摘要：
In this study, the effect of micro-grooves on hydrodynamic lubrication characteristics between a piston ring and a micro-grooved cylinder liner is analyzed numerically. Elrod's universal equation satisfying JFO theory is adopted to predict the cavitation region properly and calculate the pressure distribution between a piston ring and a micro-grooved cylinder liner. The analysis is carried out by varying the shape, depth, length, width and location of micro-grooves during the full engine cycle. The results show that micro-grooves can make friction loss decrease in comparison with a non-textured cylinder liner.
