Definitions

  • the present invention relates to a lubricant formulation, a method of lubricating and the use of a friction modifier additive.
  • the lubricant formulation, method and use may be employed in multiple application areas, specifically in engines.
  • the lubricant formulation and/or friction modifier additive may provide particular advantage in lubricating a vehicle in which the same lubricant formulation is used to lubricate the crankcase of an engine and a clutch.
  • a vehicle may be a two-wheeled vehicle, for example a motorcycle, preferably a motorcycle having a four-stroke piston engine.
  • the present invention relates to lubricant formulations for motorcycle engines where the lubricant formulation lubricates both a crankcase and a wet clutch and may be supplied from a common lubricant reservoir (or sump).
  • motorcycle lubricants may also lubricate other devices such as gears or bearings, each having their own lubricating requirement.
  • Many lubricant formulations have been designed over the years specifically for lubrication of motorcycles (also known as motorbikes or motorscooters). Because of the varied and demanding lubrication performance required of them, motorcycle lubricant formulations are designed specifically for use in motorcycles.
  • lubricant formulations used in lubricating passenger car engines are generally not suitable for motorcycles.
  • Lubricant formulations for passenger car engines may exhibit too low a coefficient of friction for lubricating the wet clutch found in most motorcycles.
  • the same lubricant reservoir (or "sump") supplies lubricant to the engine and clutch and may also supply the gears. Therefore the lubricant formulation must perform well in several, seemingly contradictory, environments:
  • crankcase the lubricant should reduce frictional losses to improve fuel
  • Fritch friction should be high at both low and high speed to ensure efficient torque transfer and quick clutch engagement respectively whilst minimizing wear and dissipating heat.
  • the Japanese Automotive Standards Organisation has introduced a standard (T903) which rates motorcycle engine oils based on their performance in the standard SAE no.2 test for clutch friction.
  • T903 standard classifies clutch friction performance into 3 ratings which are, in order of highest performance to lowest: MA2, MA1 and MB. If an oil has mixed MA2 and MA1 ratings, it is classified as MA.
  • MA rated motorcycle engine oils are Valvoline 4-Stroke Synthetic
  • the present invention is based in part on the recognition by the applicant that certain friction modifier additives can provide a surprising combination of a significant decrease in friction in a crankcase without a similar level of decrease of friction in a clutch.
  • a polyol selected from ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol polypropylene glycol, butylene glycol, propanediol, butanediol, glycerol and mixtures thereof;
  • the present invention provides a method of lubricating an internal combustion engine comprising a crankcase and a wet clutch, the method comprising supplying to the crankcase and the wet clutch a lubricant formulation comprising:
  • the lubricant formulation may be selected from a engine, gear, clutch or transmission lubricant formulation.
  • the lubricant formulation is an engine lubricant formulation, more preferably a piston engine lubricant formulation, particularly an automotive engine lubrication formulation, especially a motorcycle engine lubricant formulation.
  • the lubricant formulation may not be a metal-working fluid.
  • the lubricant formulation may not be a fuel.
  • the lubricant formulation may not be an emulsion, for example not a water in oil emulsion or an oil in water emulsion.
  • the lubricant formulation is non-aqueous.
  • components of the lubricant formulation may contain small amounts of residual water (moisture) which may therefore be present in the lubricant formulation.
  • the lubricant formulation may comprise less than 5 wt% water based on the total weight of the formulation, preferably less than 2 wt%, more preferably less than 1 wt%, particularly less that 0.5 wt%.
  • the lubricant formulation may be substantially anhydrous, preferably is anhydrous.
  • the lubricant formulation has an overall grade of MA, MA1 or MA2 as defined by JASO standard T903, more preferably T903:2016.
  • the lubricant formulation may comprise an additive pack suitable for its intended use, preferably a motorcycle oil additive pack.
  • an additive pack suitable for its intended use preferably a motorcycle oil additive pack.
  • the lubricant formulation may comprise no more than 40 wt% Group I base oil, preferably no more than 30 wt%, particularly no more than 20 wt%, desirably no more than 10 wt%, especially no more than 5 wt%.
  • the lubricant formulation may not comprise a Group I base oil.
  • the lubricant formulation may comprise at least 1 wt% Group I base oil.
  • the lubricant formulation may comprise no more than 85 wt% Group IV base oil, preferably no more than 70 wt%, particularly no more than 50 wt%.
  • the lubricant formulation may not comprise a Group IV base oil.
  • the lubricant formulation may comprise at least 1 wt%, preferably at least 5 wt%, particularly at least 10 wt% Group IV base oil.
