Description

The high-content that is used for alcohol engine lubricating oil is peace and quiet/dispersing additive
The invention provides the high-content that is applicable to ordinary internal combustion engine lubricating oil peace and quiet/disperse lubricating oil additive, thereby make lubricating oil can be used to burn alcohol or alcohol fuel, methyl alcohol for example, the oil engine of alcohol fuel.The present invention also provides the lubricating oil component that contains this lubricating oil additive, prepares the method for this lubricating oil component, and uses this emollient component to suppress engine corrosion and over worn method.
Because excessive engine wearing and tearing and lubrication oil consumption speed constantly increase, the lubricating oil that general engine uses is invalid in burning pure engine.One of reason is that the chemical reactivity of gasoline and the products of combustion of alcohol in engine fuel system has bigger difference.In pure fuel system, a large amount of lubricating oil generation DeRs, and this phenomenon can not occur in the Fuel Petroleum system.These chemical reactions cause increasing the corrosion of pure fuel system, and for example methyl alcohol is oxidized to formaldehyde and formic acid easily, and this reaction is represented with formula 1:
The vehicle of many use methanol fuels is because the formic acid that the methyl alcohol burning produces makes the piston Ministry of worker be subjected to excessive corrosion and bearing wear.Organic amine additive in formic acid and the engine oil commonly used reacts, and this additive plays antioxidant, the effect of corrosion inhibitor and anti-wear agent.In the amine additive and formic acid.Yet general additive it seems can not be fully in and the formic acid that generated of methyl alcohol burning.These reactions are represented with formula 2 formulas 3:
Easy and the amine additive reaction of formaldehyde.
Formaldehyde with as antioxygen, the reaction of the amine of antiacid and ashless dispersant.The formaldehyde reaction of formula 4 expressions is facilitated the degraded of oil in the methanol fuel system greatly.
Additive is owing to be consumed easily with formaldehyde and formic acid reaction, the lubricating oil additive that needs a kind of minimizing as far as possible and formaldehyde and formic acid reaction for the life-span that prolongs lubricating oil additive, equally, require lubricating oil additive can reduce the overreaction that oxidation of ethanol becomes acetaldehyde and Yi Suan And and reduces these components as far as possible as far as possible.
In pure fuel system, another major issue is a zinc dialkyl dithiophosphate, and it is a kind of main multifunction additive in most of all-purpose engine oils, and it easily transesterification takes place and loses its antiwear characteristics morely.Ester group reaction relates to the alkyl of alcohol, for example methyl alcohol or ethanol, and at ester, dialkyl group thiophosphoric acid zinc for example exchanges and generates new ester with former.React with formula 5 expression ester groups:
Transesterification is an acid catalyzed reaction, thus can occur in the aldehyde that produces in alkaline additive amine in lubricated and the combustion processes or Suan anti-Ying And depleted after.Transesterification is not the main course of oily DeR in the hydrocarbon fuel system, but transesterification is the main course of oil degraded in methyl alcohol and other fuel system.For example when methyl alcohol or ethanol and gasoline fusion, the amount of transesterification is proportional to the amount of alcohol in mixture.
Another factor that causes the corrosion aggravation in burning pure engine is that the solubleness of carbonic acid gas in alcohol becomes big.For example carbonic acid gas is dissolved in the methyl alcohol than water is easier.Water and methyl alcohol usually are to be present in part cold in the crankcase as products of combustion.Water and fuel combustion product, for example SO 3, NO 2And CO 2Reaction generates corresponding acid, sulfuric acid, and nitric acid and carbonic acid, with formula 6,7,8 expressions.
It is to cause oil engine corrosive one of the main reasons that acid is reacted with full genus in engine.The alkaline additive that is usually used in lubricating oil in the hydrocarbon fuel system, for example organic amine and alkali metal compound these acid that neutralized effectively.But because the solubleness of carbonic acid in alcohols is big, thereby the content ratio of carbonic acid is high in petrol system in methyl alcohol or other pure fuel system.From products of combustion NO 2The nitric acid that is generated also may be like this.The absorption of carbonic acid gas is the unexpected high major reason of pure fuel corrosion.
Lubricating oil analysis shows that the wear-resistant component that contains sulfonate, naphthenate or other alkaline metal salt generates insoluble alkaline carbonate precipitation owing to fallen by mass consumption with the carbonic acid reaction.Formula 9 and 10 expression precipitin reaction.
Compete with the reacting phase of carbonic acid in precipitin reaction and the organic amine.Though the faster and easier generation of neutralization reaction, the reaction of an alkali metal salt is consumed along with organic amine and accelerates.Therefore require not carry out too soon with the reaction of formic acid or acetate and carbonic acid in the organic amine in the lubricating oil additive, thereby be reduced in the possibility that alkaline metal salt is consumed in formula 9 and 10 precipitin reaction of representing.
General objective of the present invention provides a kind of lubricating oil additive be used to burn oil engine ， And of pure fuel and can protect because engine corrosion and the wearing and tearing that pure fuel causes.
