Title: LUBRICANT COMPOSITION
Abstract:
A lubricant composition for a compression-ignition internal combustion engine includes an amine and a detergent selected from metal sulfonates, phenates, salicylates, carboxylates, thiophosphonates, and combinations thereof. The amine has the following general structure: I wherein each of R1, R2, R3, R4, R5, R6, R7, R8, R9, and R10 is independently a hydrogen or a C1 through C3 hydrocarbon group, R11 is a C1 through C15 hydrocarbon group. The lubricant composition has a TBN of from about 10 to about 100 mg KOH/g when tested according to ASTM D2896. The amine contributes from about 0.1 to about 28% of the TBN of the lubricant composition. Further, a method of lubricating an internal combustion engine with the lubricant composition includes the steps of injecting a fuel and the lubricant composition into a cylinder to form a mixture, and combusting the mixture via compression-ignition.
