Definitions
- the present invention relates to the lubrication of hybrid motor vehicle engines and micro-hybrid powered vehicles, in particular micro-hybrid powered vehicles equipped with the "Stop-and-Start" system.
- Hybrid drive systems overcome these disadvantages by implementing an electric motor and a conventional thermal internal combustion engine, in series, in parallel or in combination.
- a hybrid vehicle starting is provided by the electric motor. Up to a speed of the order of 50 km / h, it is the electric motor that ensures the traction of the vehicle. As soon as a higher speed is reached or a strong acceleration is required, the internal combustion engine takes over. When the speed decreases or when the vehicle stops, the internal combustion engine stops and the electric motor takes over. Thus, the internal combustion engine of hybrid vehicles undergoes a significant number of stops and restarts compared to a conventional combustion engine thermal vehicles.
- certain vehicles are equipped with the "Stop-and-Start” system, also known as automatic stops and restarts. These vehicles are generally considered “micro-hybrid” vehicles. Indeed, these vehicles are equipped with a thermal internal combustion engine and an alternator-starter or a reinforced starter which ensure the stopping and restarting of the internal combustion engine thermal when the vehicle comes to a stop.
- the thermal internal combustion engines of microhybrid vehicles equipped with the "stop-and-start” system such as the internal combustion engines of hybrid vehicles, undergo a significant number of shutdowns and restarts compared to a thermal internal combustion engine. conventional vehicles.
- the internal combustion engine of hybrid vehicles or micro-hybrid vehicles undergoes, during its lifetime, a number of stops and start-ups much larger than that of a conventional vehicle.

- the Applicant Company has surprisingly found that the combination of these polyalkylene glycols and certain inorganic friction modifiers, in particular organomolybdenum compounds, advantageously makes it possible to further reduce the wear of the motor bearings.

- Hybrid motorized vehicles are here understood to mean vehicles using two different energy storages capable of moving said vehicles.
- hybrid vehicles combine a thermal internal combustion engine and an electric motor, said electric motor participating in the traction of the vehicle.
- the operating principle of hybrid vehicles is as follows:
- the kinetic energy is used to recharge the batteries.
- vehicle with micro-hybrid powertrain means vehicles comprising a thermal internal combustion engine, but no electric motor such as hybrid vehicles, the "hybrid” character being provided by the presence of the Stop and Start system provided by an alternator. -starter or a reinforced starter which ensure the stopping and restarting of the engine when the vehicle comes to rest and then restarts.
- the present invention more preferably relates to the lubrication of thermal internal combustion engines of vehicles equipped with hybrid or micro-hybrid systems circulating in an urban environment, where the Stop-and-Start phenomenon and the resulting wear are increased.
- a fixed part comprising the engine block, the cylinder head, the cylinder head gasket, the liner and various parts ensuring the assembly and sealing of these different parts.
- a movable part comprising the crankshaft, the connecting rod and its bearings, the piston and its segments.
- the role of the connecting rod is to transmit to the crankshaft the forces received by the piston, transforming a reciprocating rectilinear motion into a circular motion in one direction.
- a connecting rod has two circular bores, one of small diameter, called small end, and the other of large diameter called big end. Between these two bores, is the body of the connecting rod connecting the small end and the small end.
- the small end is engaged around the axis of the piston, the friction between the small end and the axis of the piston is reduced by the interposition between the two moving parts of a circular ring covered or made of anti-metal. friction (bronze, for example), or bearings (usually needle).
- crankpin crankpin The big end, it, encloses the crankpin crankpin.
- the friction between the crankpin and crankpin assembly is reduced by the existence of an oil film and the interposition between the crankpin and the crankpin, pads. In this case we speak of big-end bearings.
- crankshaft is a rotating part. Its positioning and maintenance are achieved by a number of bearings, called trunnions. So we have a fixed part, the bearing crankshaft, which encloses a moving part, the crankshaft journal. Lubrication between these two parts is imperative and pads are put in place to resist the forces applied to these bearings. In this case we speak of trunnion bushings (or bearings of shaft line or crankshaft bearings).
- the role of the bearing in the case of a big end or a trunnion, is to allow a good rotation of the crankshaft.
- the pads are thin shells in the shape of a half-cylinder. These are parts that are extremely sensitive to lubrication conditions. If there is contact between the bushing and the rotating shaft, crankpin or pin, the energy released systematically leads to significant wear or engine breakage. The generated wear can also play the role of amplifying the phenomenon and the severity of the contact.
- frequent stops and restart as is the case for vehicles with hybrid or micro-hybrid powertrain, the bearings are subject to frequent breaks and reboots of the oil film. Thus at each stop / restart takes place a contact between the metal interfaces and it is the frequency of occurrence of these contacts that is problematic for the pads.
- the bearings are subject to several types of wear in the motors.
- the different types of wear encountered in motors are: adhesive wear or wear through metal-to-metal contact, abrasive wear, corrosive wear, fatigue wear, or complex forms of wear ( contact corrosion, cavitation erosion, electrical wear).
- the pads are subject in particular to adhesive wear, the invention is particularly useful for improving this type of wear but the invention can nevertheless be applied to the other types of wear mentioned above.
- Surfaces that are sensitive to wear are metal-like surfaces, or metallic-type surfaces coated with another layer which may be either a polymer or an amorphous carbon layer. . Wear occurs at the interface between said surfaces that come into contact when the oil film becomes insufficient.
- the metal type surface may be a surface made of a pure metal such as tin (Sn) or lead (Pb). Most of the time, the metal type surface is a metal type alloy, based on a metal and at least one other metal element or not. A frequently used alloy is steel, iron alloy (Fe) and carbon (C).
- the bearings used in the automotive industry are mostly bearings whose support is made of steel, a support coated or not with another metal alloy.
- the other metal alloys constituting the metal surfaces according to the invention are alloys comprising as base element tin (Sn), lead (Pb), copper (Cu) or aluminum (Al).
- Cadmium (Cd), silver (Ag) or zinc (Zn) may also be basic elements of the metal alloys constituting the metal surfaces according to the invention.
- To these basic elements will be added other elements chosen from antimony (Sb), arsenic (As), chromium (Cr), indium (In), magnesium (Mg), nickel (Ni), platinum (Pt) or silicon (Si).
- Preferred alloys are based on the following combinations Al / Sn, Al / Sn / Cu, Cu / Sn, Cu / Al, Sn / Sb / Cu, Pb / Sb / Sn, Cu / Pb, PB / Sn / Cu, Al / Pb / Si, Pb / Sn, Pb / In, Al / Si, Al / Pb.
- the preferred combinations are Sn / Cu, Sn / Al, Pb / Cu or Pb / Al combinations.
- Copper and lead-based alloys are preferred alloys, and are also known as cupro-lead or white metal alloys.
- the surfaces affected by wear are polymeric surfaces. Most of the time, the pads are made of steel and additionally comprise this polymeric surface.
- the polymers that can be used are either thermoplastics such as polyamides, polyethylenes, fluoropolymers such as tetrafluoroethylenes, in particular polytetrafluoroethylenes (PTFE), or thermosets such as polyimides or phenoplasts (or phenol-formaldehyde PF resins).
- the surfaces concerned by the wear are surfaces of amorphous carbon type.
- the bearings are made of steel and include in addition this surface type amorphous carbon.
- the surfaces of amorphous carbon type are also called DLC, or Diamond Like Carbon or Diamond Like Coating, whose carbons are sp 2 and sp 3 hybridizations.
