Tracking of Piston Movement Using Large Mirrors for Piston drive Analysis

Abstract

In our study, a piston movement was tracked by controlling the gaze direction of the two mirrors in order to observe the piston that moves at high speed during driving of the engine. Since the piston motion is considered to be a sine curve, a mirror control signal of a sine curve was created using the function generator. In this experiment, the gaze direction of the mirrors was controlled according to the trigger signal from the engine under the condition that the engine speed was known. As a result, we confirmed that the piston movement could be tracked with some degree of accuracy.
