摘要:
A lubricant composition including a base oil and from 0.01 to 10 wt. % of an amine compound based on a total weight of the lubricant composition. The amine compound has the formula R1(R2)NH, where R1 and R2 are each independently straight or branched chain acyclic alkyl groups having from 1 to 20 carbon atoms. The alpha carbon of R1 or R2 is primary if R1 or R2 is an alkyl group having more than one carbon atom respectively. At least 90 wt. % of the amine compound remains unreacted in the lubricant composition based on a total weight of the amine compound prior to any reaction in the lubricant composition.
摘要:
A lubricant composition including a boroxine compound is disclosed. An additive package including the boroxine compound is also disclosed. The lubricant composition and the additive package may additionally include an amine compound. The boroxine compound of the lubricant composition acts to improve compatibility of the lubricant composition with a fluoropolymer seal.
摘要:
A lubricant composition for a compression-ignition internal combustion engine comprises: (i) an amine as an ashless fuel additive having a total base number (“TBN”) of from about 200 to about 600 mg KOH/g when tested according to ASTM D2896; and (ii) a detergent selected from metal sulfonates, phenates, salicylates, carboxylates, thiophosphonates, and combinations thereof. The lubricant composition has a TBN of from about 20 to about 130 mg KOH/g when tested according to ASTM D2896, The amine contributes greater than about 30% of the TBN of the lubricant composition. Further, a method of lubricating an internal combustion engine with the lubricant composition comprises the steps of injecting a fuel and the lubricant composition into a cylinder to form a mixture, and combusting the mixture via compression-ignition.

摘要:
A lubricant composition including an epoxide compound is disclosed. An additive package including the epoxide compound is also disclosed. The epoxide compound of the lubricant composition acts to improve compatibility of the lubricant composition with a fluoropolymer seal and improve the total base number of the lubricant composition.
摘要:
This disclosure is directed to an additive package for a lubricant composition that provides improved fluoropolymer compatibility. The additive package comprises an amine compound and a seal compatibility additive. The disclosure is also directed to a lubricant composition comprising a base oil, an amine compound, and a seal compatibility additive. The seal compatibility additive improves the fluoropolymer seal compatibility of the resultant lubricant composition.
