Definitions
- the present invention relates to the field of lubricating compositions and base oils for motor vehicles.
- the invention provides a lubricating composition for an engine, gearbox or vehicle bridge.
- This lubricant composition comprises an oil soluble polymer which is a particular polyalkyl glycol or polyalkylene glycol (PAG).
- the invention also relates to the use of this lubricant composition for reducing the fuel consumption of a vehicle equipped with an engine, a bridge or a gearbox lubricated with this lubricant composition or this PAG. particular.
- the conditions of use of gasoline engines and diesel engines include extremely short journeys as well as long journeys. In fact, 80% of the journeys of Western European cars are less than 12 kilometers while vehicles cover annual mileages of up to 300 000 km.
- the emptying intervals are also very variable, from 5,000 km for some small diesel engines to up to 100,000 km on modern commercial diesel engines.
- Lubricating compositions for motor vehicles must therefore have improved properties and performance.
- Engine lubricating compositions must therefore fulfill many objectives that are sometimes contradictory. These objectives derive from the five main functions of engine lubricating compositions such as lubrication, cooling, sealing, corrosion protection and pressure transmission.
- Lubrication of the parts sliding on each other plays a decisive role, in particular to reduce friction and wear, including fuel savings.
- engine lubricating compositions Another essential requirement of engine lubricating compositions is related to the environmental aspects. It has indeed become essential to reduce oil consumption as well as fuel consumption, particularly in order to reduce C0 2 emissions. It is also important to reduce flue gas emissions, for example by formulating the oils so that the catalyst remains perfectly functional throughout its lifetime. It is also important to limit or avoid the use of toxic additives in order to reduce or limit their elimination, for example by reprocessing or combustion.
- gearbox or deck oils and more generally gear oils, must meet numerous requirements, particularly those related to driving comfort (perfect gearshift, quiet operation, trouble-free operation, high reliability ), to the service life of the assembly (reduction of wear during cold passage, no deposits and high thermal stability, safety of lubrication at high temperatures, stable viscosity situation and absence of shear loss, long service life) and consideration of environmental aspects (lower fuel consumption, reduced oil consumption, low noise, easy evacuation).
- ATF oils for automatic transmission fluids because of their use, it appears for the ATF oils very specific requirements which are a great constancy of the coefficient of friction. during the entire stay for optimal gear shifting, excellent aging stability for long emptying intervals, good viscosity-temperature performance to ensure perfect operation with a hot engine and a cold engine and compatibility sufficient sealing with different elastomers used in transmission joints to prevent them from swelling, shrinking or becoming brittle.
- vehicle transmission oils must also be supplemented with additives according to quality requirements, in particular high pressure additives.
- additives are also used.
- organometallic compounds for example comprising molybdenum and in particular molybdenum sulphide
- Molybdenum dithiocarbamates can be mentioned as the major source of molybdenum.
- various viscosity index improvers (co) polymers in a lubricant composition are also known.
- WO 2013-164449 discloses a PAG type oil derived from the copolymerization of butylene oxide and propylene oxide. This oil has a viscosity index of the order of 100 or 120.
- US 2014-018273 discloses methylated PAG oils having a high molecular weight or which include alkyl ether groups.

- the detergency of the lubricant compositions according to the invention is at the same level or better than that of the lubricant composition of the state of the art.
- the compatibility of the lubricant compositions according to the invention with the various elastomers that can be used in the transmission joints with which they are in contact is also at the same level or better than that of the lubricant composition of the state of the art.
- the lubricating compositions are prepared by mixing the oil (1) according to Example 1 and the known oils with other base oils according to the amounts (% by weight) of the Table 5.
- a comparative lubricating composition (3) is also prepared from a comparative oil (2) according to Comparative Example (3).
- the lubricating composition comprising the oil (1) according to the invention has improved properties.
- the kinematic viscosity measured at 100 ° C is lower.
- the dynamic viscosity (CCS at -35 ° C.) is lower, which puts forward an improvement in the cold behavior of the composition according to the invention.
- Example 8 Preparation of a Lubricating Composition According to the Invention, a Comparative Lubricating Composition and Evaluation of the Properties of these Compositions for the Lubrication of a Vehicle Engine
- the lubricating compositions are prepared by mixing the oil (1) according to Example 1 and known oils with other base oils and with additives for the preparation of lubricating compositions according to the quantities (% by weight) of Table 7 .
- Table 7 The characteristics of the lubricating compositions prepared are evaluated. The results obtained are shown in Table 8.
- Table 8 Compared to a lubricating composition comprising a group III oil, a group IV oil and the comparative oil (2) of the state of the art, the lubricating composition comprising the oil (1) according to the present invention. improved properties, and more particularly in "Fuel-Eco" gain.
- the viscosity index is higher. Dynamic viscosity (CCS at -35 ° C) is lower. Oxidation resistance is improved.
- Example 9 Preparation of a lubricant composition according to the invention, a comparative lubricating composition and evaluation of the properties of these compositions for lubricating the transmission of a motor vehicle
- the lubricating compositions are prepared by mixing the oil (2) according to Example 2 and the known oils with other base oils and with additives for the preparation of lubricating compositions according to the quantities (% by weight) of Table 9 .
- Composition Comparative composition (5) is prepared by mixing the oil (2) according to Example 2 and the known oils with other base oils and with additives for the preparation of lubricating compositions according to the quantities (% by weight) of Table 9 .
- additive mixture (dispersants
- the lubricating composition comprising the oil (2) according to the invention has improved properties.
- the viscosity index is much higher and the tensile coefficient is lowered by more than 12%. These parameters therefore make it possible to demonstrate the "fuel-eco" gain of the composition according to the invention.
