Lubricant compositions for direct injection engines |
| abstract |
The present invention relates to a method for reducing the low-speed pre-ignition event of a spark ignited direct injection internal combustion engine by supplying a lubricant composition containing an oil of lubricating viscosity and an ashless antioxidant to a sump. The ashless antioxidant may be selected from phenolic compounds, aryl amine compounds and sulfurized olefins, and in particular 2,6-hindered phenols and diarylamine compounds. |
