Description
図7は、低負荷領域におけるエンジンの動作範囲を示す図である。低負荷領域では、点火時期の進角量は、燃費悪化の観点から最適点火時期によって制限され、遅角量は安定限界で制限される。外部EGR率の増加と共に、燃費最良点火時期と安定限界にはさまれる点火時期の設定可能範囲は減少する。外部EGR率は、この点火時期の設定可能範囲の中で最大値となる点で最も内燃機関の効率が高くなるが、わずかにEGR率や点火時期がずれただけで安定限界や燃費最良点火時期を超えてしまうため、外乱に対するロバスト性が低くなる。このため、点火時期の設定可能範囲を確保しつつ、外部EGR率を制御することが重要である。
また、制御部(CPU20e)は点火タイミングを設定された点火進角限界まで進角させた後、点火タイミングを遅角させた状態において、内燃機関(エンジン100)の燃焼安定限界に達していない場合には、点火タイミングを再度、進角させるとともに排気再循環量を増加させるように制御することが望ましい。また、制御部(CPU20e)は点火タイミングを設定されたノック限界まで進角させた後、点火タイミングを遅角させた状態において、前記内燃機関の燃焼安定限界に達していない場合には、点火タイミングを再度、進角させるとともに排気再循環量を増加させるように制御することが望ましい。
