Strain gauge pressure sensor in IC engine cylinder head seal - provides metal enclosure for combustion chamber opening with strain gauge transducer for detecting combustion irregularities

摘要

The cylinder head seal has a metal enclosure (2) for combustion chamber openings (3) and sensors (5) on the seal for the detection of irregularities in the combustion process during engine operation. The sensor consists a strain gauge attached to at least one metal enclosure, and comprising an electrical resistance varied by extension and compression. ADVANTAGE - Effective, simple and reliable measurement device for detecting combustion irregularities.
