Electrical connections for a piezoelectric pressure transmitter for an internal combustion engine

摘要

A cylinder pressure transmitter has means mounting piezoelectric means to provide an electrical signal corresponding to the pressure of a cylinder of an internal combustion engine and has electronic means on the mounting means to amplify the signal for transmission to computer control means for regulating engine operation to improve performance. The electronic means are mounted on an insulating substrate which is secured to a rigid support in a housing. Contact means, guide means, and locating means provided on the housing and on the mounting means cooperate to mount the housing on the mounting means to provide reliable interconnection between the electronic and piezoelectric means and to retain the interconnection even when subjected to engine vibrations.
