DEVICE FOR DETECTING THE COMBUSTION CHAMBER PRESSURE IN AN INTERNAL COMBUSTION ENGINE

摘要

A combustion chamber pressure sensor (11) in an engine accessory component (10) is proposed, said combustion chamber pressure sensor (11) comprising a sensor carrier (14) which is accommodated in a housing (12). Moreover, a pressure sensor element (21) which comprises a membrane (22) is provided at an end of the sensor carrier (14) proximal to the combustion chamber. The pressure sensor element (21) is in the form of an eddy current sensor (32) which comprises at least a first electromagnetic coil (34).
