METHOD AND APPARATUS FOR MEASURING TIMING OF CRANK SHAFT AND CAM SHAFT OF ENGINE

摘要

The present invention relates to a crankshaft and a camshaft timing measuring apparatus and method of an engine, comprising: a reflective tape attached to a pulley of a shaft to measure rotational state, and a laser beam installed at a position spaced apart from the shaft or the reflective tape; A torsional vibration meta which can measure the rotational state of the shaft with the laser beam reflected from the reflective tape while scanning, storage means for storing a signal from the torsional vibration meta, and from the torsional vibration meta or storage means The oscilloscope's calculation function analyzes data on the rotational status of the crankshaft and camshaft using a device composed of an oscilloscope that can compute and visually present the signal of the crankshaft and cam. Shaft rudder It may obtain information about Ming.
