摘要:
The invention provides a composition containing an oil of lubricating viscosity and an N-substituted malimide. The invention further relates to the use of the lubricating composition in an internal combustion engine.
摘要:
A composition of a major amount of an oil of lubricating viscosity; a secondary or tertiary amine being represented by the formula R 1 R 2 NR 3 wherein R 1 and R 2 are alkyl groups of at least 6 carbon atoms and R 3 is hydrogen, a hydrocarbyl group, a hydroxyl-containing alkyl group, or an amine-containing alkyl group; and a dispersant, provides high static coefficients of friction and a durable positive slope during oxidative and mechanical stressing, particularly as a friction component of an automatic transmission.

摘要:
A composition useful for lubricating an automatic transmission comprises an oil of lubricating viscosity and a hydrocarbyl amine with a hydrocarbyl group of 12 to 22 carbon atoms and having one or two additional groups of the structure -R3-NHC(O)R4, wherein R3 is an alkylene group of 1 to 4 carbon atoms and R4 is a hydrocarbyl group of 4 to 22 carbon atoms, or a nitrogen-containing heterocyclic group, or an aminoalkyl group. The hydrocarbyl amine does not contain a primary amino group.
