註釋This book deals systematically with the creation of piezoelectric knock sensors for automotive engine control. The authors consider the problems encountered in the theoretical modeling and design of primary piezoelectric acceleration gauges for various objects and classify specific features of automotive internal combustion engine detonation as well as basic types of knock sensors and their design concepts. The advantages and disadvantages of the following piezoelectric sensors are analyzed: compression-type, bend-type, shear-type, and resonance- and semiresonance-type transducers. The authors describe techniques based on the calculation of electroelastic sensing elements for different kinds of deformations, such as compression-expansion, bending, and shear, and analyze forced oscillations of transducers with one or several degrees of freedom.
