Bimetallic cylinder liner is a special engine component used to protect the engine cylinder block, made of two layers of metal with different coefficients of expansion. When using, the following points should be noted:

1. Installation accuracy: Ensure that the cylinder liner is installed in place to avoid stress concentration or deformation caused by improper installation.

2. Temperature control: The bimetallic cylinder liner is sensitive to temperature, and overheating should be avoided during operation to prevent uneven expansion of the inner and outer metal layers, which may cause cracks or detachment.

3. Lubrication maintenance: Regularly check and replace lubricating oil to maintain good lubrication and prevent wear from worsening.

4. Material monitoring: After long-term use, it is necessary to check whether there are cracks or wear on the surface of the cylinder liner, and replace the severely worn parts in a timely manner.

5. Suitable operating conditions: According to the engine design requirements, select the appropriate working load and speed to avoid exceeding the design limits.

6. Avoid corrosion: To prevent coolant leakage or acid erosion, regularly clean the surface of the cylinder liner.

Following the above points can effectively extend the service life of bimetallic cylinder liners and ensure the normal operation of the engine.
