Abstract
A sensing assembly identifies detonations in a plurality of cylinders of an internal combustion engine. The internal combustion engine includes an engine block. The sensing assembly includes a base that is fixedly secured to the engine block of the internal combustion engine. The sensing assembly also includes a sleeve that is fixedly secured to the base and extends outwardly therefrom. A sensor element extends around a portion of the sleeve. The sensor element receives vibrations generated by the detonations of the internal combustion engine and converts those vibrations into an electrical current. The sensing assembly includes a first terminal abutting the sensor element. The first terminal includes a first terminal pad directed in a first direction. The sensing assembly also includes a second terminal abutting the sensor element. The second terminal includes a second terminal pad directed in a second direction opposite the first direction such that leads connected to each of the first and second terminal pads are prevented from shorting the sensor element.
