Abstract
An additive gel for fuels that reduces the soot content in lubricating oil and/or emission in an engine. Further a process employing an additive gel for fuel in a fuel system to decrease the amount of soot in the lubricating oil of an engine and/or decrease the emissions from an engine.
Claims16
A composition comprising a gel used in an application selected from the group consisting of decreasing the amount of soot in the lubricating oil engine, decreasing the amount of emissions in the engine exhaust and combinations thereof;
- wherein the emissions reduced are selected from the group consisting of soot, NOx, hydrocarbons and combinations thereof;
- and
- wherein the gel comprises a detergent, an ashless succinimide dispersant and an antioxidant, where the ratio of detergent to dispersant is of about 10:1 to about 1:10, and wherein the gel has a tan delta value of less than or equal to 0.75;
- and
- wherein the composition further comprises at least one fuel additive selected from the group consisting of friction reducing agents, anti-misting agents, cloud-point depressants, pour-point depressants, mineral or synthetic oils, anti-knock agents, lead scavengers, dyes, cetane improvers, rust inhibitors, bacteriostatic agents, gum inhibitors, fluidizers, metal deactivators, demulsifiers, anti-icing agents, lubricity additives, friction modifiers, viscosity improvers, flow improvers, low temperature improvers, anti-static agents, valve-seat recession agents, intake valve deposit control additives, combustion chamber deposit control additives, fuel injector deposit control additives and combinations thereof;
- and
- wherein the composition further comprises one or more fuel-borne catalysts comprising organometallic compounds of Na, K, Co, Ni, Fe, Cu, Mn, Mo, V, Zn, Be, Pt, Pa, Ce, Cr, Al, Th, Se, Bi, Cd, Te, Sn, Ba, B, La, Ta, Ti, W, Zn, Ga, Pb, Ag, Au, Os, Ir and combinations thereof in the fuel.
A process comprising contacting in the range of a portion to all of the components of a gel composition with a fuel in an engine during the use of the engine such that at least a portion of all of the components of the gel are present in the combustion chamber of the engine resulting in the reduction of soot in the engine oil, emissions in the engine exhaust and combinations thereof and wherein the emissions reduced in the exhaust are selected from the group consisting of soot, NOx, hydrocarbons and combinations thereof;
- and
- wherein the gel composition comprises a detergent, an ashless succinimide dispersant and an antioxidant, where the ratio of detergent to dispersant is of about 10:1 to about 1:10, and wherein the gel has a tan delta value of less than or equal to 0.75;
- and
- wherein the composition further comprises at least one fuel additive selected from the group consisting of friction reducing agents, anti-misting agents, cloud-point depressants, pour-point depressants, mineral or synthetic oils, anti-knock agents, lead scavengers, dyes, cetane improvers, rust inhibitors, bacteriostatic agents, gum inhibitors, fluidizers, metal deactivators, demulsifiers, anti-icing agents, lubricity additives, friction modifiers, viscosity improvers, flow improvers, low temperature improvers, anti-static agents, valve-seat recession agents, intake valve deposit control additives, combustion chamber deposit control additives, fuel injector deposit control additives and combinations thereof.
A process comprising contacting in the range of a portion to all of the components of a gel composition with a fuel in an engine during the use of the engine resulting in the reduction of soot in the engine oil and/or emissions in an engine exhaust;
- and
- wherein the gel composition comprises a detergent, an ashless succinimide dispersant and an antioxidant, where the ratio of detergent to dispersant is of about 10:1 to about 1:10, and wherein the gel has a tan delta value of less than or equal to 0.75;
- and
- wherein the composition further comprises at least one fuel additive selected from the group consisting of friction reducing agents, anti-misting agents, cloud-point depressants, pour-point depressants, mineral or synthetic oils, anti-knock agents, lead scavengers, dyes, cetane improvers, rust inhibitors, bacteriostatic agents, gum inhibitors, fluidizers, metal deactivators, demulsifiers, anti-icing agents, lubricity additives, friction modifiers, viscosity improvers, flow improvers, low temperature improvers, anti-static agents, valve-seat recession agents, intake valve deposit control additives, combustion chamber deposit control additives, fuel injector deposit control additives and combinations thereof.
A fuel filter for an engine fuel system comprising a housing, a filter for removing particulate matter from a fuel filter and a container with a gel wherein the gel comprises a dispersant, a detergent, and an antioxidant and results in the reduction of soot, emissions or combinations thereof from an engine;
- and wherein the emissions reduced are selected from the group consisting of soot, NOx, hydrocarbons and combinations thereof;
- and wherein the gel has a tan delta value of less than or equal to 0.75.
A gel containment device for a fuel system comprising a housing in a fuel system and a container with a gel in the housing, and wherein the gel comprises a dispersant, a detergent and an antioxidant for the soot reduction, emissions reduction or combinations thereof from an engine;
- and wherein the emissions reduced are selected from the group consisting of soot, NOx, hydrocarbons and combinations thereof;
- and wherein the gel has a tan delta value of less than or equal to 0.75.

- wherein the emissions reduced are selected from the group consisting of soot, NOx, hydrocarbons and combinations thereof;
- and wherein the gel has a tan delta value of less than or equal to 0.75.
An internal combustion engine comprising;
- a) an internal combustion engine,
- b) a liquid fuel at 20° C.,
- c) a gel comprising a dispersant, a detergent and an antioxidant,
- d) a reservoir containing the gel and supplying the gel composition to the fuel in the fuel system of the engine resulting in soot reduction, emissions reduction or combinations thereof;
- wherein the emissions reduced are selected from the group consisting of soot, NOx, hydrocarbons and combinations thereof;
- and wherein the gel has a tan delta value of less than or equal to 0.75.
