Patent ID: 7096725

Claim:
A multilayer metal gasket for an internal combustion engine, comprising: a first metal spacing layer having at least one opening for a combustion cylinder formed therein, said first spacing layer having a first sensor housing portion formed on a first surface thereof which opens into the combustion cylinder opening on one end and on an opposing end into a first channel portion which extends outwardly away from the first sensor housing portion; a second metal spacing layer separate from said first spacing layer; said second spacing layer having at least one opening for the combustion cylinder formed in a second surface thereof, said second spacing layer having a second sensor housing portion formed therein which opens into the combustion cylinder opening on one end and on an opposing end into a second channel portion which extends outwardly away from the second sensor housing portion; wherein the first sensor housing portion and the second sensor housing portion and the first channel portion and the second channel portion, respectively, are mating features and together form a sensor housing and a circumferentially enclosed signal line channel when the first surface and the second surface are placed in mating contact with one another; a sensor housed within the sensor housing; wherein said sensor is adapted to produce a sensor signal which is indicative of an environmental state within the combustion cylinder; a signal communication line located in the signal line channel, wherein said signal communication line is adapted to communicate the sensor signal from said sensor; and at least one metal sealing layer overlaying at least one of said first or second spacing layers and having at least one opening for the combustion cylinder formed therein and at least one outwardly facing sealing embossment overlaying said signal line channel in noninterfering relation with said signal communication line.
