<P>PROBLEM TO BE SOLVED: To provide a pressure measuring plug with bandwidth improved and built-in height reduced. <P>SOLUTION: This piezoresistive pressure measuring plug includes the plug body to be inserted into cylinder of internal combustion engine, a rod arranged inside the plug body, and a sensitive structure containing piezoresistive element. The sensitive structure is installed in between the rod and the plug body to be activated by the pressure, circulating around internal combustion chamber of the cylinder in use. The rod transmits the pressure in the internal combustion chamber of the cylinder to the sensitive structure. <P>COPYRIGHT: (C)2010,JPO&INPIT |
