(57) [Summary] [Purpose] A compression ratio that has deteriorated due to engine wear can be easily adjusted to a normal compression ratio without disassembly and repair. [Structure] An external threaded portion (3) is provided below a bolt-shaped hexagonal head (1), and an internal threaded portion (2) is provided inside the external threaded portion (3) to provide a tip portion. It is characterized in that (4) is projected into the cylinder head (6) to adjust the compression ratio.
Description
【考案の詳細な説明】 本考案は、エンジンの点火プラグに装着する点火プラグの補助具に関するも のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an auxiliary tool for a spark plug that is attached to a spark plug of an engine.
従来、オートバイ等の車のエンジンは、長年使用するとピストンリング等が 磨耗し、シリンダー内の体積が多くなり、圧縮比か低下して出力が下がり燃費 が悪くなる。 Conventionally, in the engine of a car such as a motorcycle, when used for many years, the piston ring and the like are worn, the volume in the cylinder increases, the compression ratio decreases, the output decreases, and the fuel efficiency deteriorates.
これを解消するには、エンジンの分解修理が必要であつた。 To resolve this, the engine had to be disassembled and repaired.
本考案は、その欠点を除くために考案されたもので、これを図面にて説明す ると、ボルト状を成す六角形の頭部（１）の下部に外ネジ部（３）を設け、外 ネジ部（３）の内部に内ネジ部（２）を貫通させて設ける。 The present invention was devised in order to eliminate the drawback, and it will be described with reference to the drawings. An external screw part (3) is provided at the bottom of a bolt-shaped hexagonal head (1), The inner threaded portion (2) is provided inside the outer threaded portion (3).
以上のように構成した点火プラグの補助具。 The auxiliary tool for the spark plug configured as described above.
これをエンジンのシリンダーヘット（６）に装着し、従来より一回り細い点火 プラグを取り付ける。 This is attached to the cylinder head (6) of the engine, and a spark plug that is slightly thinner than before is attached.
シリンダー内に突き出た本考案の先端部（４）の体積分だけ圧縮比が高くな り、分解修理の必要がなく簡単に正常な圧縮比に調整する事が出来る。 The compression ratio is increased by the volume of the tip (4) of the present invention protruding into the cylinder, and it is possible to easily adjust to a normal compression ratio without the need for disassembly and repair.
また、第２図は本考案の先端部（４）に切溝（５）を設け、燃焼効果を高め たものである。 Further, FIG. 2 shows that the cutting effect (5) is provided in the tip portion (4) of the present invention to enhance the combustion effect.
