Abstract
A cylinder liner for an internal combustion engine is formed of cylindrical liner body having an interior cavity with a cylindrical inner surface, a sensor embedded in the cylindrical liner body and being configured for sensing a physical condition on the cylindrical inner surface, and a transmitter connected to the cylindrical liner body at a position remote from the sensor. A connecting wire connects the transmitter to the sensor, and is embedded in in the cylindrical liner body. The sensor is located in an upper portion of the cylindrical liner body and the transmitter is located directly below the sensor, such that the wire runs vertically. The transmitter can send information obtained by the sensor to a remote processor for calculating various operating states of the liner.
