Abstract
Description
この発明は、点火プラグの中心電極（１）と、接地電極（２）との間に絶縁された中間電極（３）を加えたことを特徴としたもので、点火プラグの火花の増加に関するものである。 The present invention is characterized by adding an insulated intermediate electrode (3) between a center electrode (1) of a spark plug and a ground electrode (2), and relates to an increase in sparks of the spark plug. It is.
従来の点火プラグは中心電極（１）と接地電極（２）で構成されていた。 Conventional spark plugs are composed of a center electrode (1) and a ground electrode (2).
これは次のような限界があった。点火プラグを使用する自動車等の内燃機関においては、エンジンの始動や、燃料消費率は点火プラグの発生する火花によっても左右されてきた。従って、点火プラグの各メーカーは、エンジン始動を容易にするためと、燃料消費量を少なくするために、従来では、点火プラグの火花を大きくするのに、点火プラグに高い電圧を掛けたり、中心電極（１）と接地電極（２）との間隙を大きくしたりして努力してきた。確かに間隙を大きくすることによって火花を大きくすることもできるが、現在では１，５％〜２，０％が間隙の限度であり、これ以上、間隙を広げると失火してしまい、かえって逆効果になってしまう。
そのために、火花の大きさも間隙によって左右されてきた。そこで各メーカーは従来の点火プラグに接地電極（２）を２本〜３本にしたり、また、１気筒内に２本の点火プラグを設けたりして、エンジンの始動を容易にすることや、燃料消費率の向上や、馬力の向上に努力してきた。
本発明は以上のような限界を超えるためになされたものである。This had the following limitations. In an internal combustion engine such as an automobile using a spark plug, the engine start and the fuel consumption rate have been affected by the spark generated by the spark plug. Therefore, in order to make the engine start easier and to reduce fuel consumption, spark plug manufacturers have conventionally applied a high voltage to the spark plug or increased the spark plug spark. Efforts have been made to increase the gap between the electrode (1) and the ground electrode (2). Certainly, the spark can be increased by increasing the gap, but at present, the limit of the gap is 1,5% to 20, 0%. Become.
For this reason, the size of the spark has also been affected by the gap. Therefore, each manufacturer has two or three ground electrodes (2) on a conventional spark plug, or two spark plugs in one cylinder to facilitate engine start, Efforts have been made to improve fuel consumption and horsepower.
The present invention has been made to exceed the above-described limitations.
本発明は、点火プラグの中心電極（１）と接地電極（２）の間を、従来の点火プラグの間隙を２倍にし、その間隙に絶縁された中間電極（３）を設けた点火プラグ。
本発明は、以上の構成よりなる中間電極（３）を設けた点火プラグ。The present invention provides a spark plug in which a gap between a conventional spark plug is doubled between a center electrode (1) and a ground electrode (2) of the spark plug and an insulated intermediate electrode (3) is provided in the gap.
The present invention is a spark plug provided with the intermediate electrode (3) having the above-described configuration.
点火プラグに中間電極を設けたため１本の点火プラグで２つの火花を飛ばすことができるため、エンジンの始動を容易にするとともに、燃料消費率の向上や馬力の向上にも寄与する。 Since the spark plug is provided with an intermediate electrode, it is possible to fly two sparks with a single spark plug, facilitating the start of the engine and contributing to an improvement in fuel consumption rate and horsepower.
以下、本発明を実施するための最良の形態について説明する。
従来の点火プラグの絶縁体（４）に中心電極（１）と漏電することの無い様に中間電極（３）を埋設し、中心電極（１）〜中間電極（３）と、接地電極（２）〜中間電極（３）の間隙に２つの火花を飛ばすことができる。
本発明は、以上のような構造である。Hereinafter, the best mode for carrying out the present invention will be described.
The intermediate electrode (3) is embedded in the insulator (4) of the conventional spark plug so as not to leak with the center electrode (1), the center electrode (1) to the intermediate electrode (3), and the ground electrode (2 ) To two sparks in the gap between the intermediate electrodes (3).
The present invention has the above structure.
