Definitions
- the present invention is applicable to the field of lubricants, and more particularly to the field of lubricants for marine engines, especially for two-stroke marine engines. More particularly, the present invention relates to a marine engine lubricant comprising at least one base oil and at least one fatty amine.
- the lubricant according to the invention has a high basicity reserve which results in a high BN (or Base Number) and can be used with both high sulfur content fuels and low sulfur fuel oils.
- the lubricant according to the invention has a sufficient neutralization capacity vis-à-vis the sulfuric acid formed during the combustion of high-sulfur fuel oil and a risk of increasing its reduced or nonexistent viscosity, while by limiting the formation of deposits at high temperature.
- the lubricant according to the invention can also be characterized by a low BN value and thus be usable with very low sulfur content fuels, while presenting a risk of increasing its reduced or non-existent viscosity and limiting the formation of high temperature deposits.
- the present invention also relates to a method for lubricating a marine engine, and more particularly to a two-stroke marine engine using this lubricant.
- the present invention also relates to a method for reducing the formation of deposits in the hot parts of a marine engine, in particular a two-stroke marine engine, comprising contacting said hot parts with a lubricant comprising a fatty amine.
- the marine oils used in two-stroke slow-cycle engines are of two types: the cylinder oils on the one hand, ensuring the lubrication of the cylinder piston assembly, and the system oils on the other hand, ensuring the lubrication of all the moving parts other than those of the cylinder piston assembly.
- the combustion residues containing acid gases are in contact with the lubricating oil.
- Acid gases are formed during the combustion of fuel oils; these are in particular oxides of sulfur (S0 2 , SO 3 ), which are then hydrolysed during contact with the moisture present in the combustion gases and / or in the oil. This hydrolysis generates sulfurous acid (HS0 3 ) or sulfuric acid (H 2 SO 4 ).
- these acids must be neutralized, which is usually done by reaction with the basic sites included in the lubricant.
- the neutralization capacity of an oil is measured by its BN, characterizing its basicity. It is measured according to ASTM D-2896 and is expressed in equivalent weight of potash per gram of oil or mg of KOH / g of oil.
- the BN is a classic criterion for adjusting the basicity of cylinder oils to the sulfur content of the fuel used, in order to neutralize the sulfur contained in the fuel, and likely to be converted into sulfuric acid by combustion and hydrolysis.
- BN marine oils ranging from 5 to 100 mg KOH / g oil are available on the market.
- This basicity is provided by detergents which are overbased by insoluble metal salts, especially metal carbonates.
- the usual overbased detergents intrinsically have a BN conventionally comprised between 150 and 700 mg of potash per gram of detergent. Their mass content in the lubricant is determined according to the BN level to be reached. Part of the BN can also be provided by non-overbased or "neutral" detergents of BN typically less than 150 mg of potash per gram of detergent.
- the insoluble metal salts of the overbased detergents for example calcium carbonate, thus contribute significantly to the BN of the usual lubricants.
- the detergent part itself or soaps, found in both neutral and overbased detergents, typically provides the bulk of the BN complement.
- Environmental concerns have led, in some areas and particularly in coastal areas, to limit the sulfur content in fuel oils used on ships.
- MARPOL Annex 6 (Regulations for the Prevention of Air Pollution Ships) Regulations of ⁇ (International Maritime Organization) entered into force in May 2005. It sets a maximum sulfur content of 4.5% by weight relative to the total weight oil for heavy fuel oils and the creation of controlled emission zones of sulfur oxides, called SECAs (SOx Emission Control Areas). Heavy fuel oils are high viscosity fuels mainly used by large diesel engines installed on board ships.
- SECAs sulfur Emission Control Areas
- ECAs emission Control Areas
- marine lubricants having a BN in the order of 70 mg KOH / mg of lubricant are mainly used.
- marine lubricants having a BN of the order of 40 mg KOH / mg of lubricant may be mainly recommended .
- each of these lubricants has limitations of use for the following reasons: the use of a BN cylinder lubricant 70 mg KOH / g lubricant in the presence of a low sulfur fuel oil (1% by weight relative to the total weight of the fuel oil and less) and fixed lubrication rate, creates a large excess of basic sites and a risk of destabilization micelles of unused overbased detergents, which contain insoluble metal salts. This destabilization can result in the formation of insoluble metal salt deposits (eg calcium carbonate) and having a high hardness, mainly on the piston ring, and eventually can lead to a risk of excessive wear of polishing shirt.
- insoluble metal salt deposits eg calcium carbonate
- a BN cylinder lubricant 40 mg KOH / g of lubricant does not provide sufficient neutralization capacity to the lubricant in the presence of a high sulfur fuel oil and thus can lead to a significant risk of corrosion.
- the optimization of the cylinder lubrication of a two-stroke engine then requires the selection of a lubricant whose BN is adapted to the sulfur content of the fuel used and the operating conditions of the engine. This optimization reduces the operating flexibility of the engine and requires a significant technical crew in the definition of the conditions in which the change of one type of lubricant to another must be achieved.
- the application WO2009 / 153453 describes the use of fatty amines in a marine lubricant for 2-cycle engines and can be used with high and low sulfur fuel oils.
- No. 3,814,212 relates to a lubricating composition comprising a polyamine having at least 12 carbon atoms.
- the lubricating composition may also include other additives such as mineral oil.
- the lubricant composition described herein is not a marine engine lubricating composition.
- this composition does not include neutral and / or overbased detergents.
- the lubricant which is in direct contact with the engine, and especially with the hot parts of the engine such as the segment segment / pistons / jacket (or SPC), must have increased temperature resistance and thus minimize or prevent the formation deposits in these hot parts.
- a marine lubricant especially for a two-stroke marine engine, which can have a high BN, especially close to or equal to 100 or a low BN, especially close to or equal to 25, while having increased temperature resistance and thus a low risk of deposit formation in the hot parts of the engine.
- a lubricant for a marine engine especially for a two-stroke marine engine, having no or very little risk of increasing viscosity over time, and in particular during its use.

- Another object of the invention is to provide a lubricating composition for minimizing or preventing the formation of deposits in the hot parts of a marine engine.
