Résumé:
The cylinder bore surface texture widely produced by honing technique, is an essential factor
for a good engine performance (friction, oil consumption, running-in, wear…). This explains
the improvement and development of various new honing techniques. These different honing
processes generate surfaces with various texture features characteristics (roughness, valleys
depth, crosshatch angle…).
This paper addresses a comparison of ring-pack friction for cylinder surfaces produced
respectively by plateau honing and helical slide honing. It takes in consideration the mutual
effect of superficial plateau roughness amplitude and honing angle. A numerical model is
developed to predict friction within the cylinder ring-pack system in mixed lubrication
regime. The results show the effectiveness of helical slide honed surface texture in
comparison to plateau honed bore surfaces.
