Definitions
- the present invention relates to a lubricating oil composition favorably employable for lubricating internal combustion engines such as diesel engines and gasoline engines.
- the invention relates to a lubricating oil composition having a low sulfur content of about 0.5 wt.% or less, particularly about 0.2 wt.% or less, which reduces friction occurring in the internal combustion engines mounted to land-travelling automotives using low sulfur hydrocarbon fuel and shows good high temperature detergency.
- the sulfur contained in fuels such as gasolines or diesel fuels employed for operating internal combustion engines is oxidized when it bums in the engine to give sulfur oxide such as sulfuric acid.
- a portion of the sulfur oxide enter the lubricating oil employed for lubricating the engine, and the remaining portion is exhausted with other exhaust gases.
- the sulfur oxide exhausted with other exhaust gases causes environmental pollution.
- the sulfur content in the fuel has been heretofore under severe regulation.
- the regulation on the sulfur content was initially applied to gasolines (fuels for gasoline engines). However, the regulation on the sulfur content has been also applied recently to diesel fuels having a higher sulfur content.
- the sulfur content in the diesel fuels has been recently regulated to be not higher than 0.0010 wt.%.
- the lubricating oil is less contaminated with sulfur oxide such as sulfuric acid which is produced when the fuel bums. This means that the amount of the overbasic metal-containing detergent in the lubricating oil can be reduced.
- the basic metal-containing detergent serves for neutralizing the sulfur oxide in the lubricating oil.
- the recently employed lubricating oils for internal combustion engines comprise a base oil (hydrocarbon oil having lubricating viscosity) and a variety of additives (i.e., lubricating oil additives) such as a basic metal-containing detergent for neutralizing the emigrated sulfur oxide, an oxidation inhibitor for keeping the base oil functioning at elevated temperature from deteriorating, a dispersant for dispersing soots produced by burning of fuels and residues produced by deterioration of the base oil and metal-containing detergent in the base oil, an extreme pressure agent for preventing of seizure of the piston and cylinder, a friction-reducing agent (friction modifier) for reducing friction occurring between the piston and cylinder.
- a basic metal-containing detergent for neutralizing the emigrated sulfur oxide
- an oxidation inhibitor for keeping the base oil functioning at elevated temperature from deteriorating
- a dispersant for dispersing soots produced by burning of fuels and residues produced by deterioration of the base oil and metal-containing detergent in the
- the phosphorus component and metal component contained in the additive placed in the lubricating oil composition are decomposed when the lubricating oil composition bums and enter the exhaust gas in the form of phosphorus oxides and metal oxides.
- the phosphorus oxides and metal oxides contained in the exhaust gas are brought into contact with oxidative catalyst or reductive catalyst placed in the exhaust gas-cleaning apparatus and inactivate the catalyst.
- Patent publication 1 JP 2002-53888 A discloses a lubricating oil composition favorably employable for lubricating internal combustion engines operated using a fuel having a low sulfur content, particularly, diesel engines.
- the disclosed lubricating oil composition comprises a base oil having a sulfur content of 0.1 wt.% or less (preferably 0.03 wt.% or less) and the following additives:
- Patent Publication 1 further discloses in the working examples that the disclosed lubricating oil compositions show good high temperature detergency in the internal combustion engines.
- Patent Publication 1 furthermore discloses that the lubricating oil composition may contain a molybdenum-containing compound which can serve as a friction modifier, an oxidation inhibitor as well as an anti-wear agent.
- the molybdenum-containing compound can be one of known molybdenum-containing compounds such as sulfoxymolybdenum dithiocarbamate, sulfoxymolybdenum dithiophosphate and molybdenum complexes of succinimide possibly containing sulfur.
- Patent Publication 2 JP 2004-149802 A discloses a lubricating oil composition having a low sulfated ash content, a low phosphorus content and a low sulfur content, preferably employable for lubricating internal combustion engines (that is, engine oil), which comprises a base oil, an ethylene carbonate post-treated ashless dispersant, a borated ashless dispersant, an overbased metal-containing detergent and a phosphorus compound.
- Patent Publication 2 further discloses that the disclosed lubricating oil composition may contain a molybdenum-succinimide complex. In the working examples of Patent Publication 2, it is shown by experimental data that the lubricating oil composition shows good oxidation stability as well as good anti-wear performance.
- Patent Publication 3 discloses a low sulfated ash, low phosphorus, low sulfur engine oil (engine oil composition) comprising a low sulfur base oil, a boron-containing ashless dispersant, a molybdenum-containing friction modifier, a metal-containing detergent such as sulfonate, phenate or salicylate, and a zinc dithiophosphate.
- the molybdenum-containing friction modifier can be molybdenum diorgano-dithiocarbamate, molybdenum diorgano-dithiophosphate, molybdenum carboxylate, and a trinuclear molybdenum compound such as Mo 3 S 7 (dtc) 4 or Mo 3 S 4 (dtc) 4.
- the lubricating oil composition employing the above-mentioned trinuclear molybdenum compound has particularly good high temperature oxidation stability and a good friction reductive performance.
- the molybdenum-containing compound is particularly effective as a friction modifier to be incorporated into lubricating oil compositions.
- molybdenum diorgano dithiocarbamate and molybdenum diorgano dithiophosphate are most generally employed.
- both compounds have disadvantage problems, in that the former contains sulfur (S) in its molecular structure and the latter contains phosphorous (P) in its molecular structure, and hence both produce poisonous gases such as sulfur oxide gas and phosphorus oxide gas when the lubricating oil burns in the internal combustion engine, resulting in inactivation of the catalysts of the exhaust gas-clearing apparatus.
- Patent Publication 3 describes that a trinuclear molybdenum compound such as Mo 3 S 7 (dtc) 4 or Mo 3 S 4 (dtc) 4 shows a good friction-modifying function (friction-reducing function).
- these trinuclear molybdenum compounds contains sulfur atoms in the molecular structure of its ligand moiety, i.e., dithiocarbamate, dtc, and further contains other sulfur atoms directly attached to the molybdenum atom, and hence, the trinuclear molybdenum compounds contains a relatively large amount of sulfur in the compound per se. Therefore, the trinuclear molybdenum compound is not favorably employed for incorporation into the lubricating oil composition if reduction of the sulfur content in the oil composition is intended.
- Patent publication 4 ( US 2008/0234153 ) describes a lubricating oil composition
