Download or read book Test Method to Evaluate Cylinder Liner Piston Ring Coatings for Advanced Heat Engines written by Kevin C. Radil and published by . This book was released on 1997 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: A tribological test method has been developed to assess candidate high temperature piston ring and cylinder liner coatings for advanced heavy duty diesel engines. A reciprocating test rig is employed to reproduce the boundary lubricated conditions existing at the piston ring-cylinder liner interface during top ring reversal (TRR). The test specimens are fabricated from commercially available piston rings and cylinder liners to facilitate direct comparisons with current diesel engines. A data acquisition system is used to collect coefficient of friction values. Coating performance is based upon calculated volumetric wear factors of the ring and liner as well as the friction coefficient. Baseline tests were conducted with chrome coated piston rings sliding on pearlitic gray cast iron cylinder liners while in the presence of a fully formulated engine oil. Friction measurements exhibited excellent repeatability throughout the entire test with average values ranging from 0.079 to 0.082. The mean of the ring and liner wear factors was 7.28 x 10 to the minus 10th power mm 3/N̂m and 2.62xl0 to the minus 8th power mm3/N̂m, respectfully and are in good agreement with values reported in the literature. These results indicate that the test method is capable of reproducing TRR conditions at the ring-liner interface of a diesel engine.

Book excerpt: This book contains advanced-level research material in the area of lubrication theory and related aspects, presented by eminent researchers during the International Conference on Advances in Tribology and Engineering Systems (ICATES 2013) held at Gujarat Technological University, Ahmedabad, India during October 15–17, 2013. The material in this book represents the advanced field of tribology and reflects the work of many eminent researchers from both India and abroad. The treatment of the presentations is the result of the contributions of several professionals working in the industry and academia. This book will be useful for students, researchers, academicians, and professionals working in the area of tribology, in general, and bearing performance characteristics, in particular, especially from the point-of-view of design. This book will also appeal to researchers and professionals working in fluid-film lubrication and other practical applications of tribology. A wide range of topics has been included despite space and time constraints. Basic concepts and fundamentals techniques have been emphasized upon, while also including highly specialized topics and methods (such as nanotribology, bio-nanotribology). Care has been taken to generate interest for a wide range of readers, considering the interdisciplinary nature of the subject.
Download or read book The Influence of Honing on the Wear of Ceramic Coated Piston Rings and Cylinder Liners written by Kevin C. Radil and published by . This book was released on 2000 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reciprocating wear tests were performed to investigate the effects of honing on the wear of ceramic coated piston rings and cylinder liners. The baseline or control cases consisted of testing ceramic coated rings against ceramic coated liner specimens whose surfaces were ground and lapped smooth. A second series of tests were performed with liner specimens with base and plateau honed surfaces. Test conditions were chosen to simulate the temperatures, pressures, and boundary lubricated conditions present at top ring reversal in a conventional diesel engine. Wear factor comparisons between the baseline cases and the tests with the honed liner specimens indicate that honing alone is not sufficient to ensure an improvement in ring and liner wear.

Book excerpt: The ever-increasing demands placed on combustion engines are just as great when it comes to this centerpiece-the piston. Achieving less weight or friction, or even greater wear resistance, requires in-depth knowledge of the processes taking place inside the engine, suitable materials, and appropriate design and manufacturing processes for pistons, including the necessary testing measures. It is no longer possible for professionals in automotive engineering to manage without specific expertise of this kind, whether they work in the field of design, development, testing, or maintenance. This technical book answers these questions in detail and in a very clear and comprehensible way. In this second, revised edition, every chapter has been revised and expanded. The chapter on "Engine testing", for example, now include extensive results in the area of friction power loss measurement and lube oil consumption measurement.
