  Conventionally, in general, an ignition device for a vehicle engine includes a distributor type in which a plurality of spark plugs are driven by a single ignition coil, and an independent ignition type in which a single ignition plug is driven by a single ignition coil. A power transistor is provided to drive the ignition coil.

  In addition, in order to improve engine combustion efficiency, lower fuel consumption, and lower exhaust gas, there have been cases where high-density negative ions are released into the air-fuel mixture and combustion exhaust gas of the engine.

  Furthermore, some of the ground wires attached to the distributor from the negative electrode (−) terminal of the battery for the purpose of improving engine performance are composed of hybrid wires made of complex wires having different frequency characteristics.

  As these conventional techniques, the prior arts of Patent Documents 1 to 3 shown below are known, and as a general technique for an ignition device for a vehicle engine, there is one disclosed in Patent Document 1 or the like. In the ignition device disclosed in Japanese Patent Laid-Open No. 5-106544 shown in Patent Document 1, the input signal from the microcomputer is switched and amplified by an igniter having a switching circuit for one circuit, and the switching amplified signal is increased in voltage by an ignition coil. And igniting the spark gap.

  Japanese Patent Application Laid-Open No. 2004-28072 disclosed in Japanese Patent Application Laid-Open No. 2004-28072 discloses a tapping piezoelectric member that rotates integrally with a crankshaft and that has tapping projections formed around the outer peripheral surface at predetermined intervals. The voltage ceramic module is contacted and struck by the struck convex part of the piezoelectric member to generate high pulse power, and the power transistor of the conversion circuit converts it to a high pulse on / off current signal and then turns it into the primary coil of the ignition coil The negative coil is output after the secondary coil outputs a negative high voltage DC pulse whose voltage is minus 3000V or more, the pulse number is 6 kilopulses or more, and the pulse number changes in proportion to the rotation speed of the crankshaft.

  However, in the method for generating negative ions for automobiles of Patent Document 2, it is necessary to replace parts such as a crankshaft and a piezoelectric ceramic module in order to attach to an existing vehicle. There were problems such as taking time and effort. Further, in the above-described earthing system and earthing method of Patent Document 3, even if a ground wire composed of complex wires formed of a plurality of thin wires or a hybrid cable composed of a plurality of complex wires having different frequency characteristics is used, Since each line is not insulated, it is the same as a single line, and there is a problem that the density of alternating current flow decreases due to the skin effect. Further, if the diameter of the conductor, that is, the electric wire is increased in order to prevent it, there is a problem that the weight and cost increase.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an electric wire and a method for connecting the electric wire, in which the engine performance of an automobile or motorcycle is simply improved.

  According to the present invention, according to the present invention, a plurality of electric wires insulated with a coating for each stranded wire are combined into one, further insulated with a coating, and the combined electric wire is arranged near the primary side of the ignition coil of the vehicle. The problem is solved by improving the high-frequency response by connecting between the batteries (−).

  According to the present invention, a plurality of electric wires insulated by a covering for each stranded wire are combined into one, further insulated by a covering, and the electric wire formed into a composite wire is connected to the vicinity of the primary side of the ignition coil of the vehicle and the battery (−). Since it is connected in between, when the primary side current of the ignition coil is interrupted or when a very high frequency AC current such as the edge of the pulse voltage generated by the spark current of the spark plug is passed, the same area as the single wire Even in such a case, the density at which the high-frequency alternating current flows can be increased, and the high-frequency response can be improved. In addition, the same current density can be ensured with a smaller diameter compared to a single wire, and the amount of conductive material used can be reduced, reducing the weight and cost. Furthermore, if high frequency response is improved by connecting a composite wire between the primary side of the ignition coil of the vehicle and the battery (-), the speed at the time of interruption increases and the energy loss of the spark plug spark current is reduced. Can be reduced. As the shut-off speed increases, the voltage rise in the initial stage of ignition becomes steep and a higher voltage is generated. As a result, high-frequency radio waves are emitted from the spark plug, and the air-fuel mixture in the engine cylinder is excited to cause ionization. When the air-fuel mixture is ionized, electric repulsion and suction occur, and the mixing method of gasoline molecules and oxygen molecules becomes uniform, and ideal combustion is obtained when a spark is blown into the homogenized air-fuel mixture. Together with this, it has become possible to provide a method for connecting a ground wire with improved combustion efficiency, lower fuel consumption, and lower exhaust gas for automobile and motorcycle engines.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, the present invention will be described in detail with reference to FIGS. In FIG. 1, (1) is a cross-sectional configuration diagram of an electric wire according to an embodiment of the present invention. (1-a) and (1-b) are insulation coatings, and (1-c) and (1-d) are combined. Is a stranded conductor, of which (1-c) is an effective cross-sectional area of current density, (1-d) is an ineffective cross-sectional area of current density, and in FIG. Since it can be regarded as the same as a single line when used, (1-c) and (1-d) are shown as single lines.
In FIG. 2, (2) is a cross-sectional view of a single wire having the same area as the wire (1) of FIG. 1, and (2-a) is an insulation jacket, and (2-b) and (2-c) are combined. A single wire conductor (2-c) is an effective cross-sectional area of current density, and (2-d) is an ineffective cross-sectional area of current density. FIG. 3 is a block diagram of a general independent ignition system for a four-cylinder vehicle, and FIG. 4 is a block diagram of an ignition device. An ignition signal is sent from the engine computer (10) to the ignition device (8). The sent ignition signal is amplified by the transistor (11) in the ignition device (8) and is increased in voltage by the ignition coil (12). The high-voltage energy is sent to the spark plug (9) and sparks, causing an explosion in the engine cylinder.

  The current flowing through a thick wire concentrates on the outer circumference of the conductor cross section as the frequency increases, and it has the property (skin effect) that does not flow beyond a certain depth depending on the frequency from the outer circumference of the conductor, and is equivalent to the one near the conductor center .

When calculating the current density of the conductor cross section for frequencies of 10 kHz, 100 kHz, 1 Mhz, and 10 MHz for a soft lead having a diameter of 1 mm, 98% of the outer periphery at 10 kHz, 41% at 100 kHz, 0.4% at 1 MHz, and 0.00000006% at 10 MHz. Become. For example, assuming that the current density for a certain frequency is 0.4 mm deep from the outer periphery, and the diameter of the single wire in FIG. 2 is 6.4 mm, the effective area of the current density of this single wire is (3.2 × 3.2 × π). − {(3.2−0.4) × (3.2−0.4) × π} ≈7.54 mm ²

When this is calculated with the electric wire composed of the composite wire of FIG. 1 having the same cross-sectional area as the single wire of FIG. 2, the area of the stranded wire conductor alone is the effective cross-sectional area of current density (1.21 × 1.21 × π) − {(1.21-0.4) × (1.21-0.4) × π} ≈2.54 mm ² , the effective cross-sectional area of the total current density of the seven wires is 17.78 mm ² , which is compared with a single wire Then, it becomes about 2.4 times. If the same current density as that of the composite wire is secured by a single wire, the diameter becomes 14.54 mm, and the wire diameter of the wire becomes unnecessarily thick.

  Further, when the weight is compared at a length of 1 m, the weight (4.56 cm 3 × 8.9 g / cm 3 × 7 = 286.) Of the electric wire (1) composed of the composite wire in FIG. 51 g. The weight of a single wire having an effective area of the same current density is 166.04 cm3 × 8.9 g / cm3 = 1477.78 g, which is five times as heavy.

Since the edge of the pulse voltage generated when the primary current of the ignition coil (12) is interrupted or the spark current of the spark plug (9) can be regarded as a very high frequency, a plurality of wires insulated with a coating for each stranded wire By combining the wires together and further insulating them with a coating, the density of alternating current can be increased even in the same area as that of a single wire, and the wire formed as a composite wire can be used as the primary side of the ignition coil (12) of the vehicle. By connecting between the vicinity and the battery (−), if the high frequency response is enhanced, the speed at the time of interruption is increased and the energy loss of the spark current of the spark plug (9) can be reduced. By increasing the shut-off speed, the voltage rise at the initial stage of ignition becomes steep and a higher voltage is generated. As a result, high-frequency radio waves are emitted from the spark plug (9), and the mixture in the engine cylinder is excited to cause ionization. When the air-fuel mixture is ionized, electric repulsion and suction occur, and the mixing of gasoline molecules and oxygen molecules becomes uniform, and ideal combustion is obtained when sparks are blown into the homogenized air-fuel mixture. By combining a plurality of wires insulated with clothes for each one and further insulating with a coating, and using a wire made of composite wire, the same current density can be secured with a narrow diameter compared to a single wire, and the conductive material The amount used can be reduced and the weight and cost can be reduced.

  3 and 4, the ground of the ignition device (8) is common with the ground of the spark plug (9), but the emitter of the transistor (8) in the ignition device (8) is connected to a separate line depending on the vehicle. Needless to say, the wire of the present invention may be connected between the connected place and the battery (−).

It is sectional drawing of the electric wire of this invention. It is sectional drawing of a single line. It is a block diagram of a general independent ignition device. FIG. 3 is a detailed view of the ignition device of FIG. 2.
