Abstract
The European Investigation Group CEC IGL-17 was created in order to classify existing valve train wear tests into categories, in an attempt to reduce the number of such tests that are required for approval of a new oil.
Among the 33 investigated manufacturers, 12 had special requirements in addition to the “industry-wide” recommendations API SE/SF or CCMC.
Thirty-nine test methods were studied dealing with overhead camshaft or low mounted camshaft/push rod engines. Furthermore 123 engine tests have been run with 4 CEC Reference Lubricants.
In order to reduce the number of valve train wear tests and based on this study, the group CEC IGL-17 has proposed the standardization of a SCUFFING test run with a gasoline engine.
