Investigation of Robustness Control for Practical Use of Gasoline HCCI Engine

ガソリンHCCI エンジン実用化に向けた耐環境ロバスト制御の検討

In previous reports, robustness control logic for HCCI engine using crank angle sensor and knock sensor was discussed. Recently, ion current sensors have been started to use as a countermeasure against abnormal combustion for downsizing engines and high compression ratio engines. In a view point of the trend mentioned above, application of the ion current sensors to robustness control for HCCI was examined. In case of applied voltage 225V, correlation with indicated mean effective pressure, maximum pressure rise rate and ion signal were low. The cause was estimated that cylinder temperature (thermal ion) of HCCI was lower than one of spark ignition combustion.本報はHCCI ロバスト制御構築を目的としイオン電流センサを用いた燃焼状態検出技術を検討した.印加電圧の変更により検出感度を変更し実機試験を行った.その結果印加電圧225V において図示平均有効圧,最大圧力上昇率との相関は低く,この要因が低温燃焼によるサーマルイオンの抑制効果であることが分かった.
