Abstract

　エンジンオイルの劣化および酸化防止性能を安価にかつ精度良く推定でき、それにより、エンジンオイルの劣化および交換時期を適切に判定できるエンジンオイルの劣化推定装置および酸化防止性能の推定装置を提供する。 　このエンジンオイルの劣化推定装置は、ＥＣＵ２を備える。ＥＣＵ２は、エンジンオイルの酸化防止性能ＯＩＴおよび清浄維持性能ＴＢＮを推定するとともに、推定した酸化防止性能ＯＩＴおよび清浄維持性能ＴＢＮに基づいて、エンジンオイルの劣化を推定する。酸化防止性能の推定装置もまた、ＥＣＵ２を備える。このＥＣＵ２は、エンジンオイル中の燃料の濃度［ＦＵＥＬ］を取得するとともに、取得した燃料濃度［ＦＵＥＬ］に基づいて、エンジンオイルの酸化防止性能ＯＩＴを推定する。
