Reliability and Robustness Analysis of Engine Ring-Pack Performance

Reduction of development time and improvement in product quality and reliability have been a driving force in the extremely competitive automotive industry. These trends require extensive use of Computer Aided Engineering (CAE) tools coupled with design optimization and analytical robustness and reliability tools. In this paper the Cylinder kit Analysis System for Engines (CASE), a CAE tool for predicting ring-pack performance in an automotive engine, has been integrated with the design optimization and analytical robustness and reliability tool (iSIGHT) for improving ring-pack performance, reliability, and robustness. A prototype engine has been analyzed and design recommendation tested with available manufacturing.
