Overview of Techniques for Measuring Friction Using Bench Tests and Fired Engines

摘要

This paper presents an overview of techniques for measuring friction suing bench tests and fired engines. The test method discussed have been developed to Provide efficient, yet realistic, assessments of new Component designs, materials, and lubricants for in- Cylinder and overall engine applications. A Camero-Plint Friction and Wear Tester was modified To permit ring-in-piston-groove movement by the test Specimen, and used to evaluate a number of a cylinder Bore coatings for friction and wear performance.
