Abstract

835,158. Transducers. BRUCE PEEBLES & CO. Ltd., DUERDEN, F., NORMAN, G. P. F., and WATKINS, R. H. W. Sept. 30, 1958 [Oct. 1, 1957], No. 30719/57. Class 40(1). A transducer for' measuring the pressure variations inside the combustion chamber of an I.C. engine comprises an ignition plug, housing a piezoelectric element which is arranged to be subjected to the cylinder pressure. As shown (Fig. 1) a sparking plug transducer comprises a hollow steel body 11 and a central electrode 12 surrounded by an insulating sleeve 13 supported by a diaphragm 17 clamped to the body 11 along its outer circumference, and firmly attached to the central insulator 13 along its inner edge, thereby allowing small axial movements of the insulator 13. Located between a shoulder 25 of the insulator 13 and a screwed adjusting sleeve 23 are a cylindrical sleeve 26 of piezo-electric ceramic material and a washer 28, the sleeve 26 having silvered inner and outer faces which are connected by leads 29 to external voltage measuring apparatus. The E.M.F. output of the sleeve 26 is proportional to the internal cylinder pressure and may be shown on a cathode-ray oscilloscope. The interior of the body 11 may be water-cooled. In a second embodiment (Fig. 2, not shown) the diaphragm 17 is replaced by a resilient washer. The transducer may also be added to a glow plug for a compression-ignition engine.
