Available in PDF, EPUB and Kindle. Book excerpt: A high temperature apparatus has been developed for determining the wear characteristics of refractory materials for piston ring and cylinders in low heat loss advanced diesel engines. Operation of the apparatus has demonstrated good simulation with actual engine experience. Ceramic materials and coatings evaluated include zirconias, silicon carbide, silicon nitride, and two chromium oxides. Both liquid and solid lubricants have also been evaluated with ceramic materials in the apparatus.

Download or read book A Review of Sub Scale Test Methods to Evaluate the Friction and Wear of Ring and Liner Materials for Spark and Compression Ignition Engines written by and published by . This book was released on 2002 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: A review was conducted of past laboratory-scale test methods and to assess their validity for ranking materials and lubricants for use as piston and liner materials in compression-ignition (CI) and spark-ignition (SI) engines. Most of the previous work was aimed at simulating SI engine environments. This report begins with a discussion of the numerous factors that can affect the validity of an approach to simulating engine conditions in a laboratory. These include not only mechanical, chemical and thermal factors, but also human factors as regards how the vehicle is operated and maintained. The next section provides an annotated review of open literature publications that address the issues of laboratory simulation of engine components. A comparison of these studies indicates a lack of sufficient standardization in procedures to enable a systematic comparison of one publication to another. There were just a few studies that compared several laboratory test methods to engine test results, and these indicated that some test methods correlate, at least qualitatively, better than others. The last section provides a series of recommendations for improving the accuracy and validity of laboratory-scale simulations of engine behavior. It became clear that much of the engine wear damage occurs during start-up when the engine is cold, and this calls into the question the usefulness of test methods that attempt to simulate steady-state running conditions. It is recommended that a new standard test method, perhaps developed with the help of the ASTM wear and erosion committee, be developed. It would use cold start-up conditions in the presence of degraded oil, or simulated degraded oil.

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.
