In order to reduce the wear of the cylinder liner, in addition to taking anti-corrosion and wear-resistant measures in design and manufacturing, the following points should be noted in the use and maintenance projects:

⑴ Correct starting and starting

After starting the cold engine, it should be warmed up for 3 to 5 minutes under a small throttle state before starting to drive. When running at the beginning, it should work at a small load for a period of time, and then work at a large load after the temperature rises.

⑵ Maintain the normal temperature of the engine

If the diesel engine temperature is too low, it cannot maintain good lubrication, which will increase the friction of the cylinder wall; if the temperature is too high, the cylinder strength will be reduced and the wear will be aggravated, and the piston may even expand excessively and cause a “cylinder pull” accident. The normal operating temperature of the diesel engine is 80℃~90℃. When it exceeds 95℃, the load should be reduced or the engine should be stopped for cooling.

⑶ Maintain good lubrication

Regularly check and maintain the good quality of the engine oil, the oil level is moderate, change it regularly, and select the engine oil with appropriate viscosity according to the season to ensure good lubrication.

⑷ Strengthen the maintenance of the “three filters” (air filter, oil filter and diesel filter)

This is the main measure to prevent mechanical impurities from entering the cylinder, reduce cylinder wall wear and extend the service life of the engine, which is especially important for loader diesel engines that are often in high dust content.

⑸ Improve maintenance and repair quality

Strictly perform maintenance and repair operations in accordance with the technical standards specified in the diesel engine maintenance manual. Adjust and control each matching clearance (opening clearance) to prevent accelerated wear between the piston and the cylinder wall due to improper repair and maintenance.
