| Abstract(J) | 内燃機関におけるノッキングにおいて，様々な特性の圧力振動が生じることが知られている．しかし，それらの特性の違いが生じる理由については不明な点も多い．そこで，本研究では自着火挙動とノッキング特性の関係に着目し，筒内全域が可視化可能な２ストロークエンジンを用いて実験を行った．点火時期を変更し，異なるノッキング強度による指圧測定及びハイスピードカメラで燃焼挙動の撮影を実施し，測定結果の解析を行なった． Translation |
| Abstract(E) | In this study, we focused on the autoignition behavior and knocking characteristics. We observed the autoignition behavior in the entire bore area by using an optically accessible engine. The relationship between autoignition behavior and knocking characteristics was clarified by visualization images and frequency analysis of in-cylinder pressure. The result, the growth rate of autoignition was considered to have a significant effect on the knocking intensity. In addition, the ρ1,0 mode was dominant in the vibration mode caused by knocking regardless of the position of the autoignition, and the generation of multiple vibration modes was considered to increase the knocking intensity. |
