Cylinder head seal for internal combustion engine - has combustion pressure measurement detector consisting of pressure-sensitive resistance located between crossing conductive tracks in seal to detect combustion irregularities

摘要

The seal has at least one measurement device (5) mounted on it for indirect detection of the combustion chamber press. of the combustion engine, esp. for detecting irregularities in he combustion process. The measurement device consists of two mutually overlapping and/ or crossing electrical conductors (7,8), between which , in the overlap and/or crossing regions (6), an electrically resistive material (9) is arranged. Under press. the resistance of the material varies with press. and controls the current flow between the conducting tracks accordingly. USE/ADVANTAGE - For detecting combustion irregularities in combustion engine. Measurement system can be mounted in cylinder head seal simply and without adversely affecting sealing.
