- the lubricant composition may have a total base number (“TBN”) of from about 10 to about 100 mg KOH/g when tested according to ASTM D2896.
- TBN total base number
- the amine may contribute from about 0.1 to about 28% of the TBN of the lubricant composition.
- a method of lubricating an internal combustion engine with the lubricant composition is also disclosed.
- the method of lubricating an internal combustion engine 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.
- the lubricant composition may comprise an amine and a detergent.
- the lubricant composition can comprise one or more of the amine, i.e., a single type of the amine or more than one type of the amine.
- the amine may be basic, soluble in base oils and fuels, and chemically stable, yet does not produce ash when combusted (i.e., is ashless according to ASTM D 874 and as understood in the art).
- ashless refers to the absence of significant amounts of metals such as sodium, potassium, calcium, and the like.
- the amine neutralizes acid but does not form ash which, as described above, can damage engine components, reduce fuel economy, and ultimately reduce engine life.
- the amine effectively neutralizes acids because of its basicity.
- a minimal amount of the amine can be added to neutralize or “treat” fuel. That is, the amine can be used at a low “treat rate”.
- the basicity of the amine is quantified by its TBN. TBN can be calculated theoretically and can also be determined according to ASTM D2896 and/or ASTM D4739.
- the amine may have a TBN of greater than about 100, alternatively greater than about 150, alternatively greater than about 200, alternatively greater than about 400, alternatively from about 100 to about 700, alternatively from about 150 to about 700, alternatively from about 200 to about 700, alternatively from about 400 to about 700, alternatively about 150, alternatively about 160, alternatively about 230, alternatively, about 250, alternatively about 460, alternatively about 660, mg KOH/g when tested according to ASTM D4739.
- the lubricant composition also has a TBN.
- the various components of the lubricant composition e.g. the amine, the detergent, the dispersant, etc., contribute to the TBN of the lubricant composition.
- the lubricant composition has a TBN of from about 10 to about 150, alternatively from about 20 to about 90, alternatively from about 30 to about 90, alternatively from about 30 to about 80, alternatively from about 30 to about 70, alternatively from about 20 to about 50, alternatively from about 20 to about 40, alternatively from about 20 to about 35, alternatively from about 50 to about 70, mg KOH/g when tested according to ASTM D4739.
- the amine contributes less than about 29, alternatively less than about 28, alternatively less than about 27, alternatively less than about 26, alternatively, alternatively less than about 25, alternatively less than about 20, alternatively less than about 15, alternatively less than about 10, alternatively less than about 7, alternatively less than about 5, alternatively less than about 3, from about 0.1 to about 28, alternatively from about 0.1 to about 29, alternatively from about 0.1 to about 25, alternatively from about 0.1 to about 20, alternatively from about 0.1 to about 10, alternatively from about 0.1 to about 7, alternatively from about 0.1 to about 5, alternatively from about 0.1 to about 3, % of the lubricant composition.
- the TBN of the lubricant composition and the TBN contribution of the amine may vary outside of the ranges above, but are typically both whole and fractional values within these ranges. For example, when the amine contributes less than about 28% to the TBN of a lubricant composition having a TBN of 50 mg KOH/g, the amine contributes less than about 14 mg KOH/g to the TBN of the lubricant composition. The amine does not contribute substantially to the total TBN of the lubricant composition, but a small amount of the amine with a reduced amount of detergent, provide significant acid neutralization.
- the acid neutralization attained with a use of a small amount of the amine and a reduced amount of detergent may be at least comparable (and in some instances better) to the acid neutralization attained when using a larger amount of the detergent by itself.
- the amine may be selected from the group consisting of (I), (II), (III), (IV), and (V) as defined below:
- each of R 1 to R 9 are independently selected from a hydrogen, a C 1-6 branched or straight alkyl or a halogen; and R 10 is selected from hydrogen, hydroxy or a C 1-20 branched or straight alkyl; in certain embodiments, R 1 , R 2 , R 5 , R 8 , and R 9 are hydrogen and R 3 , R 4 , R 7 and R 8 are independently a C 1-3 alkyl; in certain embodiments, R 10 is a C 8-15 alkyl; in one embodiment, R 1 , R 2 , R 5 , R 8 , and R 9 are hydrogen; R 3 , R 4 , R 7 and R 8 are a methyl; and R 10 is a C 11 alkyl;
- R 1 and R 2 are independently selected from C 1-20 branched or straight alkyl; in certain embodiments, R 1 and R 2 are independently selected from a C 6-12 alkyl; in one embodiment, R 1 and R 2 are both a branched C 8 alkyl;
- each of R 1 and R 2 are independently selected from a hydrogen, a C 1-6 branched or straight alkyl or a halogen; m and y are independently an integer of 1 to 6 and n is 1 to 7; in certain embodiments, R 1 and R 2 are independently selected from a C 1-3 alkyl; in certain embodiments, m and y are independently an integer of 1-3; in certain embodiments, n is an integer or a fractional number of 2 to 6.5; in one embodiment, R 1 and R 2 are both a methyl and m and y are both 1; in one embodiment, n is 2.5; in one embodiment n is 6.1; in certain embodiments, the average molecular weight (average M n ) of amine (III) ranges from about 100 to about 500, from about 200 to about 450, or from about 230 to about 430, about 230, or about 430.
- R 1 , R 2 , and R 3 are independently selected from C 1-20 branched or straight alkyl; in certain embodiments, R 1 , R 2 and R 3 are independently selected from a C 6-12 alkyl; in one embodiment, R 1 , R 2 and R 3 are both a branched C 8 alkyl; and
- the amine may be selected from the group consisting of:
- the amines of structures (I)-(V) can be added to the lubricant composition in smaller quantities than amines having a lower TBN and to achieve the desired TBN value of the lubricant composition. That is, because of their structure and basicity, amine structures (I)-(V) are very efficient and have excellent solubility in the lubricant composition.
- the amine may be present in the lubricant composition in an amount of from about 0.01 to about 32, alternatively from about 0.1 to about 25, alternatively from about 0.1 to about 20, alternatively from about 0.1 to about 10, alternatively from about 0.1 to about 5, wt. % based on the total weight of the lubricant composition.
- the amount of amine may vary outside of the ranges above, but is typically both whole and fractional values within these ranges. Further, it is to be appreciated that more than one amine may be included in the lubricant composition, in which case the total amount of all the amine included is within the above ranges.
- the detergent comprises an overbased metal sulfonate, salicylate, or phenate, detergent.
- the detergent comprises an overbased metal sulfonate, such as calcium sulfonate.
- the detergent comprises a calcium sulfonate, salicylate, or phenate.
- the detergent comprises an overbased metal salicylate, such as calcium metal salicylate.
- the detergent comprises an alkyl phenate detergent.
- the detergent is an overbased calcium sulfonate.
- the calcium sulfonate has a calcium content of from about 6 to about 14, alternatively from about 8 to about 12, alternatively from about 6 to about 11, wt. % based on the total weight of said calcium sulfonate detergent and/or a TBN of from about 250 to about 550, alternatively from about 250 to about 450, alternatively from about 250 to about 350, mg KOH/g when tested according to ASTM D2896.
- the amine and the overbased calcium sulfonate detergent are present in a weight/weight ratio of from about 1:1 to about 1:30, alternatively from about 1:2 to about 1:15, alternatively from about 1:2.5 to about 1:10. The ratio may vary outside of the ranges above, but is typically both whole and fractional values within these ranges.
- the detergent typically includes metals such as sodium, potassium, calcium, and the like which can react to form ash. It is believed that inclusion of the amine in the additive composition reduces the amount of detergent required in the lubricant composition and reduces the total TBN of the lubricant composition required to be effective. Since the amine is ashless, and the amount of excess detergent, e.g. overbased detergent, which forms ash and plates out onto cylinder walls and other engine components, is reduced, the damaging effects of the overbased detergent are also reduced.
- metals such as sodium, potassium, calcium, and the like which can react to form ash.
- the detergent may be included in the lubricant composition in an amount of from about 0.1 to about 35, alternatively from about 0.1 to about 10, alternatively from about 0.1 to about 7.5, alternatively from about 0.1 to about 5, alternatively from about 1 to about 5, alternatively from about 1 to about 4, alternatively from about 1 to about 3, alternatively from about 1 to about 2.5, wt. % based on the total weight of the lubricant composition.

- the amount of detergent may vary outside of the ranges above, but is typically both whole and fractional values within these ranges. Further, it is to be appreciated that more than one detergent may be included in the lubricant composition, in which case the total amount of all the detergent included may be within the above ranges.
- the dispersant comprises a polyalkenyl succinic anhydride polyamine and/or a polyalkenyl succinimide polyamine. While not intending to be bound by theory, it is contemplated that the dispersant (e.g. the polyalkenyl succinic anhydride polyamine and/or the polyalkenyl succinimide polyamine), when present, contributes to the solubility of the amine in the base oil. Additional dispersants such as polybutenylphosphonic acid derivatives and basic magnesium, calcium and barium sulfonates and phenolates, succinate esters and alkylphenol amines (Mannich bases), polyalkene amines, and combinations thereof can also be included in the lubricant composition.
- the dispersant e.g. the polyalkenyl succinic anhydride polyamine and/or the polyalkenyl succinimide polyamine

- the dispersant may be included in the lubricant composition in amounts of less than about 15, less than about 12, less than about 10, less than about 5, or less than about 4, wt. %, each based on the total weight of the lubricant composition.
- the lubricant composition may also include a base oil.
- the base oil is classified according to the American Petroleum Institute (API) Base Oil Interchangeability Guidelines. That is, the base oil may be further described as one or more of five types of base oils: Group I (sulfur content >0.03 wt. %, ⁇ 90 wt. % saturates, viscosity index 80-120); Group II (sulfur content less than or equal to 0.03 wt. %, and greater than or equal to 90 wt. %, saturates viscosity index 80-120); Group III (sulfur content less than or equal to 0.03 wt. %, and greater than or equal to 90 wt. % saturates, viscosity index greater than or equal to 120); Group IV (all polyalphaolefins (PAO's); and Group V (all others not included in Groups I, II, III, or IV).

- the amount of antiwear additive may vary outside of the ranges above, but is typically both whole and fractional values within these ranges. Further, it is to be appreciated that more than one antiwear additive may be included in the lubricant composition, in which case the total amount of all the antiwear additives included may be within the above ranges.
- the lubricant composition may also include a pour point depressant. Any pour point depressant known in the art may be included.
- the pour point depressant is typically selected from polymethacrylate and alkylated naphthalene derivatives, and combinations thereof.
- the pour point depressant may be included in the lubricant composition in an amount of from about 0.01 to about 5, alternatively from about 0.01 to about 2, alternatively from about 0.01 to about 1, alternatively from about 0.1 to about 0.5, wt. % based on the total weight of the lubricant composition.
- the pour point depressant may be included in the lubricant composition in amounts of less than about 5, less than about 4, less than about 3, less than about 2, less than about 1, wt. %, each based on the total weight of the lubricant composition.
- the amount of pour point depressant may vary outside of the ranges above, but is typically both whole and fractional values within these ranges. Further, it is to be appreciated that more than one pour point depressant may be included in the lubricant composition, in which case the total amount of all the pour point depressants included may be within the above ranges.
- the lubricant composition may also include an antifoam agent. Any antifoam agent known in the art may be included.
- the antifoam agent is typically selected from silicone antifoam agents, acrylate copolymer antifoam agents, and combinations thereof.
- the antifoam agent may be included in the lubricant composition in an amount of from about 1 to about 1000, alternatively from about 1 to about 500, alternatively from about 1 to about 400, ppm based on the total weight of the lubricant composition.
- the antifoam agent may be included in the lubricant composition in amounts of less than about 1000, less than about 500, less than about 400, ppm, each based on the total weight of the lubricant composition.
- the amount of antifoam agent may vary outside of the ranges above, but is typically both whole and fractional values within these ranges. Further, it is to be appreciated that more than one antifoam agent may be included in the lubricant composition, in which case the total amount of all the antifoam agent included may be within the above ranges.
- the lubricant composition may additionally include one or more additives to improve various chemical and/or physical properties.
- the one or more additives include antioxidants, metal passivators, and viscosity index improvers.
- Each of the additives may be used alone or in combination. If included, the one or more additives can be included in various amounts.
- the lubricant composition comprises, consists essentially of, or consists of the amine, an API Group I oil(s), and a detergent comprising as over-based calcium sulfonate.
- the lubricant is substantially free of the detergent.
- substantially free refers to an amount of detergent (or other additive) less than about 5, alternatively less than about 4, alternatively less than about 3, alternatively less than about 2, alternatively less than about 1, alternatively less than about 0.01, alternatively about 0, wt. % based on the total weight of the lubricant composition.
- the lubricant composition can be further described as a fully formulated lubricant or alternatively as an engine oil.
- the terminology “fully formulated lubricant” refers to a total final composition that is a final commercial oil.
- This final commercial oil may include, for instance, antiwear additives, dispersants, detergents, and other customary additives.
- amine and the overbased calcium sulfonate detergent are present in a weight/weight ratio of from 1:1 to about 1:30, alternatively from about 1:2 to about 1:15, alternatively from about 1:2.5 to about 1:10.
- the ratio may vary outside of the ranges above, but is typically both whole and fractional values within these ranges.
- the amine when used in minimal amounts, e.g. contributing from about 0.1 to about 28% of the TBN of the lubricant composition, and in combination with an overbased calcium sulfonate detergent, has an unexpected effect on acid neutralization (as shown in the examples).
- the use of the amine decreases an amount (by weight) of overbased calcium sulfonate detergent required to neutralize acid by greater than about 25%, or even greater than about 50%. That is, the combined performance of the amine and overbased calcium sulfonate detergent allows for use of a minimal amount of amine in the lubricant composition and a significant reduction in the amount of the detergent in the lubricant composition.
- the amine provides excellent solubility in the lubricant composition. It is also believed that the various structural embodiments of the amine set forth above in combination with a detergent comprising a metal sulfonate and a polybutenyl succinic anhydride polyamine yields a homogenous lubricant composition which does not phase separate and/or yield a precipitate (has excellent solubility characteristics) even when stored for various times (e.g. 90 days) at various temperatures (e.g. ⁇ 4° C., 4° C., 45° C., or 60° C.). For example, in various embodiments, the lubricant composition remains homogeneous and does not phase separate when exposed to: a temperature of 60° C. for 90 days; a temperature of 45° C. for 90 days; a temperature of 4° C. for 90 days; and/or a temperature of ⁇ 4° C. for 90 days.
- the lubricant composition is ashless (or low ash).
- ashless as used herein to describe the lubricant composition refers to the lubricant composition including the amine, which is ashless, and therefore a lubricant composition including less detergent, which can contribute to ash formation.
- the lubricant composition may also be further defined as ashless or ash-containing, according to ASTM D 874 or as is known in the art.
- ashless refers to the absence of significant amounts of metals such as sodium, potassium, calcium, and the like.
- the lubricant composition is not particularly limited to being defined as ashless because use of the word ashless is intended to reflect use of the amine, which is ashless, and subsequent reduction of detergent, which can contribute to ash, in the composition and thus the lubricant composition could be interpreted as ash-containing, e.g. interpreted as a “reduced ash composition”.
- the subject disclosure also provides a method of lubricating an internal combustion engine.
- the method of lubricating an internal combustion engine 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.
- the fuel and the lubricant composition are injected into the cylinder at a ratio of from about 100:1 to about 1000:1, alternatively from about 200:1 to about 400:1.
- the lubricant composition and the components thereof, e.g. the amine, the detergent, etc. are set forth and described above.
- the fuel comprises sulfur, e.g. diesel fuel comprising sulfur.
- the lubricant composition is used in a diesel engine (also known in the art as a compression-ignition engine).
- Diesel engines are typically internal combustion engines that use the heat of compression to initiate ignition and burn the fuel and the lubricant composition is injected into the cylinder/combustion chamber.
- Compression-ignition engines lie in contrast to spark-ignition engines such as a gasoline (petrol) engine or gas engine (using a gaseous fuel as opposed to gasoline), which use a spark plug to ignite an air-fuel mixture.
- the combustion engine is further defined as a compression-ignition internal combustion engine for a marine vessel, i.e., a marine combustion engine.
- the combustion engine is further defined as a compression-ignition internal combustion engine for a train, i.e., a train or railroad combustion engine.
- a compression-ignition internal combustion engine for a train i.e., a train or railroad combustion engine.
- the ashless fuel additive is not limited to use in combustion engines for marine applications. Use of the ashless fuel additive in other combustion engines, for other applications, such as automobiles, trucks, aircraft, trains, motorcycles, scooters, ATVs, lawn equipment, etc., is also contemplated herein.
- a mixture comprising the combined fuel and lubricant composition may be injected/introduced into a cylinder of the internal combustion engine and combusted to move a piston and power the internal combustion engine.
- the fuel and the lubricant are combined in advance of injection into the cylinder.
- the fuel and the lubricant are injected separately into the cylinder.
- the fuel and lubricant are combined in the cylinder.
- Examples 1-6 are lubricant compositions according to the subject disclosure. Examples 1-6 include an amine, a detergent, and an API Group I oil, and are described in Table 1 below. Comparative Examples 1 and 2 are set forth for comparative purposes in Table 2 below. Examples 1-6 show that use of a small amount of the amine can drastically reduce the amount of detergent required to neutralize acid even though the total lubricant composition TBN of the examples of Table 1 is lower than the total lubricant composition TBN of the examples of Table 2.
- Examples 1-6 and comparative examples 1 and 2 are tested for corrosion in accordance with ASTM D665—Standard Test Method for Rust-Preventing Characteristics of Inhibited Mineral Oil in the Presence of Water.
- ASTM D665 Standard Test Method for Rust-Preventing Characteristics of Inhibited Mineral Oil in the Presence of Water.
- the protocol set forth in ASTM D665 is followed, with the exception that the water in replaced with 2N H 2 SO 4 and the test duration was 10 minutes.
- a steel rod is submerged in 300 g of each particular example composition in a reaction vessel at 60° C.
- the steel rod is submerged in the example composition and aged, with stirring, for 30 min.
- 2N H 2 SO 4 is added to the reaction vessel to form a reaction mixture and the steel bar is aged in the reaction mixture at a temperature of 60° C. for 10 minutes.
- Example 2 Example 3 Amine Structure Amine TBN (mg 158 232 461 KOH/g) ASTM D 2896 Amine TBN 1.6 2.3 2.3 Contribution (mg KOH/g) ASTM D 2896 Detergent TBN 25 25 25 Contribution (mg KOH/g) ASTM D 2896 Total Lubricant 26.6 27.3 27.3 Comp.
- the detergent was an overbased calcium sulfonate detergent having a TBN of about 300 mg KOH/g when tested according to ASTM D2896.
- Examples 1-6 which include the amine, neutralize the H 2 SO 4 and significantly reduce the amount of corrosion.
- Examples 1-6 have a lower TBN and include 50% less overbased calcium sulfonate detergent than Comparative Examples 1 and 2.
- a minimal amount of the amine allows for a significant reduction in the total base number of the composition, and a significant reduction in the amount of the overbased calcium sulfonate detergent.
- utilization of the amine in combination with the overbased calcium sulfonate detergent provides an enhanced effect on neutralization (as compared to the detergent by itself), and decreases the amount of ash formed since a lower amount of detergent is required.
