Abstract
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. Guide means and locating means provided on the housing and on the mounting means cooperate in mounting the housing on the mounting means and contact means on the piezoelectric and electronic means fit together in an improved manner to provide reliable interconnection between the electronic and piezoelectric means and to retain that interconnection even when subjected to engine vibrations.
