Definitions

  • This invention relates to lubricants and particularly to lubricants based on vegetable oils that are intended for use in two-stroke engines.
  • Automotive lubricating oils have hitherto been largely based on mineral oils. Despite the wide availability of vegetable oils and the apparent attractions of using such renewable and environmentally-friendly source materials, the use of vegetable oils as lubricant base fluids has been highly restricted. They have not found wide applicability in high-performance modern lubricants. Rape seed oil and castor oil, for example, have been and are used in lubricants in specific applications.
  • Two-stroke engines have for many years now enjoyed considerable success, for example, as motor cycle engines, outboard motors and chainsaw engines. This is due in no small part to their high output per unit weight and their relative simplicity and versatility, for example, their having no sump.
  • the invention provides a satisfactory, high performance lubricant for two-stroke engines, which is based on palm oil.
  • the invention provides a lubricating oil for a two-stroke engine which comprises palm olein as base fluid and one or more dispersants in an amount of from 1 to 10% by weight.
  • a lubricating oil for a two-stroke engine which comprises palm olein as base fluid and one or more dispersants in an amount of from 1 to 10% by weight.
  • the lubricating oil comprises the following constituents by weight:
  • the invention provides the use as a lubricating oil for a two-stroke engine, of a palm olein- based formulation as detailed in the immediately-preceding paragraph.
  • the palm olein is present in an amount of from 40 to 90% by weight.
  • any balance of the formulation may be made up using other base fluids, preferably synthetic or mineral oils, i.e. refined petroleum fractions.
  • Suitable synthetic base fluids include, for example, poly alpha olefins and synthetic esters, e.g. polyol or dibasic acid esters.
  • Other base fluids derived from vegetable oil sources may also be incorporated in the formulation.
  • any other desired additives may be included, e.g. a metal passivator, to reduce the tendency of metals to catalyse oxidation of the oil, may be used in up to 0.5% by weight.
  • Suitable passivators are well known in the field of lubrication.
  • Other additives which may be included dependent on the intended use and environment of use include thickeners and pour point depressants.
  • An ester additive to retard crystallisation of the palm olein is preferably included in an amount up to about 0.24% by weight, preferably from 0.04 to 0.18%.
  • the ester additive is an ester of sorbitan and stearic acid.
  • it may be sorbitan monostearate, sorbitan tristearate or poly-oxyethylene sorbitan tristearate, sorbitan tristearate being particularly preferred.
  • it may be, for example, a polyglycerol ester.
  • Palm olein is a liquid fraction derivative obtained when the palm oil is fractionated into solid and liquid fractions. It typically has Iodine Values (IV) in the range from about 55 to 67. Iodine Value is an indication of the degree of unsaturation of the oil, the higher the value the greater the unsaturation. See Institute of Petroleum method IP84 for a detailed explanation of its measurement. Palm olein has been widely used, particularly in the Far East and South America, as a food/edible oil, particularly for frying.
  • the actual temperature and form of crystallisation depends on a number of factors including the IV of the olein used, the rate of cooling and whether the test method is isothermal or temperature programmed. For example, if test methods are equal, a specific palm olein of relatively high IV might start to become cloudy due to crystallisation at, say, 15°C, whereas one of lower IV, e.g. 55, might start at 20°C. Similarly, two identical oleins may crystallise at different temperatures if subjected to different temperature regimes.
  • the stabilised palm olein should have an IV of at least 60 and preferably from 62 to 67. Palm oleins of lower IV have been found to be less preferable, albeit still usable, in that, even when stabilised, they are likely to undergo crystallisation causing cloudiness during normal temperature changes in a tropical climate.
  • two-stroke lubricating oils of the present invention can be formulated to have particularly useful application in relatively hot climates where minimum temperatures are unlikely normally to fall below about 12°C. Thus, for example, they may be of particular value in tropical regions of countries such as Brazil, Malaysia, Singapore, Indonesia and Thailand.
  • the anti-oxidant may be, for example, an amine, phenol or phosphite-based additive, well known per se in the lubricant art, and is preferably present in an amount of from 0.5 to 1.5% by weight.
  • the smoke suppressant may be, for example, polyisobutene and may be used in sufficiently large amounts to be considered also as an additional synthetic base fluid.
  • the dispersants, detergent and corrosion inhibitors may be any conventionally used in the lubricant art and are preferably present in amounts of from 4 to 9%, 1 to 3% and 0.5 to 1.5% by weight respectively.
  • Suitable dispersants are alkyl (mono and bis) succinimides of a range of molecular weights, or a Mannich type base.
  • Suitable detergents are neutral and/or overbased calcium, magnesium, sodium or barium sulphonates or phenates.
  • Suitable corrosion inhibitors are metal phenates, basic metal sulphonates, fatty acids and amines.
  • the diluent may be, for example, a petroleum distillate with a flash point above 60°C which helps the oil to mix satisfactorily with the fuel prior to ignition in the engine.
