A Computational Study of the Combined Effects of EGR and Boost Pressure on HCCI Combustion Process

EGR および過給がHCCI 燃焼過程におよぼす影響

This study computationally investigates the combined effects of EGR and boost pressure on HCCI combustion process for n-heptane under the condition of constant amount of fuel. The computations were conducted using the single-zone model of CHEMKIN-PRO with detailed chemical-kinetics mechanisms for n-heptane from Lawrence Livermore National Laboratory. Contribution matrix on heat release of elementary reactions is employed to better understand underlying mechanisms of EGR and boost pressure on HCCI combustion process by extracting important elementary reactions. Using contribution matrix on heat release of elementary reactions, it is possible to chemically explain the combined effects of EGR and boost pressure on HCCI combustion process.N-heptaneを対象にEGRおよび過給がHCCI燃焼特性に及ぼす影響を素反応数値計算により調査した.雰囲気のパラメータとして圧縮開始時の温度,圧力に加えて酸素濃度[mol/m3],酸素モル分率[mol/mol],比熱比,熱容量,火炎温度,当量比等が燃焼過程に及ぼす影響を系統的,体系的に検証する.
