Abstract

PURPOSE:To prevent the damage of cylindrical electrode and elliptical conduction bodies and use them in internal combustion engine or the like for a long period by baking the overall surface of their inside after coating it with ceramics. CONSTITUTION:A cylindrical electrode body 3 with an air outlet port 1 forward and an air inlet port 2 backward is provided. A nearly elliptical conduction body 5 on the external surface of which a number of peak-shaped electrodes 4 are imbedded is retained inside the said electode body 3 by means of the front and rear support axes 6 and 6'. The air outlet port 2 is provided on an insulating plate 7 and the front support axis 6' is also made of an insulating material. The said cylindrical electrode 3 and elliptical conduction body 5 are connected to a high voltage generation transformer 8 with a constant voltage device through the support axis 6. As a result, the inner surface of the cylindrical electrode body 3 and the elliptical conduction body 5 generate a uniform spark, i.e. corona discharge between both electrodes through the peak-shaped electrodes 4 by the impression of the high voltage generation transformer. These, inside surface generating discharge are all baked and coated with ceramics.

Description

[Detailed Description of the Invention] Regarding the development of the electrode section, the purpose is to uniformly generate ideal plasma discharge in the positional relationship between the inside of the cylindrical electrode and the pointed electrode. The purpose is to measure the ionization performance of air and use it for internal combustion engines and other uses.

That is, to explain the drawing as an example, a cylindrical electrode body (3) having an air outlet (1) at the front and an air inlet (2) at the rear is provided, and inside the electrode body (3) A substantially elliptical current-carrying body (5) with many pointed electrodes (4) implanted on its circumferential surface is held by front and rear support shafts (6) (6)', and the air intake port (2) is insulated. The support shaft (6)' provided in the plate (7) and the front is also made of insulating material, and the cylindrical electrode (3) and the oval current carrying body (5) are connected to a high voltage having a constant voltage device through the support shaft (6). The inner surface of the cylindrical electrode body (3) and the oval current carrying body (5) are connected to the generating transformer (8), so that a uniform spark is generated between both electrodes by applying a high voltage generating transformer through the pointed electrode (4). That is, they generate corona discharge, and the inner surfaces of these discharge generating surfaces are all sintered and coated with ceramic coating.

As described above, the elliptical current-carrying body (5) in the cylindrical electrode body (3) has an elliptical shape with a large diameter in the center and a small diameter on both sides and an elliptic surface, which is the same as above. Pointed electrode (4
) are attached to the inner surface of the cylindrical electrode body (3), for example, in a staggered manner by screwing or other means, so that the apical electrode is located at the center of the inner surface of the cylindrical electrode body (3). It will get closer. This is a feature of the present invention, and the reason is that when the same high voltage is applied to all the pointed electrodes, the voltage applied to the pointed electrodes K located at both ends is electrically high, and corona discharge is easy to occur. 6, will it be difficult for the central electrode to discharge? Then, as described above, the two electrodes are brought close to each other, and an even discharge is generated by all the pointed electrodes and the inner surface of the cylindrical electrode body.

The electric field that is discharging the air that enters the air intake port ionizes the air, converting some of the oxygen into ozone, which is immediately decomposed into oxygen and oxygen atoms, which are then sent into the internal combustion engine through the outlet port, increasing combustion efficiency. It is possible to achieve the desired effect, such as by using it to improve one's abilities. Other uses are the same as before. Note that the elliptical electrode tl- in the cylindrical electrode
If the supporting shaft to be held is replaced with a rotating shaft and the elliptical electrode is rotated under high voltage application, the discharge effect will be even better.Moreover, all the electrode parts are covered with ceramic coating, so it is durable, and therefore, the discharge effect will be reduced. It can be used for a long time by preventing damage.
