Accuracy Improvement of Cylinder Head Gasket Seal Performance Prediction Technology for Model-Based Development

Abstract

We work on improving the technology for predicting the gas seal performance of head gasket. Among them, I would like to judge the difference in the engine evaluation results with different rubber materials. In order to consider deterioration during engine evaluation, we focused on the reduction of rubber thickness. We have developed a new unit evaluation method to quantitatively judge the reduction of rubber thickness. The evaluation conditions are based on analysis results that simulate engine evaluations. New prediction technology that combines these showed the same results as the engine evaluation.
