Summary

A factorial-design test program was conducted to determine the effects of piston ring coatings, lubricants, contact stress and cylinder liner coatings on the frictional forces generated and material wear at simulated advanced diesel engine operating conditions. Statistical analysis of the frtctional forces revealed significant interactions between the lubricants and contact stresses. Interactions between liner materials and lubricants were also observed during analysis of wear volumes. It was shown that chrome oxide-based liner coatings yielded higher factional forces, and that the higher contact stress resulted in greater wear volumes.
