摘要： Methods of reducing stochastic pre-ignition events and/or carbonaceous deposits in a gasoline-fueled engine by adding at least 10 ppm by weight of a compound having at least one alkyl succinic acid group to a gasoline fuel, wherein said compound is the product of (a) and (b), wherein:
(a) is an amine with at least one tertiary nitrogen, water, or a hydrocarbyl substituted alcohol; and
(b) is a hydrocarbyl-substituted succinic acid and/or anhydride.-

摘要： A cleaning composition, which is suitable for cleaning fuel delivery systems, air-intake systems, intake valves, and combustion chambers, includes at least 3 wt. % of a polyether component, at least 5 wt. % of a polar solvent, and at least 5 wt. % a non-polar solvent. The polyether component is selected from polyethers, polyetheramines, and mixtures thereof.

摘要： Fuel additive compositions having at least one acylated detergent, at least one Mannich detergent, and at least one polyether and/or polyetheramine. The acylated detergent may be the reaction product of a hydrocarbyl-substituted acylating agent and a nitrogen containing compound having at least one amino group, that may optionally be quaternizable, and at least one oxygen or nitrogen atom capable of reacting with the hydrocarbyl-substituted acylating agent. The compositions are useful for reducing the formation of carbonaceous deposits and/or cleaning carbonaceous deposits in an engine, such as a gasoline direct injection engine.
