How to reduce the wear of cylinder liners

How to reduce the wear of cylinder liners

2019-05-25 14:20

Cylinder liners are divided into two categories: dry liners and wet liners. The cylinder liner whose back side does not contact the cooling water is called a dry cylinder liner, and the cylinder liner whose back side is in contact with the cooling water is a wet cylinder liner. Cylinder liner is the abbreviation of cylinder liner, which is embedded in the cylinder of the cylinder block and forms a combustion chamber together with the piston and the cylinder head. If the cylinder liner is used frequently, it will inevitably cause abrasion. So how can the wear of the cylinder liner be reduced? The following editor will introduce to you.

1. Starting and starting: When starting for the first time, the engine of the cylinder liner should be idled for a few revolutions, and the friction surface should be lubricated before starting. Otherwise, when the engine of the cylinder liner is cold, the temperature is low, the oil viscosity is high, and the fluidity is poor, which makes the oil pump insufficient. At the same time, the oil on the original cylinder wall flows down the cylinder wall after stopping, so it cannot get as good lubrication as it does during normal operation at the moment of starting, which greatly increases the wear of the cylinder wall during starting.

2. strengthen the maintenance of the filter: some drivers do not install the air filter in order to save fuel is more correct and wrong. Keeping the air filter, oil filter and fuel filter in good working condition is essential to reduce the wear of the cylinder liner.

3. Maintain the normal working temperature of the engine of the cylinder liner: The normal working temperature of the engine should be at 80 to 90 degrees Celsius. The temperature is too low to maintain good lubrication, which will increase the wear of the cylinder wall. The water vapor in the cylinder is easy to condense into water droplets, dissolving the acid gas molecules in the exhaust gas, generating acidic substances, and causing the cylinder wall to be corroded and worn.

The above are some precautions for reducing cylinder liner wear. I hope it can help everyone. If you have any questions or needs about the cylinder liner, please feel free to contact us or leave a message on our website!
