Definitions
- a lubricant for use in internal-combustion engines having ferrous metal cylinders which lubricant comprises a lubricating oil having dispersed therein one or more substances of a class which counteracts the catalytic action of the ferrous metal upon the oil.
- This class of materials includes organic compounds of chromium and organic compounds of tin. Other suitable organo-metallic compounds may readily be determined by carrying out oxidation tests on the oil in the presence of iron.
- a feature of this invention therefore consists in dispersing in the lubricating oil, in addition to an anticatalyst, a small proportion of a substance for counteracting the aforesaid direct oxidation.
- Various substances are already known to possess this property, such as tin compounds; thus, according to this invention there may be dispersed in the oil'bpth a small proportion of an organic compound of chromium and a small proportion of an organic compound of tin. It is indicated above that tin is included in the class of material which counteracts the catalytic action of the ferrous metal upon the oil. It, however,
- Another cause of deterioration of the lubricating oil is due to spontaneous ignition or cracking'of the oil under high temperature and pressure conditions.
- the lubricating oil has dispersed therein both a small proportion of a substance for counteracting the aforesaid action of metallic surfaces on the oil, for example a small proportion of chromium or its compounds, and a small proportion of a sludge-preventing substance, such as tin or its compounds, and a small proportion of a substance for raising the temperature at which spontaneous ignition or cracking of the 011 takes place, for example tetra-ethyl lead or other suitable lead compounds.
- a substance for counteracting the aforesaid action of metallic surfaces on the oil for example a small proportion of chromium or its compounds
- a sludge-preventing substance such as tin or its compounds
- a substance for raising the temperature at which spontaneous ignition or cracking of the 011 takes place for example tetra-ethyl lead or other suitable lead compounds.
- the invention includes within its scope a lubricant comprising a lubricating oil having dispersed therein in addition to a small proportion of an organic compound of chromium either a small proportion of an organic compound of tin, or of an organic compound of lead, or both said latter substances.
- oil-soluble compounds of the above metals are selected, such as chromium oleate, tin oleate and tetra-ethyl lead, which substances may be added to the oil in proportions of up to 1% by weight of each compound, according to the nature of the lubricating oil treated.
- chromium oleate such as chromium oleate, tin oleate and tetra-ethyl lead
- chromium oleate such as chromium oleate, tin oleate and tetra-ethyl lead
- a lubricant comprising a lubricating oil 5 ing oil having dispersed therein material having dispersed therein in material amounts 5 amounts up to .4% chromium oleate, up to up to .4% chromium oleate and up to .1% tin .1% tin oleate and up to .1% tetra-ethyl lead. oleate.
