Definitions
- the present invention relates to a lubricating composition, in particular to a lubricating composition which is suitable for lubricating internal combustion engines and which has improved friction and wear
- Optimising lubricants through the use of high performance basestocks and novel additives represents a flexible solution to a growing challenge.
- Friction-reducing additives (which are also known as friction modifiers) are important lubricant components in reducing fuel consumption and various such additives are already known in the art .
- Friction modifiers can be conveniently divided into two categories, that is to say, metal-containing friction modifiers and ashless (organic) friction modifiers.
- Organo-molybdenum compounds are amongst the most common metal-containing friction modifiers. Typical organo-molybdenum compounds include molybdenum
- MoDTC molybdenum dithiophosphates
- MoDTP molybdenum dithiophosphates
- molybdenum amines molybdenum alcoholates
- molybdenum alcohol-amides molybdenum alcohol-amides .
- WO1998026030, WO1999031113, WO1999047629 and WO1999066013 describe tri-nuclear molybdenum compounds for use in lubricating oil
- Ashless (organic) friction modifiers which have been used in the past typically comprise esters of fatty acids and polyhydric alcohols, fatty acid amides, amines derived from fatty acids and organic dithiocarbamate or dithiophosphate compounds .
- lubricant additives which are used to reduce friction, do not typically also reduce wear.
- Typical additives for reducing wear contain both phosphorus and sulphur.
- phosphorus and/or sulphur containing additives can potentially poison catalysts in engine after-treatment systems, such additives are undesirable at higher levels.
- both a friction modifier and an anti-wear agent such as a phosphorus- or sulphur-containing anti-wear agent
- an anti-wear agent such as a phosphorus- or sulphur-containing anti-wear agent
- a friction modifier and an anti-wear agent typically needs to be added to the lubricant formulation.
- an anti-wear agent such as a phosphorus- or sulphur-containing anti-wear agent
- such a formulation may suffer from disadvantages such as poisoning of catalyst in engine after-treatment systems . Therefore it would be desirable to provide a lubricating composition which does not contain phosphorus- and sulphur-containing additives, or which contains low levels of such additives, but which still provides reduced friction and wear.
- the present invention provides the use of a lubricating composition
- a lubricating composition comprising (i) base oil and
- ashless friction modifier comprising Ci 2 -C 2 4 fatty acid and Ci 2 -C 2 4 fatty amine for providing reduced wear.
