| Abstract: |
| With the stricter emission regulations and the crisis of fossil fuels, fuel efficiency and reliability of internal combustion engines are attracting more and more attention. The piston rings and cylinder liner friction pair are the primary source of the friction loss and wear failure in internal combustion engines. Cylinder liner honing texture is a special surface structure with a bi-Gaussian distribution that is designed to improve piston rings and liner tribological properties. Although the homogenization method and image rotation method have been used in the modeling of cylinder liner honing surface, homogenization-based modeling of the cylinder liner honing surface can not consider the actual distribution characteristics of the rough surface, while the method based on image rotation can generate a surface with a given orientation and synthesize it by superposition as a cylinder liner honing texture requires a rotated image area larger than the target area, which is not easy to handle. In addition, the Patir & Cheng flow factor determined based on the Gaussian distribution assumption is usually used for the lubrication analysis of piston rings and cylinder liners, while the honed surface of the actual cylinder liner is bi-Gaussian distribution, which is not applicable. |
