Definitions
- Lubricating composition having improved emulsion stability
- the present invention relates to the lubrication of a vehicle comprising at least one combustion engine.
- the present invention relates to the lubrication of a hybrid vehicle engine of the plug-in hybrid vehicle type and a hybrid vehicle comprising a range extender.
- Hybrid vehicles include two engines, a combustion engine and an electric motor.
- the thermal engine drives the wheels and is assisted by an electric motor.
- a battery provides the electricity necessary for the operation of the electric motor, this battery is, in the case of conventional hybrid vehicles, recharged during the braking and deceleration phases, by a kinetic energy recovery system (SREC) integrated into the vehicle.
- SREC kinetic energy recovery system
- hybrid vehicle technologies There are different hybrid vehicle technologies. Among these hybrid technologies, we can notably cite:
- micro-hybrid vehicles also called mild hybridization
- these vehicles equipped with the “stop&start” system, recover the energy generated by braking to charge a battery which can momentarily assist the thermal engine;
- - full-hybrid vehicles are vehicles with total hybridization.
- the electric motor takes care of starting and locomotion.
- the heat engine takes over, when increased power is needed (for example acceleration) the two engines work together. It is thus possible to drive with the combustion engine off for a few kilometers.
- plug-in hybrid vehicles and hybrid vehicles including a range extender Other complementary technologies have recently been developed: plug-in hybrid vehicles and hybrid vehicles including a range extender.
- Rechargeable hybrid vehicles also called plug-in in English
- the battery can be recharged on the electrical network, these vehicles can thus drive in 100% electric mode over a distance of several tens of kilometers , for example 50 kilometers.
- hybrid vehicles including a range extender also called range extender
- only the electric motor drives the wheels. This electric motor is powered by a battery for a few dozen kilometers.
- the thermal engine starts and drives a current generator making it possible to produce the electricity necessary to recharge the battery and maintain the operation of the electric motor.
- Lubricating compositions and in particular those used for the lubrication of combustion engines, generally comprise small quantities of water resulting in particular from the direct adsorption by the lubricant of water contained in the air or even from the condensation of the ambient water vapor.
- a lubricating composition thus typically comprises 0 to 10% water.
- water in lubricating compositions is the cause of cold starting problems, corrosion but also premature wear of the combustion engine. In order to prevent these phenomena, it is then necessary to maintain this water in the form of an emulsion.
- the thermal engine is used less often, which has the effect in particular of promoting problems of demixing of the lubricating composition.
- the lubricating composition remaining stationary, the emulsion becomes unstable, the water separates from the oily phase and forms a continuous phase.
- An objective of the present invention is to provide a lubricating composition allowing the lubrication of an internal combustion engine, in particular a plug-in hybrid vehicle engine or one comprising a range extender.
- Another objective of the present application is to provide a lubricating composition having improved emulsion stability.
