Abstract
【解決手段】ベース筒内容積を学習値により補正することにより補正筒内容積を算出する。補正筒内容積を与えるクランク角とベースクランク角との差であるクランク角補正値を算出し、ベース点火時期をクランク角補正値およびフィードバック補正値により補正する。前回の燃焼において燃焼割合が設定割合となるクランク角における筒内容積である前回筒内容積VFpを算出し、前回の燃焼におけるベース筒内容積VBpに対する前回筒内容積VFpの偏差ΔVFpを算出し、学習値ΔVLを筒内容積偏差VFpに基づいて更新する。
【選択図】図15
Description
図2に示されるように各カムシャフト54,55を夫々反対方向に回転させるために駆動モータ59の回転軸には夫々螺旋方向が逆向きの一対のウォームギア61,62が取付けられており、これらウォームギア61,62と噛合する歯車63,64が夫々各カムシャフト54,55の端部に固定されている。この実施例では駆動モータ59を駆動することによってピストン4が圧縮上死点に位置するときの燃焼室5の容積を広い範囲に亘って変更することができる。なお、図1から図3に示される可変圧縮比機構Aは一例を示すものであっていかなる形式の可変圧縮比機構でも用いることができる。
