Abstract:
A combustion pressure sensor assembly comprising:a structure having a first end and a second end, said first end inserted into a screw hole formed in an engine, said structure having a screw portion that screw connects said structure to an inside peripheral surface of said screw hole, said structure having a nut portion on the second end for providing rotational force around an axis of said structure to screw connect the first end of said structure to said inside peripheral surface of said screw hole; a combustion pressure sensor having a through hole through which the structure is inserted for detecting combustion pressure of the engine; and a lead wire that carries an outputted signal from the combustion pressure sensor to an external receiving area; wherein the combustion pressure sensor is attached to the structure by inserting the structure into the through hole of the combustion pressure sensor to attach the combustion pressure sensor to the structure; and wherein the second end of the structure including the nut portion is smaller than an inside diameter of the through hole of the combustion pressure sensor, the structure being inserted into the through hole of the combustion pressure sensor from the second end of the structure.
