| 摘 要： | 为考察甲醇汽油对发动机油低温性能的影响,通过向发动机油中添加甲醇汽油及其模拟燃烧产物甲酸、甲醛,分析其对油样的倾点、凝点、低温动力黏度的影响。结果表明:甲醇汽油及其模拟燃烧产物甲醛、甲酸对油样的倾点、凝点影响较小;随着甲醇添加量的增加,油样的低温动力黏度有增大的趋势;在甲酸质量分数为0.8%~1.2%时,油样的低温动力黏度值较大,但其增大的趋势平缓。因此甲醇汽油及其模拟燃烧产物对发动机油的低温性能影响不大。 |

| Abstract: | In order to study the effect of methanol gasoline on the low temperature performance of engine oil,methanol gasoline and its simulated combustion products of formaldehyde and formic acid were added into the engine oils,and the pour point,solidification point and low temperature dynamic viscosity of the oil samples were analyzed.The results show that the pour point and solidification point have little change with adding methanol gasoline and its simulated combustion products of formaldehyde and formic acid t... |
