| 抄録(英) | This study proposes an integrated methodology for predicting the backpressure performance of mufflers equipped with variable valves by combining experimental and analytical approaches. An airflow rig-based evaluation system was developed to replicate internal combustion engine (ICE) and hybrid electric vehicle (HEV) operating conditions. To enhance one-dimensional (1-D) simulation accuracy, a novel parameter extraction technique was introduced. Furthermore, the influence of thermal aging on valve spring torque was investigated, revealing its significant impact on backpressure characteristics. The proposed approach improves the correlation between simulation and experimental results, enabling more accurate backpressure predictions. This advancement supports optimized exhaust system design and reduces development time during the early stages of vehicle development. 翻訳 |
