Abstract:
1. A warning apparatus for signaling wear and tear of a timing belt in an engine, the engine mounted with a timing belt for interacting a rotation of a crank shaft with a rotation of a cam shaft, the apparatus comprising: magnetic force generating means each oppositely arranged about a timing belt to generate a mutually opposite polarity of a magnetic force; voltage inducing means disposed at one lateral surface of said timing belt to induce a voltage in response to the magnetic force generated from said magnetic force generating means; voltage detecting means for detecting the voltage induced by said voltage inducing means; a controller for outputting a control signal for generating a warning signal when the voltage detected by said voltage detecting means is less than an established level; and a warning generating unit for generating an alarm that a replacement time of a timing belt has arrived in response to the control signal from said controller.
