ガスの削減につながる効果がある。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spark plug cord used for an internal combustion engine. 2. Description of the Related Art As shown in FIG. 2, a conventional spark plug cord for an internal combustion engine has a plug cap 2 provided with a spark plug fitting 1 and a disputer fitting 9.
And a cord body 7 having a carbon, Kevlar or variable pitch core 10
It is a configuration connected by. [0003] The carbon, Kevlar or variable pitch core wire 10 has a higher resistance value for reducing noise, and has a function which is contrary to the power transmission performance originally intended by the plug cord. Since the carbon, Kevlar, or variable pitch core wire 10 has a predetermined resistance value for reducing noise, efficient ignition spark cannot be strengthened. That is, since the ignition noise (noise radio wave) is reduced by increasing the resistance value of the carbon, Kevlar or variable pitch core wire 10, the power transmission performance decreases in inverse proportion to the magnitude of the resistance value. That is, the ignition spark is also weakened in inverse proportion. From the viewpoint of the above prior art, it is possible to increase the ignition spark by reducing the resistance value as much as possible, however, it is necessary to reduce the resistance value below a predetermined value. Then, radio interference occurs from the ignition system and the like, and ignition noise enters the engine control computer and the audio. Noise must not cause abnormalities in computer control. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a plug cord having a strong ignition spark without generating noise and without changing the voltage enhancing device of the spark plug cord for an internal combustion engine. SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, an object of the present invention is to increase ignition spark while minimizing ignition noise during fuel ignition. An object of the present invention is to develop a spark plug cord for an internal combustion engine characterized in that the ignition spark is strengthened without changing the voltage enhancing device of the spark plug cord for the internal combustion engine and without adding another power source. More specifically, the present invention is to increase the resistance of the spark plug connection fitting 1 of the plug cord of the conventional configuration in order to increase the ignition spark while minimizing ignition noise during fuel ignition. 3. An internal combustion engine characterized in that the ignition spark is strengthened by taking out the insulation coating 4 and covering the resistance-carrying conducting wire 3 from above the insulation coating 4 with a shield wire 5 and grounding it at a terminal 6. It is a spark plug cord for use. With this configuration, it is possible to increase the ignition spark while minimizing ignition noise at the time of fuel ignition. An embodiment of an ignition plug cord for an internal combustion engine according to the present invention will be described with reference to FIG. The spark plug cord for an internal combustion engine includes a plug cap 2 provided with a spark plug connection fitting 1 and an end cap 8 provided with a disputer connection fitting 9, and a carbon or Kevlar or variable pitch core wire 10 having a predetermined resistance value. The resistance-equipped conducting wire 3 is connected to the ignition plug mounting bracket 1 by a predetermined length and is covered with an insulating coating 4. The shielded wire 5 is surrounded by the shielded wire 5 from above the insulating coating 4 and the shielded wire 5 is grounded by the terminal 6. As seen from the conventional spark plug cord for an internal combustion engine shown in FIG. 2, "the insulation wire 4 is covered on the current-carrying wire 3 with resistance," which is connected to the spark plug connection fitting 1, and the shield wire 5 is further placed thereon. Cover, and a terminal 6 for grounding the shield wire 5 is attached to one end. " [0011] The structure of this additional portion to be united is
This is one of the features of the present invention. "The insulation wire 4 is put on the current-carrying wire 3 with resistance, and the shield wire 5
, And a terminal 6 for grounding the shield wire 5 is attached to one end of the cable. " The spark plug cord for an internal combustion engine according to this embodiment is constructed without adding a power source such as a battery for enhancing the voltage from the outside. [0013] The present invention has devised a configuration for enhancing the spark simply by connecting a cord having a predetermined configuration. That is, the length of the current-carrying wire 3 with resistance or
By changing the resistance value, the intensity of the ignition spark can be changed. Therefore, the size of the spark for each cylinder of the engine can be adjusted only by adjusting the current-carrying wire 3 with resistance, the spark can be uniformly adjusted, and proper engine operation can be performed. To explain the noise control in the embodiment of the present invention, as in the conventional device, the carbon, Kevlar or variable pitch core wire 10 having a predetermined resistance value has a function of reducing noise generation. On the other hand, the configuration in which the shielded wire 5 is covered from the insulating coating of the resistance-containing conducting wire 3 covered with the insulating coating 4 and the shield wire 5 is grounded at one end does not block noise. In the spark plug cord for an internal combustion engine according to the embodiment shown in FIG. 1, a plug cap 2 provided with a spark plug connection fitting 1 and an end cap 8 provided with a distributor connection fitting 9 are made of carbon, Kevlar or variable pitch. It is connected by a cord body 7 having a core wire 10 and the resistance value of the carbon or Kevlar or variable pitch core wire 10 is increased to reduce noise as much as possible. The set conducting wire 3 with a resistance is taken out and covered with an insulating coating 4. The conducting wire 3 with a resistance is surrounded at its end by an insulating coating 4.
And the shield wire 5 is grounded at the terminal 6 so that the voltage can be concentrated and strengthened by the current-carrying wire 3 having a resistance completely different from that of the plug cord 7, so that ignition noise at the time of fuel ignition is minimized. Sparks can be strengthened. [0017] Aside from a cord body 7 having a carbon or Kevlar or variable pitch core 10, a resistance-containing conducting wire 3, an insulating coating 4, a shielded wire 5, and a grounding terminal 6, which can be set to a predetermined length and resistance value, are provided. Provided. It is possible to increase the combustion spark of an engine of an automobile or the like without generating useless noise, thereby improving the combustion efficiency. Other Embodiments In the embodiment shown in FIG. 1, the ignition spark is strengthened by the action of the current-carrying wire 3 with resistance, the insulating coating 4, the shield wire 5, and the terminal 6, and the current-carrying wire 3 with resistance is ignited. It is connected to the plug connection fitting 1. As another embodiment, it is possible to propose a form in which the resistance-containing conducting wire 3 is connected in the middle of the carbon, Kevlar or variable pitch core wire 10. Due to the structure of the plug cord, there is a case where the energizing wire with resistance may be output from the middle. As described above, in the spark plug cord for an internal combustion engine according to the present invention, an ignition spark is generated by the function of the current-carrying wire 3 with resistance, the insulating coating 4, the shield wire 5, and the terminal 6 for grounding. As described above, the ignition spark can be increased without adding another power source or changing the voltage enhancing device. Therefore, there is an effect that the combustion efficiency of the engine is improved and the exhaust gas is reduced.
