SENSOR FOR DETERMINING THE COMBUSTION PROFILE IN AN INTERNAL COMBUSTION ENGINE

摘要

In a sensor for determining physical processes in the combustion chamber of an internal combustion engine, the measurement electrode is arranged separately from the metallic screw-in part (10). The measurement electrode consists of a wire (17) or a mesh-like sheath (22) sintered into the spark plug insulator (12) and is earthed by means of a measurement element (19). The ignition can be monitored and at the same time the quality of the firing of the mixture can be assessed by measuring the ignition current.
