| Abstract(J) | 2サイクルガソリンエンジンにおいて，燃料にcyclohexaneが含まれるとノッキング強度が高くなることがある．本研究では燃料として用いる炭化水素の分子構造に着目し，cyclo系炭化水素を燃料としてノッキング強度を比較した．その結果，メチル基と二重結合がノッキング強度に及ぼす影響が明らかになった． Translation |
| Abstract(E) | Suppression of knocking in spark ignition engines is important for improving thermal efficiency. In a previous study, knocking intensity is higher than with other fuels of the same octane number when fuel containing cyclohexane is used in a 2 stroke cycle gasoline engine. Therefore, in this study, the relationship between molecular structure and knocking intensity was investigated. The results suggested that methyl groups in the molecule may reduce knocking intensity, while double bonds may increase it. Furthermore, compounds containing nitro groups were detected in the exhaust gas when fuel with high knocking intensity was used. |
