    摘要:

    采用國際標(biāo)準(zhǔn)化組織和中國石化行業(yè)標(biāo)準(zhǔn)，考察了以三羥甲基丙烷酯（TMP）為主要成分的二沖程汽油機(jī)油基礎(chǔ)油的潤滑性能。研究表明，TMP在二沖程汽油機(jī)的運(yùn)行過程中具有良好的潤滑性能，且高溫粘度越高，潤滑性能越好；多種不同粘度TMP調(diào)合使用，具有增效作用，混合酯的潤滑性能超過單一成分的潤滑性能。用相同的潤滑性評定方法并不能考核酯基二沖程油中抗磨劑的作用。

    Abstract:

    According to the evaluating standards of two-stroke gasoline engine oil's lubricity published by ISO and Sinopec, the lubricity of two-stroke lubricant’s base oils that mainly constituted by trimethylol propane ester (TMP) has been investigated. The research results indicated that TMP had excellent high-temperature lubricity under the engine operating conditions. The lubricity was better when using higher high-temperature viscosity TMP. The mixed ester had better lubricity than any single composition in the mixture. But the effect of anti-wear additives on lubricity in ester base oils could not be investigated by the evaluating method of lubricity.
