Definitions
- the internal combustion engines to be treated include gasoline engines, diesel engines, propane engines, rotary engines used in general cars, buses, trucks and motor bicycles which must be subjected to regular automobile inspection and registration and, furthermore, engines for agricultural equipments, engines for construction vehicles, engines for ships, industrial engines (for compressors, generators and airconditioners) and engines for aircrafts.
- strain friction in engines (internal combustion engines) for cars including imported cars and motor bicycles causes incomplete combustion due to delicate deviation (a lag in timing of ignition and valve operation) in interlocking operation process of mechanism leading to intake, compression, combustion and exhaustion (valve system, rotating parts, sliding parts) which must be kept regular.
- the inventors have conducted intensive research in an attempt to find a method for improving performance of internal combustion engines by completely cleaning and discharging carbon, sludges and the like deposited and accumulated inside internal combustion engines, especially adhering oxidation waste matters and simultaneously by coating and mending the surface of metallic parts such as rotating parts and sliding parts having roughness and flaws such as friction marks, wear marks and hairlines without employing a method which requires labor and time for disassembling, cleaning of the parts and assembling.
- the present invention has been accomplished.
- the present invention provides a method for cleaning and discharging (removing) the adhering oxidation waste matters in internal combustion engines without disassembling the engine into parts and simultaneously coating (mending of coat) the roughened surface by friction reaction.
- the present invention provides a cleaning and coating composition used for the method of cleaning and coating without disassembling the internal combustion engines into the parts.
- composition for cleaning and coating of inside of internal combustion engines is mainly composed of a zinc phosphate, a solvent, a surface active agent, a mineral oil and a natural vegetable oil.
- the first aspect of the present invention relates to a composition for cleaning and coating of the inside of internal combustion engines which is mainly composed of a zinc phosphate, a solvent, a surface active agent, a mineral oil and a natural vegetable oil.
- the second aspect relates to a composition for cleaning and coating of the inside of internal combustion engines which contains 0.35-3.5% by weight of a zinc phosphate, 25-45% by weight of a solvent, 3.5-18% by weight of a surface active agent, 6-12% by weight of a mineral oil and 1.6-12% by weight of a natural vegetable oil, the total amount of the zinc phosphate, the solvent, the surface active agent, the mineral oil, the natural vegetable oil and water being 100% by weight.
- the zinc phosphate means not only zinc phosphate tetrahydrate, but also zinc dialkyldithiophosphates, zinc diaryldithiophosphates, mixtures of dialkyldithiophosphate esters and zinc oxide and mixtures of alkyl alcohols or aryl alcohols, phosphorus pentasulfide (P 2 S 5 ) and zinc oxide.
- compositions containing a zinc phosphate which are commercially available in the name of "Zinc" as an engine oil supplying agent are also included.
- Amount of the zinc phosphates in the composition is 0.35-3.5% by weight. If the amount is less than 0.35% by weight, the coating effect is insufficient and if it is more than 3.5% by weight, no greater improvement in coating effect can be obtained.
- the zinc dithiophosphates are dispersed in a mineral oil, followed by mixing and dispersing with other components. That is, when zinc phosphate tetrahydrate is used, it is dissolved in a small amount of water (usually water containing a small amount of an acid or alkali being used) and then mixed and dispersed with a mineral oil so that it is contained in an amount of 0.35-3.5% by weight in the composition.
- mineral oils can be used, but bright stock (or bottom) oils (virgin oils of high concentration) are suitably used.
- Amount of the mineral oil in the total composition can be optionally selected from the range of 6-12% by weight based on the total weight of the composition.
- the solvents used in the present invention are petroleum solvents such as, for example, aromatic solvents, aliphatic solvents or mixtures thereof.
- solvents must be selected taking into consideration the conditions that they exert no evil influence (bad effect) upon other engine parts (packing such as gasket and sealing parts) and that they are low in dangerousness such as explosiveness and flammability.
- Amount of the solvents is 25-45% by weight based on the total amount of the composition. If the amount is less than 25% by weight, the effect to remove oxidation waste matters is not sufficient and if it is more than 45% by weight, there may occur problems in combustibility and hence use of them in an amount of up to 45% by weight is preferred.
- the surface active agents there may be used anionic, nonionic, amphoteric and cationic surface active agents. These may be used each alone or as a mixture.
- the first object to use the surface active agents is to emulsify and disperse each component of the composition.
- the second object is to exhibit the action as an aid for acceleration of liberation and dissolution of oxidation waste matters such as carbon and sludges by penetration and activation power (activation action) and the third object is to disperse (emulsify) combustible compositions such as petroleum solvent and natural vegetable oil in water, thereby to neutralize into moderate effect with no evils and besides to neutralize and solve the dangers such as flammability.
- anionic, nonionic, amphoteric and cationic surface active agents may be used, but suitable are nonionic alkylphenylpolyoxyethylene ether surface active agents and polyethylene glycol fatty acid ester surface active agents.
- Amount of the surface active agents is 3.5-18% by weight based on the total amount of the composition and this is sufficient. If the amount is less than 3.5% by weight, the effect to emulsify and disperse all the components is insufficient and if it is more than 18% by weight, the problem of bubbling occurs and no further improvement of detergency can be expected.
- the natural vegetable oils are used for effective coalescent mixing of the components and acceleration of dissolution and removal of especially the sticking oxidation waste matters such as carbon and sludges adhering to and accumulated in the inside of engines and for exhibiting masking effect for offensive smell of the composition.
- the natural vegetable oils include terpineol, d-limonene, eugenol and l-carvone. Amount of the natural vegetable oils is 1.6-12% by weight based on the total composition.
- the amount is less than 1.6% by weight, the masking effect is insufficient and 12% by weight is enough to exhibit the masking effect and the masking effect no longer increases even when more than this amount is employed. Thus, 12% by weight suffices.
- composition of the present invention is made up to 100 parts by weight in total by adding water to a blend of the above components. Usually, amounts of other components are selected so that amount of water is 28-55% by weight based on the total composition. Of course, water can be added to the blend of the above components at the time of use.
- each component may be selected so that lubricity can be obtained as a property.
- the cleaning and coating composition can be prepared by mixing the components and stirring the mixture, and the mixing method and the stirring method are not limiting.
- the cleaning and coating method of the present invention can be applied to any internal combustion engines regardless of the kind. That is, it can be applied to various internal combustion engines for cars, buses, trucks, motor bicycles, construction vehicles, agricultural equipments, ships, aircrafts, airconditioners, generators and compressors, such as, for example, gasoline engines, diesel engines, LPG engines, rotary engines and others.
- the composition is used for cleaning and coating in an amount of 80-120% based on the amount of engine oil used.
- the engine is started and idled for a given time, for example, about 1-5 minutes to circulate the composition through the whole engine.
- the engine is stopped and left to stand for 10-30 minutes after stopping, and again idled.
- the idling is effected for at least 10-30 minutes and the engine is again stopped.
- the drain cock is opened and all of the cleaning composition used for cleaning is drawn out.
- a "Zinc" product (zinc thiophosphate ⁇ zinc dithiophosphate) which comprised an oil previously containing the zinc phosphate in an amount of 1.25% by weight in the total composition and a mineral oil in an amount of 5.75% by weight, the total amount of the zinc phosphate and the mineral oil in the total composition being 7% by weight, was added to a mixture comprising 26 parts by weight of naphthenic paraffin petroleum solvent: Nippon Oil N-22, 6 parts by weight of d-limonene as a natural vegetable oil, and 8 parts by weight of a nonionic surface active agent: nonylphenol EO adduct and 5 parts by weight of an imidazolium betaine amphoteric surface active agent as surface active agents, and these were thoroughly stirred. After stirring, water was added to make up 100 parts by weight in total, followed by further stirring to obtain a cleaning and coating composition.
- a cleaning and coating composition was obtained in the same manner as in Example 1, except that 5 parts by weight of a cationic surface active agent: monoalkylammonium chloride was used in place of 5 parts by weight of the imidazolium betaine amphoteric surface active agent.
- the cleaning and coating agent drawn out changed to deep brown in its color, which showed that it removed carbon and sludges inside the engine, and furthermore, the cleaning and coating agent which was in "smooth state” and free-flowing before use changed to "thick state”.
- the cleaning and coating composition of the present invention is considered to have markedly excellent cleaning action, and moreover, regarding the improvement of the output, it must be concluded that function of the engine per se was recovered considering the covered distance of the car used.
- Example 4 The same procedure as in Example 4 was repeated using a Nissan Pulsar 1700 cc diesel of November, 1992 type (model: X-SN14, motor CD-17) of 9982 km in the distance covered.
