Reference Answer
### **1. Objective of Cylinder Liner Calibration**
The primary objective of calibrating a cylinder liner is to accurately quantify the internal wear that has occurred over a period of operation. This data is critical for:
* **Monitoring Wear Rates:** To establish a trend and predict the remaining service life of the liner.
* **Detecting Abnormal Wear Patterns:** To identify conditions such as ovality, barrelling, or clover-leafing, which can indicate underlying issues like misalignment, improper lubrication, or thermal stress.
