ＦＡＭＥによるエンジンオイルの希釈度を決定するための測定方法及び分析容器

摘要

For checking engine oil, especially containing rate of FAME, we provide a measuring device including a cylindrical and upright analysis vessel having a reading scale with which a surface boundary is measured. In the vessel, the engine oil is mixed with reagents including alcohol(s) and a demulsifier. And the decreased volume is checked as volume of the FAME contained in the engine oil.
