Effect of Heat Release Pattern during Flame Propagation on Auto-ignition Process of End-gas
火炎伝播時の発熱過程がエンドガスの圧縮および自着火過程に及ぼす影響
The unburned mixture gas near the combustion chamber wall (end-gas) is compressed by the piston and the expansion of burned gas. So the process leading to the auto-ignition of the end-gas is affected by the heat release pattern of the flame during propagation. Though the spark timing is fixed, the heat release of the flame fluctuates. In other words, several heat release patterns are included under the steady state engine operation condition. In this study, how the heat release patterns of the flame affect to the auto-ignition process of the end-gas has been investigated by using zero-dimensional chemical kinetic simulations.SI機関の熱効率向上を阻害するノッキングは非定常な現象で毎サイクル必ず発現するとは限らない．また伝播火炎の火炎帯からの発熱もサイクル毎に変動し壁面近傍で圧縮される未燃ガスはこの変動の影響を受ける．本研究では火炎伝播時の熱発生パターンがエンドガスの自着火過程に及ぼす影響について考察する．
