Abstract
Description
(例えば、H/Wセンサ)出力、吸気温センサ出力、湿度センサ出力、大気圧センサ出力、及び前述のブロック101で計算されたエンジン回転数から、吸入空気中の乾燥空気量(または、乾燥空気流量)と水蒸気量(または、水蒸気流量)を計算し、更にブロック132で算出したEGRガス量と水蒸気分圧を考慮して吸気管内の乾燥空気分圧と水蒸気分圧を推定するとともに、その推定結果を用いてエンジンの動作条件をもとに、エンジンのシリンダ(気筒)に流入する空気量(シリンダ流入乾燥空気量)(及び、水蒸気量)を推定ないし演算するブロックである。ブロック103は、前述のブロック101で計算されたエンジン回転数、及び前述のエンジンのシリンダへ流入する空気量(シリンダ流入乾燥空気量)から、各領域におけるエンジンの要求する基本燃料及びエンジン負荷を表すエンジン負荷指標を計算する。ブロック103は、例えば、EGRガス量が相対的に大きい場合、特にそのうちのEGR水蒸気分圧が高い場合、シリンダ流入乾燥空気量は相対的に減少すると推定されるので、最適な空燃比を維持するために、エンジンの要求する基本燃料(量)が少なくなるように当該基本燃料(量)を算出する。一方で、EGRガス量が相対的に小さい場合、特にそのうちのEGR水蒸気分圧が低い場合、シリンダ流入乾燥空気量は相対的に増加すると推定されるので、最適な空燃比を維持するために、エンジンの要求する基本燃料(量)が多くなるように当該基本燃料(量)を算出する。すなわち、EGRガス量の増加(あるいは、減少)、特にそのうちのEGR水蒸気分圧の増加(あるいは、減少)に応じて、エンジンの要求する基本燃料(量)が少なくなる(あるいは、多くなる)ように、当該基本燃料(量)を算出する。また、本実施例においては、図4と同様、吸気管内の乾燥空気量を推定することで、基本燃料補正手段のブロック110に、図3に示した湿度補正手段を持たない構成としている。
