内燃機関の圧力検出装置。 In a pressure detection device for an internal combustion engine, a ring-shaped pressure sensor is sandwiched between the mounting surface of an ignition plug that is screwed into a cylinder head, and the cylinder internal pressure is measured by the output of the pressure sensor. A protection tube made of a rigid member is placed over the outer periphery of the output signal extraction lead wire pulled out from a part, one end of the protection tube is fixed to the lead wire extraction part of the pressure sensor, and the other end is used to ignite the cylinder head. A pressure detection device for an internal combustion engine, characterized in that the device is positioned so as to protrude from the upper end opening surface of a plug insertion hole.
