HIGH TEMPERATURE LUBRICATION REQUIREMENTS OF EUROPEAN GASOLINE AND DIESEL ENGINES FOR CARS

A CEC Investigation Group has examined temperatures in European gasoline engines. Forecasts indicated sump temperatures would increase by 10-15 C, partly related to emissions control systems. Consequent problems were predicted as wear scuffing, oil oxidation, ring sticking, high oil consumption, and bearing/seal distress. Development targets for lubricant high temperature performance tests are discussed. A similar CEC Survey concerned high-speed diesel engines. High temperature oil performance test needs for the smaller car diesel engine are discussed in the light of problems identified in the survey.
