Strain and Motion Measurement for Piston, Piston Ring and Connecting Rod of High Speed Running Engines using New Digital Telemeter 2008-01-1042

The authors have developed a measurement technique equipped with new digital telemeter for strain, motion and temperature of engine parts under high speed running operation with high accuracy. This telemeter has an original signal processing method in which the sensor outputs are directly converted to digital signals without conventional amplifiers and A/D converters. This telemeter enables multipoint measurements at high engine speed in small gasoline engines because of its compactness and lightweight. And this enables long hours of engine test without concern over battery life because of its low power consumption and self-contained power generation. We applied new developed digital telemeter to several measurements and analysis on the piston, piston ring and connecting rod.
