Abstract:

A dispersant is prepared from an amine and a hydrocarbyl-substituted acylating agent, wherein the hydrocarbyl substituent is a polymerized olefin having a polydispersity {overscore (M)} /{overscore (M)} of greater than 5. Such polyolefin substituents are prepared by polymerization of olefins in the presence of a calcined catalyst comprising a partially or fully neutralized ammonium salt of a heteropolyacid.

International Classification:

F01L 902

US Classification:

123196R

Abstract:

This invention relates to a method of operating a spark ignition four-stroke internal combustion engine comprised of a valve train and a crankcase and equipped with an exhaust gas aftertreatment device, said method comprising: (A) operating said engine using a gasoline fuel composition, the exhaust gas from the operation of said engine being advanced through said aftertreatment device; (B) lubricating said crankcase using a first lubricating oil composition, said first lubricating oil composition optionally containing an extreme-pressure additive comprised of metal and phosphorus, provided the amount of phosphorus contributed to said first lubricating oil composition does not exceed about 0. 04% by weight based on the weight of said first lubricating oil composition; and (C) lubricating said valve train using a second lubricating oil composition. In one embodiment, the inventive method further comprises the following additional steps: (D) removing part of said first lubricating oil composition from said crankcase, said removed part of said first lubricating oil composition (i) being combined with said gasoline fuel composition and consumed with said gasoline fuel composition as said engine is operated or (ii) being combined with the exhaust gas from said engine and removed from said engine with said exhaust gas, said first lubricating oil composition being characterized by the absence of extreme pressure additives comprised of metal and phosphorus; and (E) adding an additional amount of said first lubricating oil composition to said crankcase to replace said removed part of said first lubricating oil composition.

US Classification:

123196R, 123 9033

Abstract:

This invention relates to a method of operating an internal combustion engine comprising a valve train, said method comprising: (A) operating said engine using a normally liquid or gaseous fuel; (B) lubricating components of said valve train using a solid film lubricant; and (C) lubricating said engine, including said components of said valve train, using a low-phosphorus or phosphorus-free lubricating oil composition, said low-phosphorus or phosphorus-free lubricating oil composition optionally containing an extreme-pressure additive comprised of metal and phosphorus, provided the amount of phosphorus contributed to said low-phosphorus or phosphorus-free lubricating oil composition by said extreme-pressure additive does not exceed about 0. 08% by weight based on the weight of said low-phosphorus or phosphorus-free lubricating oil composition. In one embodiment, the inventive method further comprises the following additional steps: (D) removing part of said low-phosphorus or phosphorus-free lubricating oil composition from said engine, said removed part of said low-phosphorus or phosphorus-free lubricating oil composition (i) being combined with said fuel and consumed with said fuel as said engine is operated or (ii) being combined with the exhaust gas from said engine and removed from said engine with said exhaust gas; and (E) adding an additional amount of said low-phosphorus or phosphorus-free lubricating oil composition to said engine to replace said removed part of said low-phosphorus or phosphorus-free lubricating oil composition.

International Classification:

F01L 902

US Classification:

123196R, 508293, 508554

Abstract:

This invention relates to a low-sulfur consumable lubricating oil composition, comprising: a base oil; an acylated nitrogen-containing compound having a substituent of at least about 10 aliphatic carbon atoms; and a sulfur content of about 5 to about 250 ppm; said composition being characterized by the absence of an extreme-pressure additive comprised of metal and phosphorus. This invention further relates to a a method of operating an internal combustion engine equipped with an exhaust gas after treatment device, said method comprising: (A) operating said engine using a normally liquid or gaseous fuel; (B) lubricating said engine using the foregoing low-sulfur consumable lubricating oil composition; (C) removing part of said low-sulfur consumable lubricating oil composition from said engine, said removed part of said low-sulfur consumable lubricating oil composition (i) being combined with said fuel and consumed with said fuel as said engine is operated or (ii) being combined with the exhaust gas from said engine and removed from said engine with said exhaust gas; and (D) adding an additional amount of said low-sulfur consumable lubricating oil composition to said engine to replace said removed part of said low-sulfur consumable lubricating oil composition.
