摘　　要：选用150SN和聚α-烯烃调配成15W/30多级油基础油,添加多种添加剂试制成醇燃料发动机油。对基础油性能、添加剂及复合配方进行了一系列模拟试验,考察了试油遇甲醇、甲酸和水时的性能变化。1G2和L-38及西德燃用甲醇燃料发动机试验结果表明,试油有良好的抗磨、抗腐蚀和抗乳化性。Alcohols, as one kind of the most likely alternative automative fuels to petroleum products, have been investigated in many countries. A development programme for vehicles running on M100 methanol fuel has been conducted in China. A partial synthetic oil was selected as the base stock for multigrade engine oil 15W/30. The performance of the base stick, additives, and formulated oil was tested by a series of labortory simulating tests. An optimum oil formulation was adopted on the basis of detailed study on the effects of methanol, formic acid and water on the formulated oil. The oil has passed the Caterpillar 1G2 and L-38 engine tests. It has also been tested on the methanol fueled VW Santana engine. The test resluts show that the formulated oil can proviode excellent antiwear, anticor- rosion and demulsifying performance.
