam has unique excellent features such as better high speed and stability, a larger fullness coefficient, softer vibration and noise. The application shows that the cam with the new profile could enhance the diesel’s dynamic functions and economic performance, debase its vibration, noise and exhausting pollution and help to achieve high speed, high performance, long life of internal combustion engine. |
