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)
