Abstract
The aim of this study was to evaluate the influence of honing grooves on the formation of a lubricating film in gray cast iron piston cylinder liners. For this, a deterministic numerical model was used to analyze the mid-stroke region, where the greatest friction losses are located due to the shear stress of the lubricating fluid. Different distances between the surface of the piston cylinder liner and an idealized lubricating oil control ring were evaluated, considering the influence of surface roughness through the modified Reynolds equation implemented in the numerical model used. The range of distances studied using the dimensionless separation parameter
