Cylinder pulling phenomenon:

Scuffing damage mechanism of most local damage due to sliding parts of lubricating oil membrane, the surface of the relative movement between the two prominent parts metal contact occurs first, and then local appear tiny "burning-out" phenomenon, and burning-out parts due to the components of relative motion and torn apart.

In the process of the metal surface hardening layer, when the destruction of hardening layer, produced by the metal abrasive will be adding surface wear mo materials.

In the event of a so-called "burning-out wear" in a short period of time, appear on the piston and cylinder liner surface and the center line of the cylinder parallel rough grinding mark, this is the scuffing phenomenon.

Serious when sliding parts sticking or completely Stuck and may even produce cracks in the two weak parts of the surface to cause mechanical damage, that is, to bite the cylinder.

Therefore, the root cause of the cylinder is melting wear.
