EGR equipped diesel engines and lubricating oil compositions |
| 摘要 |
Soot induced kinematic viscosity increase of lubricating oil compositions for diesel engines, particularly heavy duty diesel engines, equipped with EGR systems, particularly EGR systems operating in a condensing mode, can be ameliorated by addition of a phenylenediamine compound. |

1. A diesel engine provided with an exhaust gas recirculation system, said engine being lubricated with a lubricating oil composition comprising a major amount of oil of lubricating viscosity, from about 0.04 to about 0.8 mass % of one or more phenylenediamine compound and from about 0.1 mass % to about 5 mass % of at least one ashless antioxidant compound selected from the group consisting of hindered phenol compounds, diphenylamine compounds, and mixtures thereof.
