Zusammenfassung:	PROBLEM TO BE SOLVED: To estimate a fuel quality value of a fuel injected into a combustion engine.SOLUTION: A system includes a controller configured to control operations of a combustion engine, to receive a signal from at least one knock sensor coupled to the combustion engine, to determine a knock margin value from the signal, and to estimate a fuel quality value of a fuel injected into the combustion engine based at least on a comparison between the knock margin value and a laboratory performance data set.SELECTED DRAWING: Figure 1 【課題】燃焼エンジンの中へ噴射される、燃料の燃料品質値を推定する。【解決手段】システムは、コントローラーを含み、コントローラーは、燃焼エンジンの動作を制御し、燃焼エンジンに連結されている少なくとも１つのノックセンサーから信号を受信し、信号からノックマージン値を決定し、ノックマージン値と実験室性能データセットとの間の比較に少なくとも基づいて、燃焼エンジンの中へ噴射される燃料の燃料品質値を推定するように構成されている。【選択図】図１
