With the continuous progress of our scientific research, the performance of zirconia ceramic cylinder liners is also constantly improving, and the application scope is also expanding.

Zirconia ceramic cylinder liner is an abbreviation for zirconia ceramic cylinder liner, which is embedded in the cylinder body of the cylinder block and forms the combustion chamber together with the piston and cylinder head. Zirconia ceramic cylinder liners can be divided into two types: dry zirconia ceramic cylinder liners and wet zirconia ceramic cylinder liners.

The zirconia ceramic cylinder liner that does not come into contact with the back cooling water is a dry zirconia ceramic cylinder liner, while the zirconia ceramic cylinder liner that comes into contact with the back cooling water is a wet zirconia ceramic cylinder liner. Zirconia ceramic cylinder liner has a simple structure, thin thickness, and easier processing. Zirconia ceramic cylinder liners come into direct contact with cooling water, which is beneficial for engine cooling, miniaturization, and lightweighting.

The main processing flow of zirconia ceramic cylinder liner is cylinder barrel: cutting rough turning heat treatment (quenching and tempering) turning (flat chamfering) inner hole rough pushing inner hole rolling turning (cylindrical opening) inner hole stopper. I believe that with the continuous advancement of our technology, the performance of zirconia ceramic cylinder liners will be continuously improved, and their applications will become more widespread.

Now we all know that newly purchased cars must be well maintained in order to extend their lifespan. The same applies to zirconia ceramic cylinder liners, which must be well maintained. What should be done specifically? Let's take a closer look:

Under normal driving conditions, the brake shoes should be checked every 5000 kilometers, not only to check the remaining thickness, but also to check the wear status of the brake shoes, whether the degree of wear on both sides is the same, and whether they can recover freely. Any abnormal situation must be dealt with immediately.

2. Brake shoes are generally composed of iron lining plates and friction materials. They must be replaced in a timely manner and should not be replaced before severe polishing. Some vehicles are equipped with brake shoe warning function. Once the wear limit is reached, the instrument will sound an alarm, prompting to change shoes. Shoes that have reached their usage limit must be replaced. Even if it can still be used for a period of time, the braking effect will decrease, affecting driving safety.

When replacing, the brake pads provided by the original factory accessories should be replaced. Only in this way can the braking effect between the brake pads and brake discs be optimal with minimal wear.

When replacing the brake shoes, tools must be used to push back the brake cylinder. Do not use other pry bars to press back, as this can easily cause the lead screw of the brake caliper to bend, resulting in the brake pads getting stuck.

After replacing the brake shoes, it is necessary to break in for 200km to achieve the best braking effect.

New shoes must be driven with caution. After changing shoes, it is necessary to apply the brakes several times to eliminate the gap between the shoes and the brake disc, which can cause the foot to not brake and increase the risk of accidents.
When driving, be sure to follow the instructions above to maintain the zirconia ceramic cylinder liner. This can be more convenient and practical, and reduce costs.
