Description

  The present invention relates to a reforming method and a reforming apparatus for improving the lubricating performance of lubricating oil, and is suitable for application to engine oil.

Engine oil not only reduces the friction loss of the sliding part of the internal combustion engine, but also has an important role of protecting the engine by having a cooling action and a rust and corrosion prevention action.
The engine oil is vigorously stirred by rotation of the crank inside the oil pan and is in a state of being easily foamed.
The generation of bubbles accelerates the deterioration of the engine oil.If the air contained in the bubbles becomes a heat insulating material and the cooling effect is weakened, the oil temperature rises and promotes the oxidation of the engine oil. The oxidation of the engine oil makes it easy to take in moisture. Accelerating the deterioration of the engine oil in a chain, and having a problem of reducing the lubrication performance leads to an increase in fuel consumption of the engine.

  International Publication WO2003 / 044142 discloses a reforming method that lowers the viscosity by passing static electricity through the engine oil. However, in order to obtain the reforming effect, a long-time treatment is required and the processing equipment is dangerous. Is.

International Publication No. WO2003 / 044142

  An object of the present invention is to provide a reforming method and a reforming apparatus capable of extending the usable life of lubricating oil such as engine oil.

The engine oil reforming method according to the present invention includes a step of forming a flow path system for circulating engine oil, contacting the engine oil with infrared radiation ceramics in the middle of the flow path, and forming a magnetic field in the middle of the flow path. And a step of applying a line of magnetic force to the engine oil.
The present invention is suitable for engine oils but can also be applied to other lubricating oils.

  The engine oil reforming apparatus according to the present invention includes an engine oil storage unit, a circulation passage pipe that sucks the engine oil from the storage unit and returns the engine oil to the storage unit, and a circulation pump. Infrared radioactive ceramics that are in contact with the engine oil are arranged in one or both of the flow pipes, and a magnetic force generator that applies a magnetic field to the engine oil is provided in the middle of the flow pipe.

The engine oil that is the subject of the present invention is applicable to all engine oils used in various internal combustion engines.
Examples thereof include engine oil for gasoline engines and engine oil for diesel engines.
It is also possible to develop oil in general.

  The magnetic force generator used in the present invention is for forming a magnetic field in the middle of a circulation pipe and applying magnetic force lines to the circulating engine oil. The magnetic force is preferably 0.1 to 2 T (Tesla) level, which will be described later. A synergistic effect with the ceramics effect has been found to reduce the viscosity of the engine oil slightly and significantly extend the usable life.

As a ceramic used in the present invention, as a result of studying ceramics that emit a large amount of infrared rays, that is, using ceramics that emit a large amount of infrared rays in the vicinity of a wavelength of 6 to 8 μm based on the displacement law of Wien, such an effect is obtained. It has been found that there is.
As such ceramics, montmorillonite-based pyroxite-containing pyroxite, quartz porphyry and granite porphyry, kaolinite, and clay are pulverized and mixed, and fired into a predetermined shape to obtain porous ceramics. It was.
The mixing ratio is adjusted according to the required infrared radiation wavelength, but is generally: 0-20% by mass of quartzite, 10-30% by mass of quartz porphyry, 10-30% by mass of granite porphyry, 20% by kaolinite. ~ 40% by mass, magnetite: 10-15% by mass, clay: 20-40% by mass, and the mixture is about 360 mesh for wax stone, quartz porphyry, granite porphyry, and kaolinite It is good to grind into powder.
In addition, clay is good also as a remainder after mix | blending a predetermined ore using it for mixing | blending adjustment.
After mixing well with these mixers, etc., it was molded into a predetermined size and fired at 800-1000 ° C.
The reason why 10 to 15% by mass of magnetite is added here is that the effect of applying magnetic field lines is increased.

The engine oil reformed by the reforming method or the reforming apparatus according to the present invention has a service life of more than twice as long as engine oil not reformed.
In addition, since the lubrication performance is improved, it is possible to switch to a lower grade engine oil.
As a result, the oil change work is reduced and economical, and the waste oil is reduced, so it is environmentally friendly.
In addition, the engine sound is quieter, contributing to improved fuel efficiency.
Furthermore, the internal cleaning capability of the engine is improved, contributing to the reduction of harmful exhaust gases.

A configuration example of the engine oil reforming apparatus according to the present invention is schematically shown in FIG.
A circulation pump 5 is piped by a flow pipe 6 that forms a circulation flow path in a storage tank 1 that stores engine oil.
An in-tank ceramic cylinder 2 having a filter function is disposed in the storage tank 1, and a ceramic cylinder 3 and a magnetic force generator 4 are provided in the middle of the piping.

It is preferable to adjust the output of magnetic force and the blending and amount of ceramics when engine oil for gasoline engines is targeted and when engine oil for diesel engines is targeted.
As an example, the oil supply valve 8 is opened from an oil tank (not shown), and 50 L of diesel engine oil is introduced into the storage tank 1 using the circulation pump 5. , Granulated porphyry about 1.5, kaolinite about 2, magnetite about 1 and clay about 3 mass ratio, pulverized and mixed into a powder with an average particle size of about 360 mesh, about 15-30mm, almost spherical The resulting porous ceramic balls were baked at 800-1000 ° C., 1 kg each was put in the ceramic cylinder 2 and the ceramic cylinder 3 in the tank, the magnetic force was set to 0.7 T, and about 4 Time circulation processing.
The pipe diameter was 16A.
The take-out valve 7 was opened and the modified engine oil was taken out.

The results of comparative evaluation of viscosity, density and kinematic viscosity using the diesel engine oil thus modified and the diesel engine oil before the modification treatment as a comparative example are shown in the table of FIG.
The kinematic viscosity was calculated by measuring the viscosity and density.
The viscosity was measured at 40 ° C. using a B-type rotational viscometer manufactured by Tokyo Keiki Seisakusho.
The density was measured using a vibration type density meter DMA58 manufactured by Nippon Shibel Hegner.

In the table of FIG. 2, the comparative example is a value of diesel engine oil that has not undergone reforming treatment, and the running 0 km of the example is a value before use for running the engine with the modified engine oil.
Comparing this value, it can be seen that the viscosity is slightly lowered by the modification treatment.
Those not subjected to the modification treatment increased in kinematic viscosity to 143.7 cSt after running at 25,000 km.
In the case of diesel engine oil, if it exceeds the range of +25 to -40% relative to the initial kinematic viscosity (40 ° C), it is a guideline to change the engine oil. It will have to be replaced after traveling 25,000 km.
On the other hand, in the example, the kinematic viscosity tends to be lowered by running, and it can be seen that the range is still +25 to -40% even after running at 49000 km.
From this experiment, it was confirmed that the reforming treatment according to the present invention has the effect of extending the life of the engine oil.

  The modified engine oil had less foaming, so the progress of oxidation was suppressed, and it seems that it was possible to extend the service life.

1 shows the structure of a reforming apparatus according to the present invention. The change of the physical-property value of the engine oil which carried out the modification process which concerns on this invention is shown.
