Influence of Mixture Temperature and Equivalence Ratio on Reaction Products of n-heptane before Auto-ignition

混合気温度と当量比がn-heptane の自着火過程で生成される化合物に及ぼす影響

A comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometer (GC x GC - TOFMS) was used for analysis of gas composition in a constant volume combustion chamber before ignition. For mass spectrometer, electron ionization and field ionization were used in order to estimate molecular formula and identify chemical compounds. Reaction intermediates produced from n-C₇H₁₆/O₂/Ar mixture were analyzed in this study. About oxygen-containing hydrocarbons, it was suggested that the concentration of reaction products from φ=5.0 were more than 10 times as high as in comparison with those of φ=1.0. n-C₇H₁₆/O₂/Ar 混合気について,定容燃焼容器内に一定温度で3min 保持して火花点火を行った場合に火炎伝播速度とノック強度が最も高くなる温度条件の近傍で,当量比と火花点火前の混合気中に含まれる反応生成物の関係を飛行時間型質量分析計を備えた包括的2DGC(GC×GC-TOFMS)で分析した知見を報告する.
