[Problem that the invention seeks to solve]

In the oil regenerating device for an internal combustion engine as described above, since the filter (7) weighs about 30 g, for example, there is a problem that it is not possible to remove impurities such as dust of less than 30 g. In addition, in the internal combustion engine (1),
Because the plug ignites, carbon is generated in the engine oil, and this carbon is strongly electrostatically bonded to the oil molecules and cannot be removed by the filter (7), resulting in the problem of accelerated deterioration of the engine oil.

This invention was made to solve this problem, and is an oil regeneration device for an internal combustion engine that effectively removes impurities such as dust or carbon that are mixed or generated in engine oil and regenerates the engine oil. The purpose is to obtain.

[Means for solving problems]

The oil regeneration device for an internal combustion engine according to the present invention includes a voltage applying means for applying a voltage to engine oil, and a dust collecting means for collecting impurities in the engine oil.

[Effect]

In this invention, impurities such as dust and carbon that are electrostatically bonded to oil molecules are separated from the oil molecules by applying a voltage to the engine oil using a voltage applying means, and the separated impurities are bonded to each other. It becomes large particles and is removed by dust collection means.

〔Example〕

FIG. 1 is a side sectional view showing one embodiment of the oil regeneration device for an internal combustion engine according to the present invention, and in the figure (1) to Uυ are completely the same as the conventional device. In Figure 1,
4. (to) a pair of cylindrical electrodes serving as voltage applying means, to which, for example, the same pulse voltage as the pulse voltage applied to the spark plug of the internal combustion engine (1) is applied.

In the oil regeneration device for an internal combustion engine configured as described above, by applying a voltage between a pair of maw and The electrostatic bonds are broken, and the impurities such as dust and particles separated from the oil molecules are combined with each other to form large particles, which are removed by a filter (7) of about 80 μm, for example.

Therefore, even if impurities such as dust of about 1μ that could not be removed with conventional methods, these impurities combine with each other and reduce the amount to 80μ.
If it becomes more than that, it can be removed by filter (7),
Impurities such as dust can be removed with high precision. Also,
After combining impurities to make them larger, filter (7)
Large impurities are layered on the outer peripheral surface of the filter (7), and the engine oil passes through the gaps between the impurities; in other words, the large impurities themselves act as a filter. , filter (7
) clogging is significantly improved. Furthermore, carbon that is strongly electrostatically bonded to oil molecules can be separated from the oil molecules by applying voltage, making it possible to remove carbon that could not be removed in the past, preventing engine oil deterioration. and engine oil can be regenerated.

In addition, in the above embodiment, a pair of electrodes (6) are placed inside the container (5).
), q:1 was installed, but the electrode side was omitted and the container (5
) may be made of a conductor to serve as a ground electrode.

Further, in the above embodiment, the voltage applying means is connected to a pair of electrodes (2).
(13), and after breaking the electrostatic bond between the oil molecules of the engine oil and impurities, the engine oil was filtered with a filter (7), but the voltage application means was a pair of electrodes (b).
, a dielectric material may be installed between Cla,
For example, as shown in Fig. 2, a dielectric material αΦ made of an insulator such as glass or a semiconductor is installed between a pair of electrodes @ and □□□ to increase the electric field strength and reduce the electrostatic charge between oil molecules and impurities. Impurities whose electrostatic bonds with oil molecules have been broken may be electrostatically adsorbed onto the dielectric a< which is charged to a positive potential, while improving the bond-breaking property. Therefore, the time required to separate oil molecules and impurities is shortened, and the residence time of the acidic amount of engine oil between the pair of g and n poles can be shortened.

Furthermore, the dielectric material σ◆ may be made of a conductive material such as carbon or a semiconductor, and may be placed between a pair of electrodes n and a3 via an insulator (to) and a3 as shown in FIG. The length of the body 111 may be a mesh-like or porous body.

It has been experimentally confirmed that molecules charged with electric potential bond with each other, and if carbon is used as a dielectric material, carbon separated from oil molecules can be more effectively adsorbed. In this case, the dielectric σ4 may be a solid body, a mesh body, or a porous body coated with carbon.

Furthermore, in the above embodiment, the dust collecting means is a filter (7).
However, the dust collection means may also use an adsorbent or the like. For example, as shown in FIG. 4, for example, zeoherb,
Install an adsorbent qη such as activated clay, and connect a pair of electrodes (b).
, the engine oil whose electrostatic bonds between oil molecules and impurities have been broken in step a4 is forcibly passed through the adsorbent qη, the impurities are forcibly adsorbed at the adsorbent port, and then filtered with a filter (7). You may.

Furthermore, as shown in FIGS. 5 and 6, a dielectric material α is installed between the pair of electrodes (2),
2. An adsorbent αη may be installed between Q3 and the filter (7).

Furthermore, as shown in FIG. 7, a discharge port (2).

(801) each made of an insulating material, for example, 4#! (g), and an adsorbent ση may be placed between the pair of electrodes @ and a3.

In this case as well, impurities whose electrostatic bonds with oil molecules have been broken can be electrostatically adsorbed onto the adsorbent immediately.
The residence time between the pair of electrodes @ and □□□ of engine oil can be shortened.

Furthermore, as shown in FIGS. 8 and 9, by making the filter (7) multi-layered and installing it in order of coarseness,
Clogging of the filter (7) can be significantly improved.
