| Abstract(J) | HCNG燃料を用いた火花点火エンジンにおいて,水素混合がノッキングに及ぼす影響を実験および数値解析により検討した.水素混合によりノッキング強度は増大する一方,開始時期への影響は小さいことを確認した.そして反応経路解析から,HO₂/H₂O₂系を介した自着火時の酸化反応の活性化が主因であることを示した. Translation |
| Abstract(E) | The effects of hydrogen addition on knocking characteristics in a spark-ignition engine fueled with HCNG were investigated through experiments and numerical analysis. The results showed that hydrogen enrichment increases knocking intensity, while its effect on knock onset timing is limited. To investigate the underlying mechanism, reaction pathway analysis was conducted. The analysis indicates that enhanced oxidation reactions during autoignition via the HO2/H2O2 reaction system are primarily responsible for the increased knocking intensity. |
