摘要：
The present invention is an apparatus and a method for monitoring a sliding state of a piston ring. The present invention detects a cycle of rotation of a piston ring based on a temperature at a predetermined site of a cylinder liner, and determines a sign of burning of a piston based on a state of the rotation. As a result, it is possible to detect a sign of burning of a piston by an apparatus less expensive than apparatuses using a conventional technique of detecting a capacitance.
