ABSTRACT:
A combustion chamber pressure sensor for an internal combustion engine includes an elongated pressure transmitting member having one end exposed to the interior of an engine cylinder and the opposite end contacting a pressure sensing element which generates a pressure measurement signal, the pressure transmitting member and pressure sensing element being contained within an elongated housing. A damping body formed of a viscoelastic material is disposed on an outer or inner circumferential surface of the housing, for reducing an amount of engine vibration that is transmitted to the pressure sensing element and thereby reducing noise in the pressure measurement signal.
