Title: Numerical optimization of ring-pack behavior

Abstract:

The ring-pack behavior in a modern gasoline engine represent complicated phenomena. The process of ring-pack design consists of two stages: understanding the physical behavior and design synthesis on the systematic manner. Computer models give an inside on the physical processes associated with the ring-pack behavior. Mathematical optimization techniques provide the tools for design synthesis on the systematic way based on an optimal criteria.

The mathematical optimization technique was developed and applied or ring-pack design synthesis. When applied to the existing engine ring-pack designs, the optimized results indicated the potential for significant reduction in blow-by through the ring-pack by optimizing ring-pack geometry. The optimization results were compared with the original ring pack designs for two gasoline engines for a wide range of operating conditions.
