Abstract

This paper presents an approach to measuring axial piston ring movement in a running combustion engine using a wireless telemetry system. The electrical design of the telemetry is discussed as well as steps taken to enable operation under the extreme conditions inside an engine. Emphasis is placed on the embedded system, power supply, signal acquisition, and data post-processing techniques. The paper concludes with an outlook for future applications and measurements with eddy current sensors.
