Zero-dimensional Knock Modeling and the Livengood-Wu Integral
０次元ノックモデルとLivengood-Wu 積分
Zero-dimensional analysis with detailed kinetic mechanisms has been performed to elucidate the underlying chemistry of the Livengood-Wu integral which has been used to predict and analyze the knocking phenomena in spark ignition engines. Its predictive potential was ascribed to be the similarity between the concentration of the "pertinent reaction product (x)" in the original concept and the simulated logarithmic total concentration of hydroperoxides, log[total-OOH]. It was shown that the integral is a good indicator of ignition for periods before cool flames while the predictability significantly deteriorated for periods after cool flames.高過給希薄燃焼などの限界条件においてLivengood-Wu積分によるノック予測には限界があると言われるが，これを化学反応モデリングから詳細に検討した例はない．本発表では0次元のノックモデル・圧縮自着火モデルを用いてLivengood-Wu 積分の意味と適用限界について検討した結果を報告する．
