| Abstract(J) | 低SAPS潤滑油を用いるディーゼル機関に対して，基準値を超える量の硫黄を含有する燃料が不正使用された場合には，潤滑油の酸化劣化が早期に進むことが懸念される．本研究では，ディーゼル機関用低SAPS潤滑油の酸化劣化に及ぼす燃料中の硫黄分の影響を，燃料混入潤滑油のISOT試験，およびSO2バブリング試験中の酸化劣化指標を計測することにより調査した． Translation |
| Abstract(E) | The use of a nonstandard diesel fuel beyond sulfur limit may accelerates the degradation of low SAPS lubricating engine oil. This study examines the effect of sulfur in a diesel fuel on the oxidative degradation of low SAPS lubricating oil. The temporal changes of oxidative parameters were measured during ISOT test of the lubricating oil diluted with diesel fuel, and SO2 gas bubbling test. ISOT test results show that the sulfur in contaminated fuel brings no effect to the oxidative degradation. On the other hand, the presence of 5ppm SO2 in bubbling gas accelerates the consumption of the antioxidant. |
