| Designers of internal combustion engines have useful equations for many of the factors influencing reliability and performance, but not for wear. In this investigation, a laboratory simulator was used to identify the important variables influencing cylinder bore wear. The same characteristics of wear were observed in the simulator as in running engines, even though the simulator did not attempt to duplicate all the conditions found within an engine. A new picture of wear in cylinders is presented, along with data showing the influence of several parameters. In particular, a strong effect from ring material was observed. |
