2KD cylinder liner Unboxing inspection video

Cause analysis of cylinder liner wear

2) Low filtration efficiency of air filter. The role of the air filter is to remove dust and sand particles contained in the air entering the cylinder to reduce the wear of the cylinder, piston and piston ring parts. The experiment shows that if the engine is not equipped with air filter, the wear of the cylinder will increase by 6-8 times. The air filter is not cleaned and maintained for a long time, and the filtration effect is poor, which will accelerate the wear of the cylinder liner.

3) Long-term low temperature operation. Running at low temperature for a long time, one is to cause poor combustion, carbon accumulation starts to spread from the upper part of the cylinder liner, causing serious abrasive wear on the upper part of the cylinder liner; The second is to cause electrochemical corrosion.

4) Often use inferior lubricating oil. Some owners in order to save money, often in roadside shops or illegal oil sellers to buy inferior lubricating oil to use, resulting in strong corrosion of the upper cylinder liner, its wear is 1-2 times larger than the normal value.
