構造。The cylinder head of a spark-ignition internal combustion engine has a part for installing the spark plug, and the lower end of the part has a female thread that communicates with the combustion chamber, and the spark plug is attached to the female thread. In this case, the mounting part has a regulating hole in its deep part, and the regulating hole has a diameter slightly larger than the outer diameter of a plug wrench for inserting the spark plug, and a depth that is greater than the screw reach of the plug. The structure of the spark plug installation in an internal combustion engine is characterized by a large circular hole.
