Definitions
- the present invention is applicable to the field of lubricants, more particularly to the field of engine lubricants. More particularly, the present invention relates to the use of a lubricating composition for decreasing rattling in a vehicle engine, said lubricating composition comprising at least one base oil and at least one organic anti-rattling compound.
- the lubricant composition according to the invention thus makes it possible to reduce or even eliminate rattling in an engine of vehicles, preferably motor vehicles, while retaining good lubricating properties.
- the present invention also relates to a lubrication process using this composition.
- the present invention also relates to a method for reducing or even suppressing rattling in an engine of vehicles, preferably motor vehicles, implementing this lubricant composition.
- the present invention also relates to the use of an organic compound in a lubricant composition for reducing or even suppressing rattling in an engine of vehicles, preferably motor vehicles.
- the present invention also relates to the use of a concentrated composition of additives comprising at least one organic compound for reducing or even suppressing rattling in an engine of vehicles, preferably motor vehicles, using said organic compound.
- Knocking is a phenomenon that occurs in a spark ignition engine of vehicles, and more particularly in a spark ignition engine of motor vehicles and is due to the self-ignition of the fuel upstream of the flame front in the chamber of combustion.
- This auto-ignition propagates at a very high speed in the combustion chamber and causes vibrations at high frequencies of the gaseous mass and thermal overload of the engine, which can lead to serious mechanical incidents.
- the combustion phenomenon is a compromise between the propagation speed of the flame front from the spark plug and the self-ignition time of the fuel. When the latter is too short, the rattling occurs in the remote areas of the spark plug and most often near the piston and the cylinder.
- a lubricant and more particularly a motor lubricant, is used in the cylinders to reduce friction and wear.
- the proximity of the engine lubricant to the zones of occurrence of rattling opens the possibility of interaction between it and combustion.
- WO2004 / 101717 describes the use of organometallic compounds based on manganese in a lubricant composition to reduce the phenomenon of rattling in an engine.
- organometallic compounds promotes deposits in the combustion chamber and can thus cause abnormal combustion such as hot-spot ignition which can cause significant mechanical failure. In addition, they may pose a risk to human health.
- WO2004 / 104717 also describes various organic compounds of alcohol, ester or ether type that can be used in a lubricant composition to reduce the knocking phenomenon in an engine.
- US 8129320 discloses oils selected from trimellitic acid esters or alkyl naphthalene type compounds, and their use in a lubricant composition to reduce the phenomenon of rattling in an engine.
- the content by weight of these oils in the lubricant is at least 50% which can greatly reduce the friction reduction or oxidation resistance performance of the lubricant composition.
- An object of the present invention is therefore to provide organic compounds and a lubricating composition comprising these organic compounds which overcome all or part of the aforementioned drawbacks.
- Another object of the present invention is to provide a composition for reducing or even suppressing rattling in an engine and whose formulation is easy to implement.
- Another objective of the present invention is to provide a lubricant composition that makes it possible to reduce or even eliminate rattling in an engine while avoiding the appearance of deposits in the combustion chamber.
- Another object of the present invention is to provide a lubrication method for reducing or even suppressing the rattling in an engine.
- the invention thus relates to the use of a lubricant composition for reducing rattling in an engine of vehicles, preferably motor vehicles, said lubricant composition comprising:
- R1 represents a hydrogen atom, a linear or branched, saturated or unsaturated, substituted or unsubstituted alkyl group comprising from 1 to 10 carbon atoms, a group -OR17, a group -NR18R19;
- R2 represents a hydrogen atom, a linear or branched, saturated or unsaturated, substituted or unsubstituted alkyl group comprising from 1 to 10 carbon atoms, a group -OR20, a group -NR21 R22;
- R3 represents a hydrogen atom, a saturated or unsaturated, substituted or unsubstituted, linear or branched alkyl group comprising from 1 to 10 carbon atoms, a group -OR23, a group -NR24R25;
- R4 represents a hydrogen atom, a linear or branched, saturated or unsaturated, substituted or unsubstituted alkyl group comprising from 1 to 10 carbon atoms, a group -OR26, a group -NR27R28;
- R5 represents a hydrogen atom, a linear or branched, saturated or unsaturated, substituted or unsubstituted alkyl group comprising from 1 to 10 carbon atoms, a group -OR29, a group -NR30R31;
- R6 represents a hydrogen atom, a linear or branched, saturated or unsaturated, substituted or unsubstituted alkyl group comprising from 1 to 10 carbon atoms, a group -OR32, a group -NR33R34
- R7 represents a hydrogen atom, a linear or branched, saturated or unsaturated, substituted or unsubstituted alkyl group comprising from 1 to 10 carbon atoms, a group -OR35, a group -NR36R37
- R8 represents a hydrogen atom, a linear or branched, saturated or unsaturated, substituted or unsubstituted alkyl group comprising from 1 to 10 carbon atoms, a group -OR38, a group -NR39R40
- R9 represents a hydrogen atom, a linear or branched, saturated or unsaturated, substituted or unsubstituted alkyl group comprising from 1 to 10 carbon atoms, a group -OR41,
