摘要：

       分析了汽油涡轮增压缸内直喷(TGDI) 发动机的润滑技术要求，通过发动机油的抗氧化、抗磨损、低速早燃、涡轮增压器沉积物和减摩节能等试验研究了直喷增压汽油机油的使用性能。结果表明：缸内直喷、涡轮增压等技术的使用对汽油发动机提出了全新的润滑要求，与传统发动机油相比，汽油直喷增压发动机润滑油需要更强的抗氧化和抗磨损性能，并能抑制涡轮增压器的沉积物，同时兼具减摩节能和抗低速早燃性能；针对全新的润滑要求，从润滑油配方设计角度提出了技术解决方案。

Abstract:

The lubrication requirements of turbocharging gasoline direct injection (TGDI) engine was analyzed, and the performance of TGDI engine oil was studied through the tests on the anti-oxidation, anti-wear, low speed pre-ignition, turbocharger deposit and friction reduction. The results show that TGDI engine puts forward fully new requirements on lubricant; By contrast of traditional engine oil, TGDI engine oil needs higher antioxidation, anti-wear performance, a high temperature deposits control, fuel friction reduction, and low speed pre-ignition. The solutions are also proposed for these issues on the side of oil formula to meet the lubricating requirements of TGDI engines.

Key words: turbocharging gasoline direct injection (TGDI), engine oil,  anti-oxidation, anti-wear, friction reduction, low speed pre-ignition (LSPI)
