Definitions
- the present invention relates to the field of lubricating compositions, and more particularly to the field of lubricating compositions intended for the lubrication of marine engines, in particular two-stroke or four-stroke marine engines. It relates more particularly to the use of spiro compounds as detergent additives in lubricants for marine engines.
- the invention provides access to a lubricant with excellent detergency and oxidation stability properties, while maintaining a low ash content.
- Marine engines such as two-stroke or four-stroke marine engines, use lubricants, also called “marine oils", ensuring the lubrication of the various parts of the engine.
- lubricants also called “marine oils”
- slow two-stroke marine engines with a crosshead implement on the one hand, "cylinder” oils ensuring the lubrication of the piston-cylinder assembly or of the piston-segment-liner zone and, on the other hand , “system” oils, ensuring the lubrication of all moving parts other than the piston-cylinder assembly or outside the piston-ring-liner assembly.
- lubricating oils in particular cylinder oils.
- the lubricating oils within the piston-cylinder assembly are in contact with the combustion residues of the fuel, these residues possibly containing, when they come from fuels with a high sulfur content, significant quantities of acid gases.
- acid gases are formed: these are in particular sulfur oxides (SO2, SO3), which are then hydrolyzed, during contact with the humidity present in the gases. combustion and/or in oil, to generate sulfurous (HSO3) or sulfuric (H2SO4) acid.
- the neutralization capacity of lubricating oils was thus a criterion of choice, making it possible to adjust the basicity of the lubricant used to the sulfur content of the fuel used, in order to be able to neutralize all the sulfur contained in the fuel and likely to be transformed into sulfuric acid by combustion.
- base number or BN or "Base number” in Anglo-Saxon terminology, sometimes called TBN for “Total Base Number” in Anglo-Saxon terminology
- TBN Total Base Number
- the desired basicity for the lubricant was conventionally provided by detergents overbased with insoluble metal salts, in particular metal carbonates such as calcium carbonate.
- detergents are in particular metallic soaps of the salicylate, phenate, sulphonate or carboxylate type, which form micelles in which the particles of insoluble metallic salts are kept in suspension.
- Part of the BN can also be provided by non-overbased or “neutral” metallic detergents.
- a clogged filter due to unburnt matter can induce an increase in fuel consumption and thus result in fuel wastage, which goes against the desired properties in terms of reducing marine fuel consumption.
- lubricants for marine engines being in direct contact with the engine, and in particular with the hot part of the engine, such as for example the piston-cylinder assembly, have good stability at high temperatures, in order to reduce or prevent the formation of deposits on the surface of metal parts, which are harmful to the engine.
- document WO 2014/180843 proposes a cylinder lubricant for a marine engine, usable both with fuel oils with a high sulfur content and fuel oils with a low sulfur content, and having in particular good thermal resistance, combining a metallic detergent overbased with metal carbonate salts, a neutral detergent and a specific BN fatty amine, in particular a tetra-amine.
- Applications WO 2018/220007 and WO 2018/220009 propose, for example, the implementation of compounds derived from salicylic acid, products of the reaction between salicylic acid, a boron compound and an amine compound, for example of the polyamine, for formulating lubricating compositions for marine engines, in particular for engines marine two-stroke, combining good anti-corrosion properties, wear resistance and good detergency performance.
- the present invention aims to provide a means for providing a lubricant intended for the lubrication of a marine engine with excellent detergency properties while having a low impact on the ash content.
- the invention relates, according to a first of its aspects, to the use, as a detergent additive in a lubricating composition intended for a marine engine, for example a two-stroke or four-stroke engine, of at least one spiro compound of the following formula (I) [Chem 1] in which :
- M is an atom chosen from boron (B) and aluminum (Al), in particular is a boron atom; ni and n2 are, independently of each other, 0, 1 or 2; And
- R represent, independently of one another, a hydrocarbon group comprising from 1 to 50 carbon atoms, in particular from 5 to 20 and more particularly from 5 to 20 carbon atoms.
- the spiro compound used according to the invention is of formula (I) above, in which M is a boron atom.
- the spiro compound is a compound called a "spiroboronate compound", of formula (!') below: wherein n1, n2 and R are as previously defined.
- detergent additive within the meaning of the present invention, is meant a compound which, introduced into a lubricating oil, makes it possible to provide and/or increase its detergency capacities and therefore to reduce, prevent, or even remove engine deposits.
- spiro compound according to the invention will more simply denote a spiro compound of formula (I) as defined above, in particular a spiroboronate compound of formula (!') as defined above. Examples of spiro compounds considered according to the invention are described more precisely in the following text.
- marine lubricant refers to a lubricant intended for the lubrication of a marine engine.
- the marine lubricants under consideration according to the invention are suitable for use in the lubrication of two-stroke or four-stroke marine engines, in particular for two-stroke marine engines.
- a lubricant called “cylinder lubricant” used for lubricating the piston-cylinder assembly of the engine a lubricant called “system lubricant”, used for lubricating all parts in motion of the engine excluding the piston-cylinder assembly, or even a lubricant called “crankcase lubricant” used for the lubrication of the entire engine, including the piston-cylinder assembly, in particular in an engine 4-stroke.
- cylinder lubricant used for lubricating the piston-cylinder assembly of the engine
- system lubricant used for lubricating all parts in motion of the engine excluding the piston-cylinder assembly
- crankcase lubricant used for the lubrication of the entire engine, including the piston-cylinder assembly, in particular in an engine 4-stroke.
- the invention also relates, according to another of its aspects, to a lubricating composition intended for the lubrication of a marine engine, in particular a two-stroke or four-stroke engine, comprising at least:
- a lubricating composition according to the invention comprises, in addition to the said spiro compound(s) according to the invention, one or more other detergent additives, in particular chosen from the metallic detergent additives conventionally used in the field of lubricants, in particular based on calcium or magnesium.
- a spiro compound according to the invention makes it possible to obtain a marine lubricant having equivalent, and even improved, thermal resistance properties, compared to a lubricant incorporating conventional metallic detergents, and therefore to ensure good engine cleanliness, in particular of the segment-piston-cylinder area.
- the detergency properties of the marine lubricant can be assessed by evaluating the performance of the lubricant in terms of thermal resistance by ECBT type tests, as described in the publication entitled “Research and Development of Marine Lubricants in ELF ANTAR France - The relevance of laboratory tests in simulating field performance” by Jean-Philippe ROMAN, MARINE PROPULSION CONFERENCE 2000 - AMSTERDAM - 29-30 MARCH 2000.
- said spiro compound or compounds, implemented as detergent additives according to the invention generate little ash compared to conventional metallic detergents.
- the incorporation in a marine lubricant of one or more spiro compounds according to the invention advantageously makes it possible to increase the detergency capacities of the lubricant, without negatively impacting the content of ash generated by the lubricant.
- a lubricating composition according to the invention thus makes it possible to combine excellent detergency properties and a low level of ash, in particular sulphated ash.
- the implementation of a spiro compound according to the invention thus makes it possible to access a marine lubricating composition having good properties in terms of engine cleanliness, in particular in the segment-piston-cylinder zone of a marine engine, in particular the piston-cylinder assembly.
