Definitions
- the present invention is applicable to the field of lubricants. More particularly, the present invention relates to the use of a lubricating composition with a high molybdenum content and comprising a combination of at least two compounds comprising molybdenum of different chemical nature. The lubricating composition simultaneously exhibits good fuel economy properties and good storage stability properties.
- the present invention also relates to a method of lubricating a mechanical part. The present invention relates to a method for reducing the energy losses by friction of a mechanical part.
- the use of a lubricating composition to reduce fuel consumption is also another object of the present invention.
- Improving the energy performance of lubricating compositions can be obtained in particular by mixing specific additives such as friction modifiers, viscosity index improving polymers, in base oils.
- organometallic compounds comprising molybdenum are commonly used. It is necessary for a lubricating composition to have good anti-friction properties that a sufficient amount of molybdenum is present.
- molybdenum dialkyldithiocarbamate hereinafter referred to in the present application by the acronym Mo-DTC is the most used as a source of molybdenum.
- this compound has the drawback of inducing the formation of sediment when the lubricating composition has an excessively high content of molybdenum element.
- the poor solubility of this compound modifies or even deteriorates the properties of the lubricating composition, in particular its viscosity.
- an excessively or insufficiently viscous composition is detrimental to the movement of moving parts, to the correct starting of an engine, to the protection of an engine when it has reached its operating temperature, and therefore ultimately causes in particular an increase in fuel consumption.
- An objective of the present invention is to use a lubricating composition which overcomes all or part of the aforementioned drawbacks.
- Another objective of the invention is to use a lubricating composition the formulation of which is easy to use.
- Another objective of the present invention is to provide a lubrication method allowing energy savings.
- a subject of the invention is thus the use of a lubricating composition
- a lubricating composition comprising at least one. base oil, at least one molybdenum dithiocarbamate (Mo-DTC) compound, least one molybdenum dithiophosphate compound (Mo-DTP) and in which the amount of molybdenum supplied by the Mo-DTP compound and the Mo-DTC compound ranges from 1000 to 2500 ppm by mass relative to the total mass of the lubricating composition and in which the amount of molybdenum supplied by the Mo-DTC compound is greater than or equal to 500 ppm and is strictly less than 900 ppm by mass relative to the total mass of the lubricating composition.
- the lubricating composition has a viscosity index greater than or equal to 140.
- lubricating composition within the meaning of the present invention, is meant a lubricating composition, and not a grease.
- the additives are not dissolved but dispersed in the network of fibers formed by the soap.
- the problem of solubility of Mo-DTC does not arise as in oils, in particular for motor oils, in which solubility is imperative.
- the lubricating compositions according to the invention are not greases.
- the applicant company has found that, in a lubricating composition having a molybdenum content which ranges from 1000 to 2500 ppm and comprising a Mo-DTC compound, the addition of at least one Mo-DTP compound makes it possible to dissolve the Mo-DTC compound and simultaneously makes it possible to improve the fuel-saving properties of said composition.
- the amount of Mo supplied by the Mo-DTC compound must strictly be less than 900 ppm in the lubricating composition relative to the total mass of the lubricating composition.
- the present invention makes it possible to use lubricating compositions with a high molybdenum content and in which the Mo-DTC compounds are soluble, that is to say they can be dissolved in the lubricating composition without forming a precipitate or without making it cloudy.
